Best 18650 Battery Guide

The 18650 Battery is the quintessential battery for vaping. The majority of mods use this battery, and that’s what this page will cover. While most times you buy batteries, you just look for the fit in your device, it isn’t that simple when it comes to vaping. Think of the 18650 as the size of the AA, C, D batteries you buy at the store. That will only get you to the ones that will fit your box mod. Next you need to find the ones that will work best with your device. We have a great guild below that explains how to find the right one for you.

We’ve also listed below some of our favorite batteries based on the award category. There are three award categories with the first being best longevity. That is the battery that is built to last a long time between charges. The next award is the most durable and reliable which indicates which 18650 cell will stand up to the abuse of being used and continuously recharged over the life of the battery. The last award is the best high drain battery that goes to the best battery with high drain capability as the name suggests. While we prefer some specific 18650 cells over others for particular applications, there is no right fit for all. It will depend on how you do vape and how you want to vape with your device. So check out everything below and immerse yourself in the world of 18650 batteries.

The South Korean made HG2 18650 battery is manufactured by one of the most well known and highly respected brands on earth, LG. It was created in 2014 and came out for consumer use in 2015 intended for power tools. It was quickly picked up by vapers as being an excellent choice because its specifications make it the holy grail of vape cells. It is a battery that can be both high-drain and high-capacity, which is rare to find and something everyone wants. While the discharge limit is similar to the HE2/HE4 cells at 20A, the extra 500 mAh that those batteries don’t have is what sets it apart from them.

Several independent tests have confirmed that this device is the current king of high-drain. While some tests had it come in at 2960 mAh, most were able to get the 3000 mAh. You can fast charge this battery, but keep in mind that it will reduce the cycle life of any battery. You’re best off charging at standard speeds and having an extra to ensure the best performance. From our tests, we’ve got two days or more on temperature control mods with heavy use, so we highly recommend it.

The Samsung 25R 18650 cells are one of the most famous and widely used batteries in the vaping field. There are actually two versions of this battery. The first is the Samsung 25R2 which comes with a blue cover and the second is the Samsung 25R5 which comes with a green cover. We are discussing the green Samsung 25R5 in this post as one of our favorites. The real difference between the two is a better life cycle for the green covered one. Since the best parts of this battery are the life cycle and the capacity, it makes a difference to choose green over blue. You can expect to get at least 250 cycles with this battery before reaching 60% of the starting capacity. The capacity is quite large at 2500 mAh and will last you several days between charging with most mods.

Safety is key with batteries and this is going to be more for the vapers that are not looking for super high output with high drain capabilities. It will work in almost any mod, but you should know the limits of the batteries you are using. The average vaper will have no trouble using this battery normally and it would perform well in almost every case. If you are staying at 0.5 ohms or up, this is a great battery choice. If you’re looking to drop lower than that, we recommend looking into the VTC4 or VTC5 batteries.

The Sony VTC4 is beloved by all vapers for its safety and output and the VTC5 takes it to the next level. It’s designed for high wattage mods that need a high-drain battery (or two). Some will even use 3 or 4 batteries these days and the VTC5 is a great choice if you’re running over 200 watts of power to the atomizer. You will be protected since safety is the biggest benefit to the Sony VTC5. They actually hold their charge for quite a long time being 2600 mAh and have a very respectable life cycle. It operates between 2.5V and 4.2V and pairs nicely with the built-in safety features of today’s mods.

There is some debate about if this is a 20A or 30A battery but it is capable of outputting 30A continuously but most of the time it will operate with an output of 20A. If you want a true 30A battery, we would recommend the VTC4, but then you are also giving up 500mAh by doing so. Sony recommends you charge these with a high-quality charger rather than in your mod. You also want to keep the temperature stable and following recommendations will ensure your safety even more. These batteries are often faked due to their popularity and Sony is very controlling over who can sell them. So be sure to check for authenticity and only buy from reputable sites. If the price seems too good to be true, it probably is too good to be true.

Introduction to the 18650 Battery

Probably the most notorious battery for Vapers today, the humble 18650 has risen to become the near industry standard over the past few years. The rechargeable 18650 battery is a friend to the smallest box mod to the most complex mechanical mod.

Although newer or casual observers might be fooled into thinking these little lumps of Lithium Ion are pretty standard like other consumer batteries, they actually vary greatly. From capacity and voltage to the often wide range in quality and price points, finding the perfect battery can be a minefield. So we’ve put this handy little guide together so you won’t be left head scratching when you come to purchasing your first, or next, 18650 partner in crime.

As with most things in life, one size doesn’t fit all. Deciding on the best 18650 battery for your needs will as mentioned, depend on several areas.The key four factors you will need to consider on which one will fit your device and your own personal requirements are:

  • Capacity
  • Current Rating
  • Voltage
  • Operating Temperature

As with all electronic purchases, price, brand and warranty are also going to be considerations, as is avoiding cheap counterfeits too. However, they are often much easier to factor in once you know which type of 18650 is going to be right for you.

Assorted 18650 Batteries



The capacity of the 18650 battery is what will tell you how much charge the battery can hold and how long you can vape before recharging the 18650 battery. You’ll often see batteries advertised as high capacity and that’s the general category of batteries you want to get. However, you might ask how you can tell if it really is high capacity or a marketing tactic. Milliampere-hours is what you  look for and that is designated as mAh. It shows how many milliamps that can be drawn in an hour and is used to break down how long it will last.


If you look at the LG HE4 18650 35 AMP 2500 mAh battery (which is available for $8.46), the important information is the mAh in this part. 2500 mAh means it is rated to pull 2500 milliamps in one hour of use. That’s not realistic for vaping, but you could pull 2.5 amps in an hour. You can also do simple math to see that you could pull 1250 milliamps in 2 hours if you get it back to the 2500 mAh you can determine how long it will last.

LG 18650 HE4 Battery Testing Chart

While the math won’t be for everyone, you can follow a rule of thumb that is easy – the higher the mAh, the longer the battery will last. You should also keep in mind that no 18650 battery performs at 100% of what it is rated to be. They will also decrease in effectiveness over time. You do have to keep in mind that capacity isn’t everything when it comes to batteries. So, don’t just buy the highest mAh battery you can without knowing your requirements for current as well. High current batteries have lower capacity so you may need to walk a line on capacity and current.

One important note to include on capacity is that you should charge your batteries frequently regardless of the choice you make. If you don’t do this, it will greatly decrease the 18650 battery life if they sit dormant for a few months. It’s possible they may not even hold a charge if it goes long enough between charges. This simple reminder will save you from a mistake we made early on in vaping.

General Information

Safety is the number one priority for any advanced vaper that doesn’t want to run into issues. Determining the right amount of current for your box mod is simple, it’s in the specifications. If we look at the popular iJOY RDTA (see deal here) you can see that it has an output current of 1-45 amps. Since you probably won’t want to be at the max, you should consider the LG HG2 18650 20A 3000 mAh battery (available here for under $6.64 using coupon code “5OFF”). This is one of the most popular batteries in the vape word because it’s got the current rating of 20A and a decently high mAh at 3000. Since two of these batteries go in the iJoy RDTA, you could get 40A out at once out of them.

You can actually get to 45 amps but we recommend following specifications because many companies are not accurate in their stated specifications. The brands we trust for our own vape equipment as being accurate are Sony, LG, Samsung, and Panasonic. We tend to stay away from any other brands.  On top of that, you also need to make sure they are authentic when being sold as one of those 4 brands, but we’ll cover that later on.

LG HG2 18650 Batteries And iJoy RDTA Box Mod


When you are looking at current, you want to reference the continuous discharge rating or CDR instead of pulse ratings. This is also called the maximum continuous discharge and maximum continuous current and rate the batteries capabilities on a more consistent basis over pulse ratings. To simplify it, this is the maximum electrical current at which a battery can be discharged continuously before it will fail. If you want more CDR amps you will have to sacrifice mAh and run time. If you want more mAh and run time, you’ll have to sacrifice CDR amps. So many users who want higher CDR amps tend to buy multiple batteries to combat this issue.


Voltage is important for delivering the right amount of current to the coil so it is important to know what your box mod calls for. It is even more important for mechanical device users because it will pass everything through to the coil and create a harder hit the higher the voltage.

Voltage isn’t determined by current as batteries with the same current can have different voltages. You generally want to choose one that runs at the highest voltage for the longest time regardless of if you’re using a mechanical or regulated device. As a general rule of thumb, you can find the ones that run at a higher voltage by looking for ones that run at cooler temperatures, have a higher current rating, and a good capacity.  Many manufacturers list the voltage and it can vary depending on who the manufacturer is. Some non-major brand names tend to over exaggerate all their stats so buyer be warned.

Voltage For Popular 18650 Batteries Chart

Operating Temperature

When it comes to choose a 18650 battery one of the most overlooked and most important aspects is the temperature it runs at. This is huge for safety and makes a major difference in that regard. Aside from safety, batteries that overheat also damage the charging cells and don’t last as long because of it. As a safety tip, if your batteries are getting much hotter, you should definitely replace them. This is a sign of age or damage to the batteries because more resistance is present than it was designed for.

You will want to find the batteries that run at the lowest operating temperature so you don’t end up having to change the way you vape to accommodate your battery. The 18650 battery should work for you, not the other way around. If you have hot running batteries, you would need to lower the power level or use higher resistance coils and that is not what most advanced vapers want to do.

Operating Temperature Example 18650 HG2 Battery

Summary of 18650 Batteries

So, as you can see, there is no perfect battery. The idea of finding one is like finding a unicorn. In order to increase the value of one of the categories you want, you generally have to decrease the value of another. So it is important to find what is most important to you. Then look for those elements and try to balance the others well. The first way to sort the batteries should be current level and then determine the other factors from there.

We’ve provide a guide below on the best batteries for each current group. They are up to 20 amps, 20 amps to 30 amps, and 30 amps to 40 amps.  We do also recommend that you use the same two (or three) batteries in a device together. Don’t mix brands or types to ensure the best performance and life of your batteries. Even if you’re using the same brand and type, it is beneficial to have two sets that always get used together rather than mix and match.

Counterfeits and Rewraps

18650 Counterfeits

Counterfeits are an unfortunate part of the 18650 battery business. It’s incredibly easy to do since the batteries are plain in nature with printing just identifying what it is. This is especially true since the vaping products come mostly out of China. There is a high volume of counterfeit products that come from there on the US market. If a price is too good to be true, it probably is. There are deals to be found, it should be a red flag when it is too good of a deal without reason.

Authentic 18650 Battery

Red flags are about all you can do to prevent buying a counterfeit online. You can identify them once you have them though. This way you know not to buy from that store again and can warn others. The weight of an average 18650 battery is 45 grams and no less than 42 grams. If it weighs under that then it is trouble, if it weighs more, then you should be fine as well. Genuine sellers tend to list battery weight in the specifications so you can look out for that.

Another thing you can look at is the font. Counterfeiters will tend to make it good enough but major manufacturers will have the same print every time. You can also measure the other dimensions of the battery and do a visual inspection. It is a red flag when there is too much wear on the bottom. You’ll also know a fake when you use it because it won’t last as long and won’t work as well.

18650 Rewraps

The other item to be cautious about is rewrap batteries. These batteries are made by the big 4 brands and have another manufacturer’s label on them. While this is a way to score deals, it can also be a way to score a lower quality 18650 battery as well. Batteries that don’t meet the big 4 brand specifications will be sold off. Then the the batteries are purchased by a third party. The batteries are then wrapped with a new cover and sold to the public. We figure if it isn’t good enough for LG, Samsung, or Sony to sell it, we don’t want it. Not all rewrap batteries are bad, some do just buy the good quality ones to put their brand on it. So, you need to know the store selling them so you can determine how they conduct business.

Closing Points on our 18650 Battery Guide

You should be aware of what they are looking for in a battery. You can use this guide to determine what is best for you. Not all batteries are the same and there is no perfect 18650 battery. You should be aware of the brand you buy to make sure it’s a reputable company. Further, you should make sure you are buying from a reputable vendor. Buying fakes saves you money in the short term but costs you more in the long run. We recommend you use our list of batteries in this post as we have done the research and used them. Make sure you buy a good multi-battery charger and extra batteries so you can always have a good vape experience!

    Thanks for the info.
    I Wismec P80 which battery to use ?

  2. JD says:

    I have the wismec Predator which batteries are recommended for it?

    • Jimmy Hafrey says:

      It really depends on the wattage you want to use with it. I would recommend VTC5A batteries myself if you’re looking to go higher. VT6 can work well also. If you’re going lower wattage, then the HG2 would work.

  3. san says:

    Now I’m using Eleaf Pico 75W and I’m waiting to get Pico Squeeze and Ijoy Captain pd270 234W. Which is best for all? Now I’m using Samsung 25R. Thanks.

    • Jimmy Hafrey says:

      It really depends on how you vape and at what levels. The 25R may work for all 3, but there are so many factors. You probably want to have some extra batteries anyway so look into other options (in sets) for the other devices if you are going to buy others.

  4. Petros says:

    I made the mistake of buying low drain batteries instead of high drain and i just noticed that. What could be the problem if i use them beside the obvious low life usage of the battery? Can i use them with no issues until my new purchase of high drain samsungs 30Q for the eleaf pico arrive?

  5. Shelby says:

    Can you use a Samsung and a LG 18650 3000 mAH battery together in the same mod?

  6. Marc says:

    I run an alien mod 220 with a .4 ohm coil and usually LG HG2. What would be the highest wattage I can run these batteries too? Is 120 pretty safe, or are these batteries meant to run lower wattages, like 40-70? Or should I buy higher drain batteries for when I want to run at wattages above 100?

    • Marc says:

      Also which would you recoomend, the LG HG2 or the Purple Effest 3000 Mah?

    • Jimmy Hafrey says:

      Here’s the recommendation we’ve found:

      Under 120watts any 20amp battery or higher CDR battery will suit your needs, if needing more Mah for more runtime, then there are 3 in the 20amp CDR category that shine
      Samsung 30Q 3000mah 20amp CDR
      Sony VTC6 3000mah 20amp CDR
      LG HG2 3000mah 20amp CDR

      150watts and under, will need 25amp CDR batteries
      LG HD2, HD2C, HD4 2000 to 2200mah 25amp CDR
      Sony VTC5A 2500mah 25amp CDR

      180watts and below needs 30amp CDR batteries and there are only 3
      LG HB2, HB4, HB6 1500mah 30amp CDR

  7. Robert says:

    What kind of batteries should I use with the Smok T-Priv?

    • Jimmy Hafrey says:

      We found these suggestions:

      Under 120watts any 20amp battery or higher CDR battery will suit your needs, if needing more Mah for more runtime, then there are 3 in the 20amp CDR category that shine
      Samsung 30Q 3000mah 20amp CDR
      Sony VTC6 3000mah 20amp CDR
      LG HG2 3000mah 20amp CDR

      150watts and under, will need 25amp CDR batteries
      LG HD2, HD2C, HD4 2000 to 2200mah 25amp CDR
      Sony VTC5A 2500mah 25amp CDR

      180watts and below needs 30amp CDR batteries and there are only 3

  8. scott tracy says:

    i got a voodoo drag box for my birthday. they recommend 35A or higher what would you recommend for batteries to run this mod.

    • Jimmy Hafrey says:

      If it were me, I’d put the VTC6s in it from Sony. There is, however, a wide variety of batteries that could work with this and it does depend on what you’re looking to do with it.

  9. Faith Gil Torres says:

    Im using therion 133 dna200. Which battery is best? I vape between 50 to70 watts. Thanks

  10. April says:

    Got my smok gx 2/4 but im not really sure what battery to get so i will be able to use it on maximum.

    • Jimmy Hafrey says:

      It’s a bit of personal preference and I’d go with the Samsung 25Rs. Be sure to marry the battery sets together. So if you are going to use 4 in it, you should use the same 4 together every time. If you plan on switching down to 2, I would have a separate 2 batteries to put in and out. So you’d need a total of 6 batteries to do best practice for safety.

  11. Tim says:

    Hello Jimmy,

    I have a VT Inbox and I like to run a single coil between .3 and .4 ohms and I stick to the 30-40 watt range. What would the best battery be for me? I have some brown LG HG2 batteries, which I hope are genuine. Should I stick with these or would I be better served with another brand?

    • Jimmy Hafrey says:

      I think you’re fine with that battery for the duration of the life of it. After that, I’d switch to a Samsung 25R and see if you like that more. That’s the battery I would opt for myself.

  12. Dave says:

    What’s up Dustin, thanks for the article, lots of good info! Quick questions. I’m currently running a Smok alien at about 150V daily. Also, a Smok ProColor at 90 or 120 depending on the tank. Which batteries would you suggest? I’m currently using 2 sets of Imren 3000mah, 3.7v 20A/40A (20 cont discharge). They seem to work pretty good, I get about 24 hours from them. Also I have a pair of EFest 3000mah 3.7v 35A (20A cont). I have to say that these are the best I’ve ever tried. I get a good 36 hours from them.
    Basically am I using the correct batteries or should I switch it up? Thanks for the help!!

    • Jimmy Hafrey says:

      Hey Dave, Thanks for the kind words. We think you made a good choice at putting those batteries in for the mods you have. I’d personally go with the LG HG2 or the Samsung 30Q with that mod but you aren’t wrong in your choice so I wouldn’t throw them away by any means. Maybe when the life cycle goes on those, give the LG HG2s a shot. Just make sure you marry the batteries together and never mix them. Always use the same ones in the units at the same time.

  13. Paul Painter says:

    Awt Imr 3000mah 40a 18650 what’s it good I vape between 65-85 watts .15 coils normally what would be the best set of batteries for longer use before recharge

    • Jimmy Hafrey says:

      Without knowing your total setup, I can’t give a completely accurate answer but making some assumptions, I’d say the LG HG2 would be the best bet if you just want longevity and aren’t vaping at very high power settings.

  14. Claire says:

    Thanks, some great info here! Quick question as I can’t seem to find an answer anywhere, I’ve just ordered the SMOK Mag with TFV12 Prince Tank and not sure which batteries will be best? I’m not sure yet what watt I’ll be on but guess around 70W.

  15. Aldoo says:

    I bought efest 3500 20A sadllllly
    And i will use it with eleaf istick pico 75watt
    Is it working? Or i should bye a better one?

  16. JT says:

    I just got a nitecore D2 charger for Hohm life batteries(2x) but totally new to to vaping and the batteries… so I put them in the charger. They are charging at 3.55v but ik they can charge up to 4.2v but doesn’t seem to charge at the voltage so my question is does it sound like I’m doing this right? And how long does it take to charge 2 Hohm life 18650 batteries?

  17. Petros says:

    Hi there and happy new year. I chose the 30q for a series regulated mod and vtc5A for a parallel mech mod for lower resistance. Do you find it a good choice ,any other recommendations. Just for the record I like vaping around 50 -60 watts 0.3-0.4 ohms dual coils for series. And for lower ohms I choose parallel setting for safety but never below 0.1 ohms. Thanks for any advice.

  18. Justin says:

    The section titled “Current General Information” is misleading. It is stated that by using two cells with a 20A rating, 40A can be achieved. This is true only for mods that use cells in parallel, however most multi-cell mods are wired in series. The primary difference as it applies to deciding on which 18650 cells to purchase lies in how these different circuits utilize current. Two cells wired in series act as a single battery with double the voltage, but current will remain the same (two 3.7v 20A cells will equal a battery with 7.4v but still 20A). It is only when cells are in parallel that the current is doubled, in which case voltage remains at the voltage rating of one cell. For mods with cells in series, high current cells are unnecessary as the added voltage means less cureent is needed to maintain whatever power the user prefers. In a mod with cells in parallel, higher current cells are necessary because as the voltage decreases (batteries discharge), more current is needed to maintain the user’s preffered power setting.
    Do your research into the mod you own/ are looking to own before spending money on the overhyped “high current” cells. If you own a mod or the mod you are looking to own uses multiple cells in series, spending extra money on cells with high current ratings is pointless since you will have sufficient voltage to maintain your wattage. If you use a mech or have a mod with multiple cells in parallel, go for high amp cells, but remember that the total current output will be the current output of one cell multiplied by the number of total cells, so you should know the maximum current output rating for your device before purchasing cells and take caution not to exceed that value!

    My fiance and I just picked up a bunch of new mods and looking to use the right batteries. What would your recommendations be for the following listed below? And I was told once it is always important to start a new mod with fresh new batteries. Is that true?!? Thank You!!!

    Sense V-Jet
    Vaporesso Revenger X
    Tesla Punk
    Snow Xfeng

    • Jimmy Hafrey says:

      Yeah I would always start with fresh batteries because they are consumable products that become less effective with each charge. So you would want the best performance with a new mod generally. You always want to always use the same batteries together every time, rather than mixing and matching. As far as recommendations, here’s what I would use on all of these to max out the power: It will really depend on what you’re looking for but with all these being powerful mods, it is what I would choose.

  20. Gabe says:

    I got the smok mag what batteries you recommend?

  21. Mick newbrough says:

    I just bought
    A 3800mAh 3.7v and im trying to.see if they are worth what i paid for them

  22. Alex sandoval says:

    Im really green when it comes to batteries lol.
    A year ago i Bought a ijoy maxo (5 – 315watts) it came with 4 Samsung (INR18650-25R M) which I’ve been vaping with a baby beast 0.4ohms coils at 60 to 70 watts but now I just bought a 28mm The Sherman dual coil which reads 0.23 ohms which I vape on 150 watts (no higher), shall I keep using the same batteries (buy new ones obviously) or do you recommend using different ones for each tank?

    • Jimmy Hafrey says:

      Taking into account your other message as well, if you’ve had the batteries for a year they may be running nearing time to replace them. Each time you charge batteries, it lowers their life. So while they still work, you’d notice they don’t last as long as one way of telling. You can use the same batteries for the different tanks. You generally just want new batteries with new box mods to get the maximum performance and also want to marry them and use the same ones together all the time. The 25R is pretty versatile to work across the spectrum of vaping needs.

  23. Alex sandoval says:

    Forgot to mention that I only vape I the car (no chain vapin)some days I don’t even look at it. Still I’d still like a really durable and powerful battery (if there is such a thing)

  24. Ezzat says:

    Iam use sony VTC6 1860 3000mah, for mech mod
    Is this safty?

    • Jimmy Hafrey says:

      With Mechanical Mods, it isn’t so much about the battery you use, but about knowing the battery that you do choose. You need to know the discharge rate to not over discharge it. You need to be well aware of the resistance that will work for that battery and build the right coils. You really need to be on top of your ohms law as well.

  25. Andrea says:

    I’m stuck between buying the Smok Procolour and the Vaporesso Revenger X (edging towards the Revenger X as it’s apparently more durable). I can’t see myself vaping past 100w, do you think I should buy the Samsung 30q or 25r?

  26. Sanchia says:

    I just got new LG HG2’s to use in my Wismec P80 at 65 watts. It got noticeably warmer when i used it when compared to my Busbars 35A so removed it immediately. Is this normal?

  27. Alex says:

    Hi there, I vape at 75w, what batteries would you suggest me to use? I have a 2 battery slot mod. I’m currently using the Sony Vtc5a, are there any better than these?

  28. Ian says:

    Hello Jimmy, I got a Paranormal 250c mod and I have a LG HG2. My resistance on rta is .27 and using 50-60 watts, and on my rda the resistance is .45 running at 50 watts. Is my batteries ok or should I get a Sony VTC6? Thank you.

  29. Jacob says:

    Ordering an Aegis Legend 200W this week. What batteries should I order? And with those batteries, what wattage is best to smoke out of with moderate use throughout the day? New to all of this. Thank you.

    • Jimmy Hafrey says:

      I would use the VTC5’s from Sony: The wattage is really going to be a preference for you and dependent on your tank as well. I’d say start at about 40 and see if that’s a good fit and go from there. With those batteries you’ll be able to get up to the 200W if you desire it but I don’t think you will starting out.

  30. Chris Page says:

    I have a smok mag 225 at around 55-70 watts – can anyone recommend suitable batteries…..I like clouds, but am also trying to avoid having to charge 3 sets of batteries per day which is what I am currently having to do.

  31. Jacob R says:

    I’m going with the vaporesso polar kit I usually vape around 35-50 Watts was thinking about going with the brown lg hg2 3,000 think that’s good or the Sony vtc6 3,000 ? Thanks a lot.

  32. Cedric Calub says:

    I just got my first couple of external mods , and Ageis Legend and A Dovpo Topside, I was recomended The Samsung 30Qs for the Legend and Samsung 40Ts for the Topside And got them …. This being my first couple of External mods I’m really looking for some batteries that could last me the longest, are these good choices and what other batteries would u recomend for longetivity ? Also I bought 4 Lithicores 3000mah 3.7 v 18650s , So far they’ve pht up more puffs in the puff counter than the Samsung 30 Qs , Do new batteries need a couple charges before u can get a good average of how long they’ll last?

    • Jimmy Hafrey says:

      The LG HG2 is our choice for longevity. Batteries should be at their peak with the first use and they degrade from there. So it shouldn’t improve after a few uses. You may want to verify that they are authentic too as many times people sell knockoffs.

  33. Tom says:

    Just got a smok i-priv. It came with a .15 ohm coil preinstalled…… Can I use Efest IMR 18650 which is 3.7V/35A with a max continuous discharge of 20A?

  34. Ellen says:

    Totally new to vaping w/ rechargeable batteries and just bought a mod that requires two but doesn’t come with them. I ordered a couple of the Sony VTC5A 18650 2600mAh 25A but they could take up to 15 days to get here, apparently due to haz material/shipping.

    So here I sit, on Thursday, with a broken old Artery Nugget box mod (won’t charge), a new mod to arrive on Saturday but no batteries to put in it!

    Unfortunately I live in the middle of nowhere, Wisconsin and I can not find a vape shop that sells ANY of the batteries you’ve listed in this extremely helpful and informative, (save worthy for future reference) article.

    I know there are 18650 batteries made for flashlights, etc., sold by Batteries Plus, and I’m wondering if I could use a couple of them for the short term? And if so, what do I need to look for?

    Sorry about the length of this post. I’ll genuinely appreciate any feedback/insight you can share.

    Thank you!

    • Jimmy Hafrey says:

      Hi Ellen, thanks for the kind words. We hope you got this resolved as we were not in during the Holidays to help. We would not recommend using one designed for flashlights without really knowing what you’re doing. Any dangers from vaping tend to stem from improper battery usage. We have a team member from Wisconsin so we can understand being in the middle of nowhere. One option might be using Amazon Prime if you are in a rush and know a friend with a prime account.

  35. Matt says:

    What do you recommend for the VAPORESSO LUXE W/ SKRR tank? 50W-75W

  36. Jon says:

    Why do the Samsung 18650 25r say not for vaping on the package? I bought a couple of them for my k box and I haven’t seen that on the packaging before.

  37. Jeremy t smith says:

    I have a Smok G-Priv Baby which shows battery low when it’s not. Is there a specific battery I should be using? Thank you very much for your help!

  44. Ahmed says:

    Hi Jimmy, i use drag 2 and sony vtc6. Vaping between 50 to 60w, but the question here shall i get mxjo 3500 or be with sony ?

  45. Crystal says:

    Hello Jimmy, I just got the Uwell Crown IV 220w mod and it requires two batteries. In the manual it states that it requires 18650 batteries with a minimum output of 30A. I have no clue what that means and I currently have a .4 ohm coil 60-70w and it came with a .2 ohm coil 70-80w which is in my tank now. I will be vaping between 60-70 w on this device. I did order Efest IMR 18650 LiMn 3000 mAh Batteries with max discharge of 35A and continuous discharge of 20A but im not sure if that was the correct batteries to order. Can you help me with battery recommendations? Thank you so much for your time.

  46. Emily says:

    I am going to be buying a Vaporesso Luxe kit and I’m trying to figure out what batteries would be best for my needs. I’m going to start out at really low wattage but at the most I don’t think I’ll ever vape over 80w. What batteries would you recommend? Also looking for a really good, reliable, long lasting battery charger. What would you say is the best on the market? I would like a 4 bay battery charger. Also, do you know compatible coils by chance for the skrr-s tank that comes with the Luxe? Thank you for the help ahead of time. I’m new and still trying to figure everything out.

    • Jimmy Hafrey says:

      I’d probably just put the Samsung 25R batteries in. Always use them in married pairs. So use the same ones together all the time. I haven’t used that tank myself but maybe someone else will comment on that. Regarding the charger, I use the Nitecore D4.
