Best 18650 Batteries 2018

The best 18650s on the market for vaping.
1st Place
Sony VTC5A

A great 25A battery made by Sony, a trusted name in battery manufacturing. With a high-ceiling for amps and long-running times, the Sony VTC5A is the top pick.

18650s are by far the most common batteries in vaping. They are readily available, reliable, and extensively tested, and the vast majority of mods come with 18650 compatibility. While newer batteries, such as 20700 and 21700, have raised the stakes, we rarely see them in dual or triple battery vape mods due to their larger size. Manufacturers still lean on 18650 as they combine a smaller size with tried and tested performance.

Due to the large availability of 18650s from electronics manufacturers, this list does not contain any rewrapped batteries. But it is not rare for 18650s to be counterfeited, so always do your research and only buy batteries from reputable vendors.

Note: Always practice battery safety when operating powerful lithium-ion cells. Make sure you understand Ohm’s law, especially if using mechanical mods. And only charge vape batteries in external and dedicated battery chargers.

Sony VTC5A

Sony VTC5A

One of the most trustworthy and balanced 18650s on the market, the Sony VTC5A is an all-rounder. A great 25-amp battery, with enough capacity to last through the day. One of the best 18650s for mechs if you build according to its amp limit, the VTC5A is also an excellent battery for use with regulated mods.

Samsung INR

Samsung 20S

That’s one of the latest entries in the 18650 market, and the hardest hitting available right now. Samsung’s 20S can support up to a 30-amp draw, making it the best 18650 to use on a mech mod with lower-resistance builds. It won’t last you that long, but it will serve you well when rebuilding with its high amp rating.

Sony VTC6

Sony VTC6

The VTC6 comes with a whopping 3000 mAh and Sony’s reliable brand name. Ideal for lower wattage ranges due to the limited amp draw, this is quite possibly the 18650 for MTL vaping available. If you want to raise the wattage a bit, pair two VTC6s together on a dual battery regulated mod.

Samsung 30Q

Samsung 30Q

The Samsung 30Q performs at a similar level to the Sony VTC6. Another lower output battery with a long running time, a couple of 30Qs on an MTL setup will have you forget when you last charged your device. Easily recognizable by their pink wrapper, these cells can keep your vape going for the long haul.

Samsung 25R

Samsung 25R

The Samsung 25R is one of the longest-standing tried and tested batteries on the market. There are two editions available that perform at a similar level, with the green wrap 25R having a slightly longer life cycle than the blue one. Samsung 25Rs are easy to find, not very expensive, and work great.

LG HG2

LG HG2

The LG brown is another solid choice for long-lasting batteries in the list and performs comparably to the other two, the Sony VTC6 and the Samsung 30Q. If you can’t find a Sony or a Samsung, go for the LG, you probably won’t even notice the difference. They are usually a bit cheaper than the VTC6s too.

How we picked the batteries

Choosing “best batteries” is not something to pick simply based on subjective likes. While our international team of experts and vape enthusiasts use the batteries on our lists, our recommendations and product selection could not have taken place without first going over the data offered by Battery Mooch.

Battery Mooch (or just Mooch) is the vape community’s expert tester of batteries. For a few years now, he’s been supplying the community with in-depth and reliable testing for the majority of batteries used in vaping.

This is not his list of best batteries, though all these batteries have been verified by his battery charts to be worthy of inclusion. Mooch and his highly detailed research can be found on his E-cigarette Forum blog, his channel on YouTube, and his recommendations on Reddit.

18650 ratings and specifications

What is a battery?-Infographic

Note: Some of the information in this section originally appeared in our article published in early 2016, written for Vaping360 by Battery Mooch.

Continuous Discharge Rating (CDR)
This is the rating that is used by reputable electronic manufacturers, and the one rating that we can use to compare battery discharge. When accurately rated, it signifies the current that a battery can be safely discharged at a continuous rate without taking damage or reducing its capacity.

Rewraps and Chinese manufactured batteries will often overstate the CDR, or use other ratings instead of it. One good example is the maximum discharge rating (or maximum discharge current), which may even be the only rating on the wrap. It is the maximum current that a battery can supply in short intervals (that are most of the times not mentioned on the rating). This is not a rating that should be taken into account when considering a battery, as it is often times misleading. Always look for the CDR of a battery, and cross-check ratings with online sources.

Capacity
Calculated in mAh (milliampere-hours), the capacity of a battery signifies its running time. One mAh is equal to the charge transferred by a steady current of one milliampere flowing for one hour. While this rating is sometimes overstated on battery wraps, this doesn’t happen as often as it does with discharge ratings.

Going over the ratings of reputable manufacturers, you will notice a pattern: there is always a trade-off between CDR and capacity. There is (still) no 18650 with a CDR over 30 amps. At the same time, no 18650 with a capacity at or over 3000 mAh, will have a CDR over 20 amps. Until further notice, any battery that is not rated according to these two rules can be assumed to be falsely rated.

Try to avoid rewraps, as the batteries that are used for them may change at any given time. With 18650s being so readily available, finding a battery from a reputable manufacturer should always be a priority.

Other devices powered by 18650s

18650s are commonly used in:

  • laptop batteries
  • cordless power tools
  • electronic vehicles
  • LED flashlights and more

The Tesla Roadster, the first production automobile to use rechargeable lithium-ion batteries, was powered by 18650s, as were the company’s Models X and S. Granted, there were thousands used for the electric vehicles’ battery packs, but they were still 18650s nonetheless.
