#1 Samsung 30Q INR 18650 3000mAh

Samsung is another company that needs no introduction. They are taking a swing at 18650 batteries, and they are pretty on par with what the user would expect. They perform well enough, but they are not really stand out batteries. In fact, they are standard in every sense of the word. They come with the standard 3000 mAh, which is fine. It features an underwhelming 15 amps of continuous discharge, and the user can definitely get by with that. It is just not the best. Keeping the trend of standard going, the Samsung INR 18650 features 3.6 V of power. This is definitely a mid-range battery with standard specifications. That being said, its value is fantastic. These batteries will be great for those with an extremely tight budget, and they will be ideal for those that like to vape at low wattages.

The Aspire 18650 cell is a true-wrapped cell that has a maximum discharge rate of 40A. The cell performs well with high-drain, high-wattage devices either as a single cell or as the second cell in a dual-18650 device.

This lithium-ion cell has a yellow and black wrapping with the Aspire logo, along with its internal capacity of 1800mAh printed on its side. The cell has a flat-top design for its positive contact. The cell is not re-wrapped and is an authentic Aspire battery, made by the manufacturer.

Charging Time:
Nominal Voltage:


  • Good for high-wattage devices
  • Tough, durable wrapping
  • Lightweight and easy-to-install

The Samsung brand is a trusted name in electronics. So it would make sense that their batteries are among the top-rated in vaping circles. This Samsung 25R cell is rated at 18650 and features a battery capacity of 2500mAh, which is not like the 30Q, which has a 3000mAh capacity. The Samsung 25R can output a continuous 3.6V and has a full charge of 4.2V. The 25R comes in a two-pack and can power at least 250 power cycles before dropping in output. The cells use a flat-top design and are ideally suited for high-wattage devices.

#5 LG HE2 18650 2500mAh 20A Battery

A Lightweight Battery with Plenty of Storage

Nominal Voltage:


  • Great for box mods and vaporizers
  • Quick, 1.5A charging
  • A large capacity
  • Great for dual-18650 devices


  • Wrap tears easily

The LG HE2 is a 18650 battery with a 20A continuous output. The cell is very lightweight, weighing only 48g (1.6″) and stands at 65mm (2.5″). With these measurements, the cell is well-placed to power various single or dual-18650 devices. The battery has a capacity of 2500mAh and has a continuous output of about 3.6V. It is designed with high-wattage vapers in mind, as a dual-18650 device would need the amount of voltage this cell puts out. The cell has heavy-duty wrapping and is resistant to everyday wear and tear.

A Few Things About Best Vape Mod Batteries to Know

18650 batteries use lithium-ions to give them the ability to recharge quickly and repeatedly. They are made of a lithium and carbon combination, primarily because lithium is very reactive and is capable of producing and storing ample amounts of energy within its ionic bonds, hence lithium-ion batteries.

This stored energy lasts incredibly well too – once completely charged, these batteries only lose about 5% of their charge throughout an entire month while going unused. They are also very safe and provide dependable connections. These two reasons are why they are primarily chosen for vaporizers. Vapes can trust that their battery will not start to quickly lose life, or leak dangerous chemicals all over the inside of their precious mod.

Vape Mod Battery: Maximum Discharge: Nominal Voltage: Capacity: Price:
SAMSUNG INR 18650 3000MAH 20A 3.6V 3000mAh $8.95
Aspire 18650 Battery 40A 3.7V 1800 mAh $9.99
RadioShack INR 18650 15A 3000mAh Battery 15A 4.2V 3000mAh $18
Samsung 25R 18650 2500mAh 20A Battery 20A 3.6V 2500mAh $7.95
LG HE2 18650 2500mAh 20A Battery 20A 3.6V 2500mAh $4.39

As an added bonus, 18650 lithium-ion batteries have no memory effect, which means that vapers can begin recharging their unit even if it is not completely dead. This is great for when vapers are leaving the house, and want to make sure they have all the juice they can before heading out the door. 40% of the batteries in the world are lithium-ion for all of these great reasons, and 18650 types are definitely the most popular. They are not only used in the vaping scene, but also many other technology devices such as computers, cars, solar panels, and tools, etc. They are essentially used in nearly any electronic device one is able to think of.

Those searching for the best vape mod batteries are in the right place! Prevent the headache that comes with purchasing a disappointing set of batteries and take a look at our list of the best on the market.
Vape Batteries With Charger image
Most 18650 batteries look very similar and serve the same purpose, so does it even matter which to buy? Yes, the battery that you buy will impact your vaping experience. 18650 batteries have a few variables.

  • Milliamp Hours (mAh) are simple to understand. They express the capacity of the battery. A battery with 3000mAh will outlast one with 2500 mAh.
  • Amperage (A) is a way of measuring the output of power, and in unregulated mods, it can have a big effect on the experience. In more common, regulated mods, the amperage does not have as direct an effect on the vaping experience. Rather, batteries with higher amperage are likely to outlast those with lower amperage in regulated mods.
  • Voltage (V) is another measure of power, but unlike amperage, it is the measure of potential power in a device.

Amperage and Voltage are often confused, but don’t let it stump you. Voltage is the measurement of power within the device, and that power causes the flow of energy. That flow of energy is measured in amps. An easy way to understand this is to compare it to a water pump. The pressure within the pump that pushes the water out is comparable to the voltage, and the resulting flow of water is comparable to amperage.
Buy Best Vape Mod batteries image
There is one more thing you should know before buying a battery. Fake 18650s are rampant. People constantly sold batteries with fake specifications advertised and printed on the battery. They are sometimes indistinguishable from the real thing to the naked eye, and there are not many ways to tell them apart other than their terrible performance after it is too late. These fake batteries often times do not contain lithium-ion technology inside them, and do not last nearly as long, nor are they as safe. They are going to come from vendors like DirectVapor, and other trusted sites. When purchasing a 18650 battery, make sure it is from a reputable source. Ways to tell whether or not it is fake is by weighing it. If it weighs less than 40 grams, that is a red flag.

Where to buy 18650 batteries

18650 batteries are fairly easy to find. They are by far the most used battery for vaping, and they can be bought at almost any local vape shop. On the off chance that there is no vape shop in the town, they can be found elsewhere. Many common retail stores carry 18650 batteries. If vape shops and retail stores are not options, there is always the online route! You can purchase them on a plethora of online sites. It is possible to order one today directly from manufacturers or from third-party retailers like DirectVapor and other online vape stores. It is also possible, however, to purchase an 18650 battery from a store that has nothing to do with vaping. Well known trustworthy retailers are great places to buy these batteries. Since they are not that expensive, there is no need to search for them secondhand.

    Umm, you got the numbering system a bit wrong. The first 2 digits are indeed the diameter in millimeters but the remaining 3 digits are NOT the length as you explained it. The length is the following 3 digits are length in tenths of a millimeter. Think about it… 650mm is friggin 25 inches!! In reality an 18650 is 18mm dia 65.0mm len.

    Thanks for taking the time to present this info. Your descriptions of the terms helped and were logical and easy to understand. That said it is confusing to use your explanations, look at the battery specs and understand why several of the batterys with superior specs are listed low on the list. Any chance you could explain for us?

    I’m new to vaping and thinking of buying a smok mag 225 watt kit. I have some Sony vtc6 flat top batteries and some Panasonic NCR18650B which is button top. I think they are both around 3000 to 3500 mah batteries. I didn’t want to have to buy more batteries if the ones I have will work. I want a battery that will last for a long time and to get the best vaping experience. If there is a better battery for vaping with this smok mag kit than the ones I have I don’t mind buying more because I use the ones I have in flashlights anyway. I just want to get the best vaping experience and would greatly appreciate any help that you could give me. Thanks in advance and this was a great post

    Great article and very easy to understand even to those of us who have no clue what all the “numbers” mean on a battery..
    I do have one question… What are the trusted websites that sell these batteries at a reasonable price without having to worry about getting ripped off with a rewrap ?? Thank you for any help..

      Are you saying direct vapor sells fake batteries with no knowledge of them being fake or that direct vapor purposely sell them and rip people off?

      I actually just bought 2 2packs from Vape wild. They seem like a tough battery. They are NOT what I needed though. I needed 18650 not 21700. I paid $24.00 a pack for a total of 48.00 I just wish they were the correct size.
