Best 18650 Batteries for Vaping in 2021

# 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 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

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.

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.

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.

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.

My way of understanding the significance of vaping came not only through the disruption of smoking but its effects on society as a whole. Now I bring people to vaping and bring vaping to people. I love using new gear, writing in-depth reviews and generally nerding out about vaping to like-minded people.
