Best 18650 Batteries for Vaping 2019 | Safest & Most Reliable Batteries

Best 18650 Batteries Banner

If you’re looking to find out which 18650 battery is best, the answer depends on what you need it for. Your build and how you vape will determine the battery that will be best for your needs. This is because currently, an 18650 battery can have either a high current rating or a high capacity but not both.

For example, some batteries may last a long time without having to be charged but can’t be discharged at high rates. Other batteries may perform great at high discharge rates, but will need to be charged again more frequently.

That’s why we’ve created a list of the best 18650 batteries for vaping 2019, to help you more easily choose the battery that’s right for you and your needs.


Battery Safety

If you’re using a mech mod, you should make sure that you always exercise proper battery safety precautions and have a firm understanding of Ohm’s Law. Knowing the amps that your build will be drawing from your battery is essential when using a mechanical mod, and you should pick a battery that is rated comfortably above that.

For example, If your build will draw 17A from your battery, a battery rated for 20A would be ideal. If you’re using a regulated mod, knowing your battery safety is always a good thing and you should always follow Ohm’s Law.

Battery safety and staying within the limits of your build and battery is paramount when it comes to vaping, because terrible things can happen if you aren’t careful. Batteries can and will explode if used improperly, and it’s your responsibility to make sure that you’re buying a battery that is both rated correctly for your build, and manufactured by a reputable company.


Quality Brands

Our list of the best 18650 batteries for vaping only includes LG, Samsung, and Sony branded batteries. While you can get cheap, or even knockoff 18650 batteries that state high current ratings and high capacities, these are frequently cells that did not pass the quality assurance checks from one of the big 3.

If it isn’t good enough for LG, Samsung, or Sony to sell, it probably isn’t good enough for you to buy. Be wary of cheap counterfeits, as these brands are frequently faked and will not perform the same as the original. For your safety, you should only purchase your batteries from a reputable vendor. If the price seems too good to be true, it probably is. However, in our opinion, price should not be a deciding factor when picking a battery for your vape.


Key Qualities of a Great Battery

There are four key factors that you should consider when picking the best battery for your vape:

  • High current rating
  • High capacity
  • High voltage when vaping
  • Low Operating Temperature

High Current Rating

A high current rating is extremely important when choosing a battery if you’re planning on running a low ohm build. The current rating on a battery is the maximum current that the battery can safely discharge at one time. For example, imagine we have a bottle filled with water. The size of the bottle opening limits the amount of water that can be poured out at one time. In this analogy, the size of the opening would be the maximum current rating, and the size of the water bottle itself would be the battery capacity.

Some batteries with a high current rating are able to discharge up to 30A without overheating. However, this doesn’t mean that you should just go out and buy the battery with the highest current rating. While this would definitely be the safest approach, you would be sacrificing battery capacity in return. Instead, you should use the Ohm’s Law calculator to properly calculate the amps you will be drawing from your battery, and pick a battery that is rated comfortably above that.

High Capacity

A higher capacity in an 18650 battery means that it will be able to deliver power for longer without having to be recharged. Capacity is measured in milliampere-hours, and is a measure of how many milliamps we can draw from the battery for how many hours. Now, the milliamps you will be drawing from your battery will be dependent on your build, but this means that a 3000mAh battery will be able to deliver power for twice as long as a 1500mAh battery under the same conditions without having to be recharged.

High Voltage

A high voltage is desirable in an 18650 battery because different batteries will deliver different voltages. For vapers using a mechanical device, a battery with a higher voltage will “hit harder” and deliver more current to the coil, therefore creating more vapor.

For those with regulated mods, a higher voltage is still beneficial because it means that your mod doesn’t have to work as hard, and thus won’t have to draw as much current from the battery.

All of the best 18650 batteries for vaping have a high voltage, and will deliver the hit and vapor that you desire when combined with a suitable rig.  

Low Operating Temperature

Having a battery that operates at a safe temperature is one of the most important aspects you should consider when purchasing a battery. Heat is the number one cause of aging and damage to batteries, and a battery that runs too hot will greatly shorten its lifespan. Instead of being able to use the battery for a year or longer, you may find yourself having to replace it much sooner.

In the worst case, if your battery isn’t rated for the current that you are trying to draw from it, the battery can vent or even explode. As previously mentioned, battery safety is paramount and if you simply know your battery safety, ohm’s law, and choose a battery that is rated for your build, you will not encounter any problems.


THE BEST 18650 BATTERIES FOR VAPING 2019

We’ve divided our list of the best 18650 batteries for vaping into three categories, to more easily help you choose the battery that is right for your needs.

LG HG2LG HG2 Vaping Battery

3000mAh Capacity
20A Continuous Discharge Rating
4.2V Full Charge Voltage
3.6V Normal Voltage

The LG HG2 takes a solid first place as the best battery you can buy for up to 20A. The HG2’s large 3000mAh capacity and ability to comfortably discharge up to 20A while remaining at a cool and safe operating temperature are the main features that make it a great battery.

The LG HG2 has a full charge voltage of 4.2V, but will quickly drop off to 3.6V when used at 20A. From there, voltage will slowly decrease with use until the minimum voltage of 3.2V is reached.

The 3000mAh capacity of the LG HG2 is amazing, and will mean less frequent charging.  You may even get multiple days of use from one charge, depending on how much you vape.

If you’re looking for a battery that will operate cool, function safely all the way up to 20A, the LG HG2 should be your first choice.
