Best batteries for vaping

Updated: Oct 25, 2019




Most vapers these days are looking to blow the biggest clouds or use sub-ohm tanks, but to do this, batteries need to be able to put out a lot of power.


The majority of vaping devices require the use of a 18650 battery. These are easily available and work with most mods. However, because of the popularity of these batteries, there are a lot of fakes on the market - so you need to know what to look for when you're choosing one for your vape.


Below are a few things to consider to make sure you are getting the best battery for you.


Brand

The brand of the battery is one of the key things to keep in mind when purchasing a 18650 battery. The four main brands that have a good reputation are:

  • Samsung

  • Sony

  • Panasonic

  • LG


The continuous discharge rating

When it comes to vaping, this is the most important metric to consider. Before you can decide, you need to know how much current the device that you are trying to power has.

If you choose a battery that has a current less than what is needed in your device, then your battery will overheat because it's being used more than it should be.

Continuous discharge rating refers to the maximum current a battery can be discharged safely at a continuous rate without making any damage to the battery or reducing its capacity.


As we mentioned earlier, there are a lot of fakes on the market - so rewraps or batteries that are manufactured in China will usually exaggerate the CDR, or use different metrics instead.



Capacity

Capacity is calculated in mAh (milliampere-hours) and indicates the running time of the battery. There is currently no battery with a CDR over 30 amps and no 18650 battery that has a capacity at or over 3000 mAh that will have a CDR over 20 amps. These are the basic rules to follow, so if you come across a battery that doesn't fit with these, then you can pretty much assume these are fake or not rated properly.


Obviously, if it was an option, you would choose the battery with the highest capacity. However, this depends on the current rating. Inside each battery cell, you can only fit so much material, so you either have to choose between a high capacity battery or a high current battery.


Operating temperature

If you find your devices are constantly getting hot, then you are pushing the battery past its limits.

Batteries that go over 45C often, will run out a lot faster than ones that are running at a cool temperature. Increased temperature can also be dangerous as there is more risk of them bursting or exploding, especially if it is a lithium ion battery.


Flat button and top button

The last thing you will want to consider when looking for the best battery for your use is whether you want a flat top battery or a button top battery. This refers to the positive end of the battery.


As you may have guessed, a flat top battery has a flat surface, which can sometimes make your battery too short for your device. Whereas a button top battery has a small piece that sticks out at the top, which can make the battery too large to fit in your device. Therefore, before picking the best battery for you, you will need to see what your device requires.
