Batteries in a vape heat up the coil in the tank so that the e-liquid can turn into vapour. Batteries vary between vape mods, but there are two main types: 18650s and 22650s.
18650s are the most popular batteries for mods by far. The numbers mean that they are 18mm in diameter, 65mm in height, and have no width (they're round). Even though they're clunkier than the average double A, they're great at holding long lasting power for a reliable vaping experience. They charge to a 4.4V maximum, about 0.5x the battery capacity.
22650s are slightly larger, with a 22mm diameter and 65mm height (they're also circular). They hold more charge and so can have a longer run time between charges. They work well in VV (variable voltage) box mods. These generally charge to 4.2V maximum.
There's also the difference between an internal and external battery for your vape. Internal batteries are contained within an all-in-one vape unit, meaning when built-in batteries die, the whole vape has to be replaced. When removable batteries die, they can be replaced, meaning a lower long-term cost.
If you want to take the next step in your vaping journey, consider what variations your batteries can have. Begin learning about volts, amps and ohms; capacity (or mAh rating); and temperature. Once you understand this, you can begin to play around with other things like continuous discharge rating, which affects the maximum constant current you can draw without damaging a battery. There's a world of vaping beyond your e-cigarette to discover.
Frequently Asked Questions
Are vape batteries lithium?
Yes! With a few exceptions, most vapes use lithium-ion batteries. There are, however, different kinds of lithium-ion batteries.
Lithium IMR (manganese) batteries allow a high current but low temperatures. They're super safe, meaning you can scale back the protection on your mod, and for this reason, they're more common.
Lithium ICR (cobalt) batteries work best at lower output levels, providing a higher mAh (milliampere-hours) capacity than IMR batteries. Because of this, they're significantly riskier, more likely to cause damage to you or your vape, and come installed with protective circuitry. ICR batteries are basically obsolete when it comes to vaping, as the IMR alternatives are much safer and most vapes use a higher output level now.
Can my vape or battery explode?
The simple answer is that properly maintained, safely stored, and legitimate batteries almost never cause damage. Batteries have caused harm in the past, but almost exclusively from misuse and mishandling.
Here are some tips for safer battery handling:
A big no-no for battery safety is keeping a loose battery in your pocket, where it can rub against keys or coins and create a spark.
Check your batteries regularly to make sure the wrapping is secure. This is especially key if you have re-wrapped your battery,
Charging the battery with the wrong USB cable, rather than the battery charger that came with the device, can be dangerous. Always use a USB-C charger specific to your vape.
Never charge batteries overnight or leave a charger unattended.
If you're using a mechanical, rather than a regulated mod, make sure you have a solid understanding of Ohm's Law, otherwise your e-cig can become volatile.
The longer you have batteries - especially if you've not used them in a while - the less reliable they become.
Overall, the key is to properly store and charge your batteries, replacing them if the way they hold charge changes or they become damaged.
Can vape batteries stop working?
Unfortunately, yes. Batteries are rechargeable, but not immortal. Look after it well and it might stick around for a few more years than average, though.
Do all vape batteries come with a charger?
Almost all internal batteries come with a USB-C cable, but not all removable batteries come with a charger. If you need a new charger, double check what kind your rechargeable battery, mod, or e-cig takes, and then check out our range of reputable chargers and cables.
How much do vape batteries cost?
Usually, a high quality mod battery will cost between £5 and £10. Internal batteries can be around £15, depending on the complexity of your mod.
Which side of my battery is positive?
The negative end of your battery has a flat top, and the positive end has a raised nub in the middle.
Can I rewrap my battery?
If the wrapping on your e-cig battery has become loose, this can be a safety hazard. It's not safe to use batteries like this, so yes, you can - and should - rewrap your vape battery, safely.
Should I marry my vape batteries?
Yes! Marrying means keeping two external batteries together (you don't need to worry about marrying built-in ones). By keeping them together, they're more likely to both hold charge at the same rate and stop one battery doing all the work, meaning they last longer overall.
