21700 Vape Batteries

21700 vape batteries are a less commonly used vape battery due to their size. They’re compatible with most larger kits and mods and often have an increased power output thanks to their larger size. Please note that these will not fit in a kit that’s listed for use with 18650 batteries.

21700 refers to the size of the battery and not the amount of power it holds. The power can be found in the title of the product and will have ‘mAh’ after it. The biggest 21700 vape battery that you can get is the Vapcell P42A which comes in at 4200mAh. To help keep you safe we have comprised a list of helpful battery safety tips:

1. Always use a battery charger that is rated for Li-ion cells. Always use a battery case to transport where possible.
2. Never leave a battery on charge unattended. Batteries should never be loose in pocket or bag. All lithium batteries have a cycle-life, however, a battery should be replaced every 2 years – whichever comes first.
3. Never continue to use a battery with a broken PVC wrap. Never completely discharge batteries. Never expose to extreme heat.

CAUTION: Using rechargeable batteries always comes with an element of risk.
