How to choose vape batteries
1
Match the size. Check whether your mod takes 18650, 20700 or 21700 cells before you order.
2
Check the amp rating. Higher-wattage mods need cells with a higher continuous amp rating. Check your mod's guidance.
3
Use matched pairs. In dual-battery mods use two cells of the same brand, capacity and age, and keep them together.
4
Inspect and store safely. Do not use cells with a torn wrap, and carry spares in a case, never loose with keys or coins.

Vape batteries: frequently asked questions
What are vape batteries?
Rechargeable high-drain cells that power box mods and other removable-battery vape devices.
What size battery do I need?
Check your mod. Common sizes are 18650, 20700 and 21700, and they are not interchangeable.
What does the amp rating mean?
It is how much current the cell can deliver safely. Use a cell rated for your mod's power output.
Can I use any two batteries in a dual-battery mod?
No. Use two matching cells of the same brand, capacity and age, and keep them as a pair.
How do I charge vape batteries?
Use an external charger such as those in our chargers collection, and do not leave cells charging unattended.
How should I carry spare batteries?
In a proper case, not loose in a pocket or bag with keys, coins or other metal.
When should I replace a battery?
If the wrap is torn or damaged, or the cell is dented, hot or swollen, stop using it and dispose of it safely.
How do I dispose of old batteries?
Recycle used cells at a battery recycling point rather than putting them in household waste.
Is delivery free?
Orders over £40 ship free across the UK, and orders placed before the 3:00 PM cut-off are dispatched quickly.
Do I need to be 18 to buy vaping products?
Yes. Vaping products may only be sold to people aged 18 or over in the UK, and Wolfvapes sells to adults only.
Products on this site are for adults aged 18 or over only.
