How long can I use the same vape batteries?
An 18650 vape battery’s life is determined by the number of cycles it has been through and how hard the battery has been pushed.
Generally, we would advise to replace your 18650 batteries every 18-24 months (or after 400-500 cycles) as this is when they start and lose charge capacity.
You should never use an 18650 that has been damaged, or shows signs of physical wear and tear as this could be extremely dangerous.
What size is an 18650 battery?
All vape batteries have their size dictated by the name of the battery.

- The final digit designates the shape of the battery.
Using this, you can work out that an 18650 vape battery is 18mm diameter, 65mm length and round (0).
What is the best 18650 battery for vaping?
Despite what you may read online, there is no single best 18650 battery for vaping – it depends on how you are using your vape device.
The two important numbers to look at when purchasing an 18650 vape battery are the amp rating and the capacity.
If a battery is 25A 2500mah, this means you can draw up to 25 amps and have a power capacity of 2500 milliamp hours.
The amp draw of your device can be calculated by using ohms law (or one of the many handy vape ohms law calculators online). This isn’t as important when using vape mods that contain protection chips inside of them, this was more for when people were using mechanical vape mods and did not have any inbuilt protection.
