510 electronic cigarette rechargeable batteries are lithium ion batteries and over time can lose the ability to hold a charge. This is normal and can be avoided by replacing batteries every few months.

Since no one lithium 510 electronic cigarette battery is the same, there is no way to say how long it will last.
Some companies will say they are good for so many "puffs" or "recharges" but this is inconsistent.
We recommend that you be aware of how your electronic cigarette functions and how long your batteries last.
Once you start noticing your battery not holding a charge, replace it with a fresh new 510 electronic cigarette battery.
These 510 electronic cigarette batteries are rated at 180mAh.
