eGo 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 eGo 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 eGo electronic cigarette battery.

These replacements batteries for your eGo electronic cigarette are rated at 650mAh.

The eGo battery works with all eGo atomizers; whether it is the eGo Mega Cone, XL,  the standard eGo/510 atomizer, or the eGo-T(tank).
