DSE 905 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 ion 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 new DSE 905 electronic cigarette battery.
These batteries are replacements for your DSE 905 electronic cigarette and are rated at 900mAh.
