* The useful life of all Nicorex batteries is 300 charging cycles. This means that charging for even 5 minutes counts for one charging cycle. To ensure complete charging cycles we recommend using the battery until empty and only then charging. Further, we recommend that you always use two batteries to enjoy complete convenience of use: while one battery is in use, the other is being charged.
