Your NP-80, battery is charged during production in order to test it. Your NP-80,  rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your NP-80, battery will have to be charged before you use it. You can use your existing charger or an external charger this will optimize charging of your NP-80, battery and prolong the life of your camera power supply.

 Your NP-80,  rechargeable battery discharges slowly and progressively when not in use. The self discharge rate is about 1% of the battery's capacity per day at room temperature. The higher the temperature, the faster your NP-80, battery will discharge. If you intend to leave your NP-80, battery for a prolonged period without use then a service charge is recommended from time to time, taking in to account the self discharge rate and time between using your NP-80, battery.
