In order to prolong the life of your ROWNSONIC JP20 replacement battery please read the following:

Your ROWNSONIC JP20 battery is charged during production in order to test it. Your ROWNSONIC JP20 rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your ROWNSONIC JP20 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 ROWNSONIC JP20 battery and prolong the life of your camera power supply.

Your ROWNSONIC JP20 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 JP20 battery will discharge. If you intend to leave your ROWNSONIC JP20 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 ROWNSONIC JP20 battery.
