In order to prolong the life of your PIONEER VM51AC replacement battery please read the following:
Your PIONEER VM51AC battery is charged during production in order to test it. Your PIONEER VM51AC rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your PIONEER VM51AC 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 PIONEER VM51AC battery and prolong the life of your camera power supply.
Your PIONEER VM51AC 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 VM51AC battery will discharge. If you intend to leave your PIONEER VM51AC 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 PIONEER VM51AC battery.
