In order to prolong the life of your VIVANCO MP3016Y replacement battery please read the following:

Your VIVANCO MP3016Y battery is charged during production in order to test it. Your VIVANCO MP3016Y rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your VIVANCO MP3016Y 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 VIVANCO MP3016Y battery and prolong the life of your camera power supply.

Your VIVANCO MP3016Y 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 MP3016Y battery will discharge. If you intend to leave your VIVANCO MP3016Y 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 VIVANCO MP3016Y battery.
