In order to prolong the life of your TELEFUNKEN A858P replacement battery please read the following:
Your TELEFUNKEN A858P battery is charged during production in order to test it. Your TELEFUNKEN A858P rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your TELEFUNKEN A858P 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 TELEFUNKEN A858P battery and prolong the life of your camera power supply.
Your TELEFUNKEN A858P 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 A858P battery will discharge. If you intend to leave your TELEFUNKEN A858P 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 TELEFUNKEN A858P battery.
