In order to prolong the life of your FUJIX F850 replacement battery please read the following:

Your FUJIX F850 battery is charged during production in order to test it. Your FUJIX F850 rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your FUJIX F850 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 FUJIX F850 battery and prolong the life of your camera power supply.

Your FUJIX F850 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 F850 battery will discharge. If you intend to leave your FUJIX F850 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 FUJIX F850 battery.
