In order to prolong the life of your HITACHI DZ-GX3300E replacement battery please read the following:

Your HITACHI DZ-GX3300E battery is charged during production in order to test it. Your HITACHI DZ-GX3300E rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your HITACHI DZ-GX3300E 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 HITACHI DZ-GX3300E battery and prolong the life of your camera power supply.

Your HITACHI DZ-GX3300E 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 DZ-GX3300E battery will discharge. If you intend to leave your HITACHI DZ-GX3300E 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 HITACHI DZ-GX3300E battery.
