In order to prolong the life of your SUNPAK AI33AFK replacement battery please read the following:
Your SUNPAK AI33AFK battery is charged during production in order to test it. Your SUNPAK AI33AFK rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your SUNPAK AI33AFK 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 SUNPAK AI33AFK battery and prolong the life of your camera power supply.
Your SUNPAK AI33AFK 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 AI33AFK battery will discharge. If you intend to leave your SUNPAK AI33AFK 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 SUNPAK AI33AFK battery.
