In order to prolong the life of your FIRSTLINE BC748S replacement battery please read the following:
Your FIRSTLINE BC748S battery is charged during production in order to test it. Your FIRSTLINE BC748S rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your FIRSTLINE BC748S 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 FIRSTLINE BC748S battery and prolong the life of your camera power supply.
Your FIRSTLINE BC748S 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 BC748S battery will discharge. If you intend to leave your FIRSTLINE BC748S 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 FIRSTLINE BC748S battery.

Our BC748S batteries have a two year warranty, represent excellent value and meet or exceed the original specifications. We also offer free delivery on all our products including the BC748S battery.
