Product Review

You have to CHARGE IT - It is a re-chargeable battery. Exact OEM replacement for the battery that comes in Viper 7756V, Clifford 7756X and Python 7756P remotes. DOES NOT WORK with other Remotes / Batteries that may look similar. You will need a TINY phillips head screw driver to open your remote's case to change your battery. BE CAREFUL AND GO SLOWLY. It is not difficult but you are working with delicate parts than can be damaged if handled roughly. [SPECIFICATIONS: 3.7V - 100mAh. Size of battery and connector plug are exactly the same as your original, because these batteries are the same as the original - Same model # and manufacturer]
