In a hardwired alarm system the battery is found in the main control panel which is usually located in a closet. There will be a red wire and a black wire connected to the battery. Unplug both wires from the existing battery and plug them back into the new battery. Be sure to connect the red wire to the red terminal of the battery and the black wire to the black terminal of the battery.

Did you lose power before you received the call? If so, how long was the power out? In most cases the battery should maintain the system for 2-4 hours if a Lynx wireless system. If a Napco system, typically a battery will last 18-24 hours. If the power was out for a longer period of time, the battery should automatically recharge. If the battery does not recharge properly, you will be notified again in 24 hours. If you did not lose power or the power was off only a short period, the battery should be replaced.
