ADT security services provide electronic security systems and solutions for all types of spaces. Your ADT alarm system is operated by a series of batteries located in the master keypad and any other remote wireless sensors. ADT batteries are sealed rechargeable batteries and do not require an external charger.

Battery Location

In the ADT alarm system, the back of the main alarm keypad -- the battery drawer -- contains either one 9-volt alkaline battery or six 1.5-volt alkaline batteries, depending on your system. In addition, all additional remote sensors also contain batteries. Remote sensors either contain one 9-volt alkaline battery or one 3-volt lithium battery.

Battery Life

The battery life of ADT alarm system batteries is up to 4 to 5 years for most home alarm system batteries. Battery life for batteries used in ADT's commercial alarm systems vary. A display message of 00 on the master keypad represents a low battery and indicates the need to change the battery within 30 days.

Notes

As a security precaution, only replace batteries with the same type of battery removed. For example, if your alarm system consists of a lithium battery, replace it only with a lithium battery.
