Sealed Lead-Acid Fire Alarm and Security Lighting Batteries
Security alarms are the sentinels of home safety, often operating in the background with a low-maintenance cadence. At their core, batteries keep these systems reliable, especially during power outages that could leave a home vulnerable. Most alarm system batteries are not behind the keypad but in a different box, usually in an interior bedroom closet. To replace your alarm system battery, leave the keypad alone and open the security system's power box instead.

Battery Tips for Fire Alarms and Security Systems
Most smoke detectors take 9V batteries. Be sure to replace them every six months and test your smoke alarms. Some smoke detectors use lithium batteries, and those can last as long as the device itself. Some smoke alarms use two or three AA batteries instead of 9V batteries. Consult the user manual for your specific model to identify the appropriate battery type.
Regardless of whether your device requires AAs or a 9V, it is essential to replace them every six months to ensure your smoke detector's effectiveness. How can I stop my smoke alarm from beeping?
Replace batteries every six months and you’ll prevent it from chirping for low batteries. If you just replaced the battery and it’s still beeping, you may need to replace the whole smoke alarm. A beeping smoke alarm typically indicates a low battery, error or the end of the device’s life after 10 years of use. How long do 9V batteries last in smoke detectors?
Six months is as long as you can trust a 9V alkaline battery in a smoke alarm. Alkaline batteries, from AAs to 9Vs, work well in heavy-drain applications or in applications that need occasional power, making them ideal for alarm systems.
