Security system batteries are used to provide back-up power when the main AC power fails. Generally speaking, a security alarm battery will provide anywhere from an hours to 24 hours of backup power during a power failure.
Alarm batteries don't last forever. In time their capacity is reduced and if you don't replace them regularly, the alarm battery may only provide a few minutes of power when you need it the most.
A security system battery should be replaced every 2-3 years on average so they are ready when they're needed.
Our security alarm batteries are suitable for use in all common alarm systems including DSC, GE, Interlogix, Honeywell Vista, ADT, Chubb, Rogers.
CHOOSE THE RIGHT ALARM SYSTEM BATTERY
When looking for a replacement alarm battery, the main consideration is the size, voltage, capacity (AH rating) and terminal type.
Most standard alarm systems use 12V batteries. The most popular size is 4AH or 4.5AH which are interchangeable.
The next most common size is 7AH or 8AH which are also interchangeable.
Larger batteries allow your alarm system to run longer when power fails. An alarm battery typically has an F1 187 faston tab which is 0.187" or 4.75mm wide.
Some smaller alarm systems may have 6V batteries or custom batteries so it's important to identify the battery before ordering a replacement.
