Alarm Batteries by Capacity

Alarm Batteries by Capacity make it easy to choose the right backup power for your home or commercial security system. Whether you need a compact battery for a small control panel or a higher capacity option for larger systems, you’ll find dependable AGM and sealed lead acid units designed for continuous standby use. These batteries support burglar alarms, intruder panels, communication modules, PIR sensors and safety-critical components that must stay powered during outages.

Common capacities such as 12V 1.3Ah, 2.1Ah, 3.2Ah, 4Ah, 7Ah and 9Ah are used across a wide range of alarm brands and system sizes. Lower capacities are ideal for smaller domestic panels and compact enclosures, while higher capacity batteries provide longer backup time for systems with more sensors, sirens or communication hardware. Each battery delivers stable voltage, long service life and strong float performance for year round reliability.

Choosing the correct capacity helps ensure your alarm system runs smoothly and maintains full protection during power cuts. Higher capacity batteries can support extended standby time, reduce strain on the system and improve overall reliability. With maintenance free, leak proof construction and durable internal design, these batteries provide consistent backup power to keep your security system ready at all times.
