Is your Hills Reliance alarm showing a low battery warning, beeping, or failing to maintain power during a blackout?

This 12V 5Ah sealed lead acid (SLA) rechargeable battery is a replacement battery for compatible Hills Reliance R4, R8, NX4 and NX8 alarm systems.

Replacing an ageing alarm battery helps ensure your security system has reliable backup power if mains electricity is interrupted.

Why replace your Hills alarm battery?

Alarm backup batteries gradually lose their ability to hold a charge. A battery that is several years old may still appear to work normally while providing significantly less backup time during a power failure.

Replace your alarm battery if:

  • Your alarm displays a LOW BATTERY warning
  • The alarm panel is beeping intermittently
  • Your battery is around 3–4 years old
  • The alarm loses power quickly during a mains failure
  • The existing battery is swollen, leaking or visibly damaged
  • Your alarm reports a battery fault

How often should I replace my Hills alarm battery?

We recommend checking your alarm battery regularly and replacing it approximately every 3–4 years, depending on the battery's condition, charging environment and usage.

Why is my Hills alarm beeping?

A low or ageing backup battery is one common reason for an alarm panel to beep or display a low-battery warning. Replacing an old battery is often the first troubleshooting step. If the problem continues after replacement, the alarm system may require further diagnosis.

Can I replace my alarm battery without replacing the alarm system?

In many cases, yes. If the alarm panel itself is functioning correctly, replacing an ageing backup battery can restore reliable standby power without replacing the entire alarm system.
