Texecom Alarm Battery Replacement | Battery Types & Servicing

September 12, 2026

If you have a Texecom intruder alarm installed in your home or business, keeping the batteries in good condition is an important part of maintaining a reliable security system.

Depending on the Texecom system installed, batteries may be used inside wireless PIR movement detectors, door contacts, shock sensors, wireless keypads, external sounders and other wireless devices. The main alarm control panel also normally contains a rechargeable standby battery.

How Often Should Texecom Alarm Batteries Be Changed?

There isn’t one fixed replacement interval for every Texecom device. Battery life depends on the device, how often it operates, radio conditions, temperature and the type and quality of battery fitted.

As a practical maintenance approach, wireless device batteries should be checked during routine alarm servicing and replaced when the system reports a low battery condition or when testing shows replacement is appropriate.

The rechargeable standby battery inside the alarm control panel should also be tested during servicing. Its condition is more important than simply its age because the battery needs to keep the alarm operating if the mains electricity supply fails.

What Batteries Do Texecom Wireless Sensors Use?

Texecom has produced different wireless devices over the years, so the correct battery must always be confirmed from the exact device model before replacement.

Common Texecom wireless devices can use lithium batteries such as CR123A cells, while some products use different battery types or configurations.

Never assume that every Texecom PIR, door contact or shock sensor takes the same battery.

Wireless PIR Movement Detectors

Texecom Ricochet wireless PIR detectors commonly use lithium batteries. The exact battery depends on the detector model.

When replacing the battery, the engineer should also inspect the detector, check its tamper operation and confirm that the device is communicating correctly with the alarm panel.

Wireless Door Contacts and Shock Sensors

Wireless door contacts and combined contact and shock devices also contain replaceable batteries.

These devices can operate for long periods on a battery, but frequent activation, poor radio conditions and environmental conditions can reduce battery life.

The exact battery should be identified from the model before replacement.

Wireless Keypads

Some Texecom wireless keypads are battery powered. Battery requirements depend on the particular keypad.

A low keypad battery shouldn’t be ignored because the keypad is an important means of controlling the alarm system.

External Wireless Sounder

A wireless external bell box or sounder has its own battery arrangement. Because the external sounder is exposed to changing temperatures throughout the year, its battery condition should be checked as part of regular system maintenance.

Only the battery specified for the particular sounder should be installed.

What About the Battery Inside the Texecom Alarm Panel?

The main Texecom control panel normally contains a rechargeable sealed standby battery.

This is different from the disposable lithium batteries used by many wireless devices.

Its job is to keep the alarm system operating during a mains power failure. During an alarm service, the standby battery should be inspected and electrically tested rather than replaced purely because of a calendar date.

Signs of a weak standby battery can include power related faults, battery faults or the alarm system shutting down sooner than expected during a power cut.

What Does a Texecom Low Battery Warning Mean?

If a Texecom system reports a low battery or device battery fault, it normally identifies the affected wireless device through the alarm panel or keypad.

Don’t simply clear the warning and ignore it.

The affected device should be identified, the correct replacement battery fitted and the system tested afterwards to make sure the device is communicating and operating correctly.

Can I Change a Texecom Alarm Battery Myself?

Changing a battery may look straightforward, but opening an alarm detector, keypad or external sounder can activate the tamper circuit and generate an alarm or fault.

There is also a difference between replacing a disposable wireless sensor battery and working inside a mains powered alarm control panel.

If you’re unsure, having the system serviced by an alarm engineer is the safer option.
