Do All Burglar Alarms Have Batteries?
Not necessarily! A lot of traditional bell only or alert only burglar alarms are wired into the mains.
This made them expensive to install, difficult to maintain, and meant significant work needed to be performed on the property to provide adequate protection.
We’re now in the age where wireless communications can be used for critical systems, like Verisure’s ZeroVision home alarm system.
This is where long-lasting batteries come into their own. With wireless sensors, there is no mains connection, allowing them to be simply and subtly installed in areas that need protection in your property.
However – as we all know – batteries don’t last forever.
Although many burglar alarm sensors use relatively small amounts of power on a consistent basis, the batteries are still being depleted.

Yes — to ensure that your alarm doesn’t suffer any downtime and make sure it’s there to protect you when it really matters.
Many modern burglar alarms have multiple components, i.e. different sensors that perform different kinds of monitoring.
If you have a wireless security system, which wasn’t hard-wired into the main electrical circuit of your property, you’ll need to replace the batteries in the wireless sensors in the system periodically.
With Verisure alarms — you’ll have fully-inclusive maintenance and the team will ensure that your equipment is always maintained.
Whichever supplier you chose for your home security system, they should provide a simple guide for replacing the batteries, if it can be done by the user, or a support network that will help you maintain your alarm.
Generally, photodetectors or security cameras that are completely wireless will need battery replacements or to be charged most often. However, shock sensors will also eventually need to have their batteries replaced.
How Long Do Burglar Alarm Batteries Last?
This is a very difficult question to answer without knowing the specific sensors, power requirements and types of batteries used.
But for Verisure’s sensors, we have included an estimation of battery life below:
| Sensor | Battery Type | Estimated Battery Life |
|---|---|---|
| Shock Sensor | 2 x 1.5V AAA LR03 Alkaline | ~5 Years |
| Smoke Detector | 2 x 1.5V LR6 AA Batteries | ~3 Years |
| Siren Voice Keypad (SVK) | 6 x AA Alkaline battery | ~1 Year |
| Outdoor Security Camera | Rechargeable Lithium Battery | Up to 1 Year |
| Outdoor Photo Detector | Rechargeable Lithium Battery | Up to 7 Years |
| Central Unit | Backup Battery if Mains Fails | Up to 48 Hours |
These are not guaranteed battery life figures, but should give you an idea of when batteries might need replacing in different sensors in your burglar alarm system.
