CAUTION– RISK OF EXPLOSION OR FIRE IF BATTERY IS INSTALLED INCORRECTY OR WITH AN INCORRECT TYPE. INCORRECTLY CONNECTING POWER OR ANY TERMINALS CAN DAMAGE YOUR ALARM BEYOND REPAIR. DISPOSE OF BATTERIES ACCORDING TO THE MANUFACTURERS INSTRUCTIONS. CONTACT US FOR REPLACEMENT BATTERIES
The battery in your home alarm system is intended to keep it running even when the power in your home goes out. A 12v 7Ah battery can provide from several days to potentially weeks of backup power for your alarm system so it can run and continue to protect your home in the event of short or extended power outages.
Under ideal conditions (minimal outages and power fluctuations) one of these type of batteries should last from 5-10 years. They can last longer but they become very unreliable, as all batteries do over long periods of time. It is recommended to change your alarm battery as a precaution every 5 years or whenever convenient, soon thereafter. If any abnormalities are noticed or your alarm is serviced you should also strongly consider changing your battery as this can eliminate possible issues.
If your alarm battery has issues your alarm system should alert you: A Hills XR Pro or Reliance with a ComNav will send you a notification specifically stating low battery or battery failure. If AC power fails you may not get this notification until after power is restored as your modem (internet connection) may also be affected and the system can’t send alerts until your internet comes back up.
Your Codepad will also alert you to power issues: Depending on the type of Codepad you have. The “Power” LED (light) will be “on” when power is working correctly. This LED flashes when the battery is low or on battery failure. On a TouchNav keypad, the screen will display text describing any alerts including power issues. When you arm or disarm the alarm your codepad will beep several times if there is an AC power failure or the battery is in a low power or failed state. If the battery and AC power both fail together the alarm will turn off instantly without warning. In this case, when AC or battery is restored, the above warnings will resume.
