Alarm batteries of this type are typically used in home alarm systems, fire alarms, security alarms, medical monitoring alarms, car alarms and business alarms.  Alarm batteries are used for back-up power in case of power outages or power surges.  A fully charged and maintained alarm system battery can give you piece of mind that your alarm system if fully functional even without power.  Your main alarm system back-up battery can typically be found in a battery panel located on the wall or in a battery bank possibly in a closet.  Remember, if you have a wireless alarm system you may also have batteries to maintain in your remote key fob, motion sensors, strobe lights, sirens, transmitters or other devices.  Other places to find alarm system batteries may be in back up lighting and fire and smoke sensors.

Alerts and Warnings

If your application runs on multiple batteries, make sure to replace all of them at the same time or you will dramatically reduce the lifespan of the new batteries by mixing them with older batteries.

You have to install your replacement batteries in the same original configuration they came out and are required to use your existing hardware and cables to reconnect the replacement batteries when applicable.

It is your responsibility to verify the battery or batteries being ordered match the battery or batteries in your application prior to placing your order. Please check your:

  • existing battery dimensions (Length x Width x Height)
  • quantity needed to replace all batteries
  • voltage and amp hour requirements

Manufacturers may change requirements without notice. BatteryGuy is not responsible for incorrect orders - if you need help, please contact us.
