Not sure what kind of replacement battery your wireless device takes?

If you still can't figure out what batteries you need or if you don't see the correct device, please email us or give us a call at the office and we will be glad to help you out.   You should be able to find any of these batteries at your local Wal-Mart, Sam's Club, Costco, etc.

If you need a back up battery, you will only be able to get it from us.   Security & Fire panels that use 12 Volt batteries use different amp. hours depending on how many devices your system uses.   Please contact our office to determine which one you need.
