Extend Battery Life for Almost 2 Weeks!
Get up to 2 weeks of back-up battery power with the 6 "D" cell battery holder. This carriage plugs directly into the 9V back-up battery connection on the back of any FreezeAlarm or WaterAlarm. Even when the unit is calling out continuously, every 15 minutes, you'll see almost 2 weeks of battery power from this handy back-up battery device.
This battery carriage REPLACES the use of a 9-volt battery. The carriage requires 6 "D" cell batteries instead of a single 9-volt.
