Gate Opener Battery Heater Kit
The Battery Heater helps keep gate opener batteries of FM500/502 or PRO series warm in cold climates.
This heater is recommended where outside temperatures stay below 0 degrees C or 32 degrees F for an extended period of time.
The Battery Warmer is very safe and easy to install, and it wires into the gate opener circuit board to maintain a constant temperature. It attaches directly to the gate opener's 12 Volt battery, and will prevent the battery from losing its charge in cold temperatures.
NOT for use on SOLAR charged gate openers, gate opener must be powered via 110 volt supply.
