Mighty Mule FM316 - Battery Heater Kit

  • Sale
  • Regular price $48.00


The Battery Heater helps keep gate opener batteries warm in cold climates. This heater is recommended where outside temperatures stay below 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 solar compatible.
