Fritz Posted December 29, 2021 Share Posted December 29, 2021 The Lithionics batteries come with a heating pad underneath the batteries. There is a switch in the battery compartment that turns the heating pad on or off. When turned on, the heating pad comes on when the temperature falls to 35°F. It goes off when the ambient temperature reaches 45°F. This is only necessary to charge the battery, and if there is a charging source available (i.e., shore power, solar, or generator). The batteries do not need a heating pad to discharge (e.g., turn on lights, etc.), even when the temperature is below 35°F. 3 3 2021 Oliver LE2 Ram 2500 diesel Link to comment Share on other sites More sharing options...
