1 Use a battery charger to maintain charge levels and keep the battery in good condition. 2  According to Kimbrough, a fully charged battery will not freeze until -76Â°F; however, a fully discharged battery could start to freeze at 32Â°F.
The recommended charge rate at low temperature is 0.3C, which is almost the same as under normal conditions. At a comfortable temperature of 20 Â° C (68 Â° F), gassing starts at 2.415V/cell, and by lowering the temperature to â20 Â° C (0 Â° F), the gassing voltage rises to 2.97V/cell.Do not freeze a lead acid battery.echargeable batteries operate in a wide temperature range but this does not give license to charge them at extreme temperatures. Extreme cold and high heat reduce charge acceptance, and the battery must be brought into moderate temperature conditions before charging.
