Thermal Considerations of Lithium-Ion and Lead-Acid Batteries
Low temperatures reduce the output of a lead-acid battery, but real damage is done with increasing temperature. For example, a lead-acid battery that is expected to last for 10 years at 77°F, will only last 5 years if it is operated at 92°F, and just a year and a half if kept in a desert climate at a temperature of 106°F.
