Heat is one of the biggest reasons this happens, and California weather can be tough on batteries. Long sunny days, hot pavement, stop-and-go traffic, and high under-hood temperatures all create the kind of stress that can shorten battery life and, in some cases, lead to swelling. Why Heat Is So Hard On Car Batteries A car battery works through a chemical reaction. Heat speeds that reaction up, which might sound helpful at first, but it actually causes the battery to age faster. High temperatures can increase internal pressure, dry out internal components, and cause the battery to lose capacity sooner than expected. Cold weather gets blamed for many battery failures because it makes weak ba ... read more
