CAA South Central Ontario (CAA SCO) has issued a notice reminding drivers to check their car batteries this summer, due to the effect extreme heat has on their systems.
The insurer published its warning after reporting an 8% increase in car battery-related calls during the summer months.
“Many people worry about their batteries failing in the winter, but intense heat can be just as much of an issue as the bitter cold,” said CAA SCO manager of public relations Kaitlynn Furse.
According to Furse, a car battery can lose its charge 33% faster in extreme heat compared to the frigid winter. Increases in outdoor temperatures also lead to temperature increases under the hood, so an average 32°C day could mean your vehicle’s inner temperature could be closer to 60°C.
High heat can lead to structural damage, corrosion and the breakdown of the charging system, CAA said.
“Beyond monitoring and maintaining your battery, drivers should pay close attention to any sign of their car overheating to avoid finding themselves on the side of the road,” Furse added.
CAA has also warned that, during periods of high call volume, it will prioritise serving those drivers stranded on the roadside in the heat, over drivers stuck back home.
