CAA South Central Ontario (CAA SCO) has published a notice reminding motorists to check their vehicle batteries during the summer months. According to the insurer, batteries can become damaged due to extreme heat during summer, so drivers should keep an eye on their condition.

In a press release, CAA South Central Ontario says it observed an 8% jump in car battery-related calls during summer.

“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.

Furce adds car batteries can lose charge 33% faster when it is hot compared to during the cold months of winter. Increased temperature in the weather during summer translates to higher temperatures under the hood of a car. For example, an average 32°C summer day will mean a 60°C temperature in the engine compartment.

Batteries are affected by heat because corrosion happens more rapidly, with structural damage a common cause of problems.

“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 says in its warning that drivers with problems on the roadside will be prioritized during the summer over those with issues while at home or in a location.
