It seems contradictory, but summer heat can be tougher on your vehicle and its battery than the cold grip of winter. That’s because high temperatures can zap your car’s battery by weakening its charge, and lead to structural damage and corrosion.
According to CAA South Central Ontario, a vehicle’s battery can lose its charge 33% faster in extreme heat compared to the frigid winter. Moreover, when the temperature outside reaches 32 C on a hot summer day, the temperature inside your car can hit 60 C or higher.
Car batteries are designed to last from three to five years. Getting your battery inspected by a certified technician as part of your vehicle’s routine maintenance is essential, especially if you’re planning a family road or day trip before summer winds down.
Summertime heat can trigger four problems that can deplete a gas-powered car’s lead-acid battery charge and lead to its failure, including:
Many electric vehicles (EVs) use lithium-ion batteries. They too are susceptible to high temperatures. It’s recommended to park your EV in a shaded area whenever possible, and if you use a public rapid-charging station, try to find one that’s in a shelter or opt for a slower charge. When you are powering it up in hot weather, refrain from charging it to the max on a regular basis or the battery may get too hot. That can accelerate the battery’s cell degradation, which is when lithium-ion batteries lose the capacity to recharge.
CAA offers the following tips to drivers to maximize their car’s readiness for the summer months ahead:
If you’re thinking of buying a new battery for your vehicle, start by checking your owner’s manual to ensure you purchase the right kind of battery for your car or truck. Most gas-powered vehicles use either a traditional lead-acid battery or an absorbed glass mat (AGM) battery.
And take note: you can recycle an old lead-acid car battery. Bring your discarded battery to the repair shop or retailer you purchase a new one from to dispose of it but be mindful of the safety precautions outlined in your vehicle owner’s manual if you are going to remove and transport a dead battery.
Like your vehicle and its battery, your car insurance needs attention as well. Compare insurance quotes today to find the best price for the type of coverage you need.
