How does heat affect the car battery?
21 August 2024
As summer heats up, it’s not just our bodies that need extra care—your vehicle’s battery requires special attention to stay in top shape. High temperatures and long road trips can put extra strain on your battery, so understanding its unique needs during the summer is crucial. Fortunately, the CTEK CS ONE smart battery charger is here to help keep your battery healthy, no matter how hot it gets.
The impact of heat on battery performance
Contrary to popular belief, warm weather can actually shorten your battery's life. High temperatures accelerate the chemical reactions inside a 12V battery, leading to faster evaporation of the electrolyte and increased internal corrosion. This speeds up the aging process and can cause your battery to fail unexpectedly.
In fact, batteries tend to last longer in colder climates because cooler temperatures slow down the chemical reactions that contribute to self-discharge and degradation. For example, a battery stored at 27°C loses 4% of its charge per week, but at 18°C, it discharges just 3% per month. With higher heat comes a greater need for consistent battery maintenance.
The danger of discharged batteries in summer
During the winter, many people proactively charge their vehicle batteries to prevent them from being discharged and causing starting issues. But in summer, a discharged battery may still allow your car to start, giving the false impression that everything is fine. When the battery voltage falls below 12.4V, sulphation begins—a process that can permanently damage the battery. By the time you notice, it could be too late.
Why CTEK’s CS ONE Is Essential for Summer Battery Care
To keep your battery performing reliably during summer, the CTEK CS ONE smart charger is the perfect solution. Here’s why:
