Most drivers focus on car maintenance during winter, but the summer heat can be just as damaging to your car’s 12V battery.
Mark Poole, Sales Manager at CTEK explains why…
-
Summer Heat Weakens Batteries: Unlike the cold, hot weather accelerates the battery’s discharge rate. At 27°C, a battery loses 4% charge per week, compared to just 3% per month at 18°C. Mark explains, “Heat gives you a false sense of security… the battery may still start the vehicle, but it’s becoming discharged.” This hidden weakness can cause a sudden flat battery when temperatures drop.
-
Heat Damages Batteries Internally: High temperatures cause the water in the battery’s electrolyte fluid to evaporate. This weakens the battery’s ability to hold a charge and can lead to corrosion and crystal formation on the battery plates, permanently reducing its lifespan.
-
Maintaining Voltage is Key: Regardless of the season, keeping your battery’s voltage above 12.4V is crucial. If it falls below this level, a process called sulphation occurs, where crystals build up on the plates, further reducing battery capacity.
So, how can you protect your battery during the summer? Here are some tips:
-
Regular Charging is Essential: Even in warm weather, consistent charging with a proper charger helps maintain battery health and prevent hidden damage.
-
Avoid Overcharging in Hot Weather: Charging a battery at high temperatures can cause the fluid to boil, rendering it unusable. If the weather is above 25°C, use a charger with a lower voltage setting.
-
Use a Safe and Easy Charger: The CTEK CS ONE charger simplifies the process. Its APTO™ technology automatically detects the battery type and delivers a customized charging program. Plus, the polarity-free clamps eliminate the risk of incorrect connections and sparking.
By following these tips and using the right tools like the CTEK CS ONE charger, you can ensure your car battery stays healthy and starts your engine reliably all summer long.
