Low temperatures can negatively affect the performance of vehicle batteries, causing reduced efficiency and unexpected failures. Drivers often face difficulties starting their engines on cold days, a phenomenon mainly due to the natural effects of cold weather on batteries.
Batteries rely on chemical reactions to generate energy. In low temperatures, these reactions slow down, reducing the battery’s ability to deliver full power. For instance, at -18°C, the available power of a fully charged battery can decrease by up to 50%.
Reduced cranking power: The vehicle requires more energy to start.
Delayed engine startup: The engine takes longer to start than usual.
Reduced range in electric vehicles (EVs): EV batteries lose capacity, decreasing the vehicle’s range.
Battery health check: Perform regular checks to ensure the battery is in good condition.
Use of maintenance chargers: Trickle chargers keep the battery fully charged without overloading.
Cleaning terminals: Corrosion and dirt reduce conductivity.
Store in protected spaces: If possible, keep the vehicle in a garage to limit exposure to the cold.
Check fluid levels: For lead-acid batteries, ensure the fluid levels are adequate.
Frequent vehicle use: If the vehicle remains unused for long periods, start it regularly.
Signs like difficulty starting, frequent voltage drops, or visible wear suggest it might be time to replace the battery. Invest in modern technologies like AGM or EFB batteries, which perform better in extreme temperatures.
Cold temperatures don’t have to catch you off guard. With proper care and regular maintenance, you can ensure your vehicle battery operates smoothly, even on the coldest winter days.
