Should the Battery Be Replaced in Winter or Summer?
2 Answers
It is recommended to replace the battery in winter. Below is relevant information about car batteries: 1. Working Principle: During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, lead metal acts as the negative electrode, undergoing oxidation and converting into lead sulfate; lead dioxide serves as the positive electrode, undergoing reduction and converting into lead sulfate. 2. Battery Maintenance: Avoid leaving the car parked in open parking lots for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. Car batteries should be charged regularly. A battery left unused for a long time will gradually self-discharge until it becomes unusable. Therefore, start the car periodically to charge the battery.
I usually drive to and from work, but my car battery often has issues in winter. When it's cold, starting the car is particularly difficult, and several times it almost wouldn't start, forcing me to call a tow truck. Battery performance drops significantly in low temperatures because the chemical reactions slow down, leading to insufficient power supply. In summer, while there are fewer problems, high temperatures can accelerate the evaporation of the electrolyte, speeding up aging. So, I think it's best to replace the battery in autumn when the weather is neither too cold nor too hot, preparing it just right for winter. Car batteries generally last 3-5 years, so don't wait until winter to rush a replacement. You can use a simple battery tester to check the voltage; if it's below 12 volts, replace it in advance. This saves you from being stranded in the cold and also saves money and hassle. Regular maintenance is crucial; even a quick glance at the connections during each refueling to check for looseness can extend the battery's lifespan.
