Extreme temperatures can impact a car battery. Cold weather, especially temperatures below 32°F (0°C), can reduce battery efficiency and sometimes cause it to fail. Conversely, extreme heat, above 100°F (37.7°C), can also damage the battery's internal components. To protect your battery, consider using an insulated battery blanket in winter and ensuring proper ventilation during summer.
