Most drivers think battery problems occur primarily in winter, but summer heat can negatively impact a car’s battery even more than the bitter cold of winter. Heat and vibration are a battery’s two worst enemies leading to internal breakdown and eventual failure. While drivers cannot do much about the heat, they can make sure their battery is securely mounted in place to minimize vibration.
Another potential summer problem is faster evaporation of the battery fluid, leading to corrosion on terminals and connections. Clean any corrosive build-up from the battery terminals and cable clamps, and ensure the clamps are tight enough so they will not move.
If a car’s battery is more than three years old, it’s a good idea to have it tested by a trained technician to determine how much longer it will last.
