Is your car battery always dying? While many assume its cold weather that kills batteries, they are actually more adversely affected by heat. Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. That’s why it’s a good idea to check your battery as the seasons change from hotter to cooler or if you’ve been driving in a hot part of the country.

To get the most life out of a battery, be sure the electrical system is charging at the correct rate; overcharging can damage a battery as quickly as undercharging. Also, keep the top of the battery clean. Dirt becomes a conductor, which drains battery power. Further, as corrosion accumulates on battery terminals, it becomes an insulator, inhibiting current flow.
