With the sweltering East Tennessee summer fading into crisp autumn air, most of us are thinking about changing leaves, football, and upcoming holidays like Halloween and Thanksgiving. But there’s one crucial piece of fall preparation that often gets overlooked: your vehicle's battery.

If you want to avoid being stranded with a vehicle that won't start on a chilly morning, fall is the absolute best time to have your battery tested. Here’s why.

The Invisible Damage of Summer Heat

While cold weather is famous for killing batteries, the real damage actually happens during the summer. A hot summer and the wear of elevation changes in navigating the regional terrain accelerate corrosion inside your battery and evaporate the vital liquids it needs to hold a charge. Your battery might survive the summer, but it comes out of the season severely weakened.

Cold Weather Reveals the Weakness

When fall arrives and temperatures drop, your engine requires more power to start because the motor oil thickens. At the same time, the cold weather naturally reduces your battery's output capacity. If your battery was weakened by the summer heat, a brisk fall morning might be all it takes to push it over the edge.
