Why Desert Heat Is Hard on Your Car Battery
High heat speeds up the chemical reactions inside a car battery and evaporates fluid, which shortens its life. In the Las Vegas Valley, many batteries last only two to three years.
Watch for warning signs
- The engine cranks slowly when you start the car.
- Headlights look dim at idle.
- A battery warning light on the dashboard.
- White or blue crust around the terminals.
Get it tested before summer
Most auto parts stores and repair shops test batteries for free. A quick test in spring can save you from a breakdown on a 110-degree afternoon.
Park smart
Park in shade or a garage when you can, and use a windshield sunshade to keep the cabin cooler.
Carry a backup plan
Keep jumper cables or a roadside kit in the trunk, plus a tire inflator, since heat also changes tire pressure. Always carry water in the car during summer.
