Chemical reactions start cars. The battery turns chemical energy into electrical energy to provide the starter with voltage and turn the engine over. It also provides power to every component within your car, including automatic windows and dashboard lights. Batteries are rechargeable and typically last three to five years with the right care. And while dead car batteries are fixable with jumper cables from the local towing service, it is a good idea to learn what causes dead batteries to save yourself time and hassle.

5 Common Causes of Dead Car Batteries

1. Doors & Trunks Left Open

Accidentally leaving car doors or the trunk open keeps the interior lights on to drain your battery. Always check the doors and trunk when you are parking your car, especially if you are not at home. You could compromise the safety of your vehicle in addition to needing towing service.

2. Leaving the Lights On

Interior lights, as well as headlights, left on cause batteries to die quickly. If your car is older and does not feature automatic light shutoffs, make checking lights a habit. Headlights, in particular, drain batteries at a fast rate.

3. Damaged Relay Switch

4. Leaving the Audio System On

Audio systems left on all day or night kill the battery. Listening to the radio or using your entertainment system to watch a movie while the car is off also drains the battery. This is because the ignition stays on despite the engine not running.

5. Alternator Issues

When an alternator needs replacing because it no longer provides electrical power, the battery must accommodate this loss. Since car batteries are designed to provide boosts rather than continuous power, a failing alternator is an easy way to kill this important part.
