What causes a car battery to fail?

In Batteryby Steves Auto Repair and Tire

Many factors can cause a car battery to fail.

Here are a few reasons:

  • Charging system: Charging systems that aren’t working correctly can cause batteries to die. If your vehicle’s tensioners are worn out, or if any belts are loose they can cause the alternator to stop functioning.
  • Corrosion: Corrosion can build up on the battery terminals when battery acid combines with other substances underneath the hood of your vehicle. You can prevent corrosion by checking a battery’s water levels and cleaning the terminals and cables. You can use anti-corrosion pads underneath the battery terminals. Learn about other ways to maintain your car battery.
  • Electronics in Your Vehicle: Vehicles have clocks, computers, alarm systems and electronic modules. If you leave your car sitting for two to four weeks, the electronic can drain your battery. If you’re going to be gone for a while, you can use a battery maintainer that will help it stay charged. You can also have a friend come by and start your car. If your vehicle sits outside, you may want to invest in solar panels that plug in.
  • Leaving your headlights or dome lights: Leaving your headlights and dome lights on drains the car battery. If you’re going to leave your vehicle unattended for long periods of time, make sure these lights are off.
  • Very hot or cold seasons: If you have an old or weak battery, it could die during the winter or summer. Batteries typically go bad during warmer months, because they don’t perform well in the heat. If you live in an area that has extreme hot or cold weather conditions, you need a batter that has more reserve power. They’re going to cost more money, but you should choose a quality battery that has more reserve and is manufactured better over a cheap battery.
  • Weak battery: It’s important to take care of your battery. Those that aren’t maintained properly can weaken more quickly.
