If your car won’t start, the issue may be a dead battery. When this happens, you may need a jump start or emergency towing to move your vehicle. If you want to avoid being in this situation, you must understand how this unit works. To help you care for your vehicle’s battery, here are a few ways it can get drained.

3 Causes of Car Battery Failure

1. Age

An old battery is weak and can’t hold a full charge anymore. If your unit is older than about five years, even simple functions like the radio may quickly drain it. To avoid having to jump start your vehicle, pay attention to warning signs like clicking sounds when your car starts, or dimming headlights when you’re idle. You can also have your battery tested for its efficiency.

2. Lights Were Left On

A car battery recharges with the help of the alternator while the engine is running. When the car is off, the unit can still supply power to dome lights and headlights for a limited time. Leaving any of these lights on overnight can drain your battery, resulting in an unpleasant surprise when you get back to your car. The only way to avoid the need for a jump start or towing is to always check that both exterior and interior lights are off before walking away from your vehicle.

3. Accessories Were Used With the Engine Off

When your engine is not running, you are using up your battery’s limited charge. Accessories that cause draining include vehicle entertainment systems and digital displays that remain on when the key is in the ignition. To prevent issues, don’t stay in your car for too long with the accessories on if the vehicle isn’t running.
