You’re late for work and rush out to your car, only to find that it won’t start. The headlights are dim and the engine refuses to start. You realize that your battery is dead. But how did this happen? There are five main causes of car battery drain or failure.

Human error – You come home from work, tired and not really thinking, and left the headlights on or didn’t completely close the boot. Overnight the battery drains, and in the morning your car wont start. Many new cars alert you if you’ve left your lights on, but may not have alerts for other components.

Parasitic drain – Parasitic drain is due to components in your vehicle continuing to run after the key is turned off. Some parasitic drain is normal, your battery delivers enough energy to keep things, like your clock, radio pre-sets, and security alarm operational at all times. However, if there’s an electric problem, parasitic drain can exceed what’s normal and deplete the battery.

Bad charging – If your charging system isn’t working properly, your car battery can drain even while you’re driving. Many cars power their lights, radio, and other systems from the alternator, which can make the battery drain worse if there’s a charging problem. Then you’ll be stranded at roadside with a stalled car that needs a boost. And even then, bad charging will drain your car’s battery. A professional mechanic will be able to diagnose what’s causing a charging problem.

Defective alternator diode – A car alternator recharges the battery and powers certain electrical systems. If your alternator had a bad diode, your battery can drain. The bad diode can cause the circuit to charge even when the engine is shut off, and you end up in the morning with a car that won’t start.

Old battery – If your battery is old, it might not hold a full charge. If your car consistently won’t start, it’s possible that the battery is worn out. You should generally replace your car battery every 1-2 years. If your car isn’t starting consistently, and your battery is old, battery replacement should be the first thing you consider.

Having a battery that won’t hold a charge is frustrating, and figuring out what’s causing the problem can be tricky. Assuming that the cause of the battery drain is not human error, you will need the assistance of a qualified mechanic who can diagnose your car’s electrical problem and determine if it is the battery or something else in the electrical system.
