You’re late for work and rush out to your car, just to find that it won’t start. You know naturally that your Car Battery is dead. But how could this happen? There are five main causes of auto battery drain or failure.
You’ve most likely done this at least once in your life – you’ve returned home from work, tired and not by any means considering, and you’ve left your lights. Then, in the morning, you have a dead auto battery, and your auto won’t start. Most new cars will alert you in the event that you’ve left your lights on, yet might not have alerts for different parts.
Parasitic drain is because of segments in your vehicle continuing to run after the key is turned off. Some parasitic drain is ordinary – your battery delivers enough energy to keep things like your clock, your radio presets and your security alarm operational at all times. Sometimes, however parasitic drain exceeds what is normal, and can cause car battery drain.
If you’re charging system isn’t working properly, your car battery can be draining when you’re driving. On the off chance that your lights, radio, and other things are running off your alternator, your car battery will drain and you could end up with car battery failure. Then you’ll be stranded at roadside with a slowed down auto that needs a help. And even then, bad charging will drain your car’s battery.
Defective alternator diode
If your alternator has an awful diode, your battery can drain. The bad diode can even bring about the circuit to charge even when the engine is shut off. At that point you end up in the morning with a car that won’t start.
If your battery is old, it might not hold a full charge any more. If your auto isn’t starting consistently, it’s possible that your battery is simply exhausted. You should replace your battery every 4-5 years, so if your car isn’t starting consistently, and your battery is old, this should be the main thing you consider.
Expecting that the reason for the battery drain is not human mistake, you will require the help of a qualified technician who can analyze your electrical issue and figure out whether it is the battery or something else in the car electrical system.
