If you’ve ever been the victim of a dead car battery you know that they die at the most inconvenient of times. Whether it’s on your way to the airport, work or picking up your kids from school it is always a pain. If you have recently noticed your car not starting consistently, it could mean that your battery is close to dead. If you see the symptoms of a dead battery in your own car you should try to figure out why it is happening. Here are some of the most common reasons for a dead car battery.
1. Human Error
Mistakes happen, especially when you’re tired or very busy. Sometimes that’s the reason why you’re car’s battery is dead is you left the headlights on or didn't completely close the trunk. Overnight, these can cause drained battery which will prevent your car from starting the next day.
2. Parasitic Drain
There are some components in your vehicle that continues to run even after the key is turned off. That where parasitic drain happens. Although it’s completely normal for your battery to deliver enough energy to maintain things like clock or security alarm, it may exceed what’s normal and deplete the battery when electric problem happens at the same time. In this case, it would be best to take your ride to car repair shop to stop the problem from getting worst and get it fixed.
3. Bad Charging
If your battery drains even while you’re driving, there’s a fair chance that your charging system isn’t working properly. In this case, it wouldn’t be a surprise if you end up stranded on the road with a drained car battery because 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. Don’t let this issue lead to an even bigger one; make sure to seek car servicing here in Singapore right away as soon as this happens.
4. Defective Alternator Diode
A car alternator recharges the battery and powers certain electrical systems. If your alternator has 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.
5. Old Battery
Sometimes your car’s battery drains way to fast is because it has simply run its course. Many people don’t pay attention to the lifespan of batteries until it’s too late. Typically, they last for three to five years. If you find that it’s not holding a charge as well as it should be and it is in this age range, it is likely that it is time to invest in a new one.
