Why Does Your Car Battery Keep Draining?

Top reasons your car battery is draining

Battery is the most important part of a car as it provides power to headlights, accessories and the engine. If the battery is down you won’t be able to start the engine. Here is a list of 6 major reasons that could be draining your car battery.

Things That Can Drain Your Car Battery

  • YOU LEFT YOUR HEADLIGHTS ON
    Forgetting to turn off the interior lights or leaving your car’s headlights on, will surely cause the car battery to drain. This is the most common reason that is responsible for draining the battery dead overnight. So, pay close attention to your lights.
  • TOO MANY SHORT DRIVES
    Taking a lot of short drives can cause the battery to wear out prematurely. Shutting off your vehicle after a short trip doesn’t give enough time to the alternator to recharge your battery, which shortens your car’s battery lifespan and especially if you have an older battery.
  • BATTERY CORROSION
    This is something that you cannot prevent. Battery connections can get corroded with time which prevents the charging system from topping up your battery. So it is important to regularly clean your car’s battery terminals.
  • FAULTY ALTERNATOR
    The other common mistake is not recognizing when the problem is not your battery but a damaged alternator. The basic component of the charging system is the alternator. If the alternator is not working correctly, it can’t power your battery and can deplete it even while driving.
  • OLD BATTERY
    It is advisable to change your car’s battery after every three or four years because it loses its recharging capability with time. If your battery is old, you should get it replaced as it won’t be able to hold a charge and would die eventually.
  • BAD IGNITION RELAY
    Ignition relay is responsible for providing power to the car’s ignition system. If the ignition relay is bad, it will not only cause problems in starting your vehicle but can also be responsible for draining and damaging the battery.

These are some of the most common reasons why your car battery keeps draining. So take proper precautions to keep your battery well maintained in order to avoid premature replacement of the battery.
