It’s best to bring your car in for a professional inspection so you can address the problem and make the necessary repairs. - Source: Internet
  • First things first, knowing a battery cell is dead is of no more use to you than knowing that the battery won’t hold a 12.6 volt charge, because you can’t fix it. So, a test of the resting voltage is just as effective a diagnosis. - Source: Internet
  • The second cheapest component in the entire charging system next to the cables is the belt, so let’s look at that next. For decades now, cars have used serpentine belts with idler pulleys that maintain tension. If the belt is squeaking or showing signs of slippage, it might not be allowing the alternator to work the way it should. If the belt hasn’t been changed and it looks cracked, it’s time to replace it anyway. - Source: Internet
  • A dead car battery may catch you by surprise. The good news is that there are several ways to avoid draining the battery. Sure, it’s always a good idea to keep your jumper cables around, but you may be wondering what can cause a battery to drain when the car is off. - Source: Internet
  • Batteries are commonly located in the engine bay to one side of the engine. If the battery is not immediately obvious when you open the hood, consult the owner’s manual. In modern cars, the battery will often have a plastic cover which will unclip, hinge up, or occasionally require removing with a few bolts or screws. There may also be a red cover over the positive (+) terminal that will lift off or snap open, too. - Source: Internet
  • If you prefer using the alternator, start by charging the engine with a pair of jumper cables. Next, drive the vehicle for less than 30 minutes. You can even charge the battery by removing it from the vehicle, and taking it to an auto parts store. - Source: Internet
  • To perform a voltage drop test of the cables and terminals, touch one probe to the battery post, and then the other to the terminal. It should read at or near zero.
