They cause bigger problems that finish up damaging the battery beyond repair. Bad battery reading during the free battery check. There could be a condition when one or 2 of them are bad and not others. It is not accurate to assume that because a battery is discharged, the battery itself is bad. Many bad batteries will appear to have full voltage, but when it comes to holding that voltage under load, the battery reveals it is bad. When the engine is running, this measurement should be 13.7 to 14.7 volts. A battery that has a low state of charge may still be good after it is recharged. We’re going to disconnect the negative terminal on the battery. When you look at the battery of your car, you will see it has 5 or 6 cells in it. Leave the car overnight (preferably longer) and test before you start the car in the morning to get an accurate gauge of the battery's health. Any automotive repair shop or even some auto parts stores can load test a battery for you. However, the associate told me it was a good sign that the system showed my battery was holding a 100% charge. This is necessary because the test is dependent on the vehicle cranking, but not starting. Yes, it could test out okay and still have problems.
