Question

What is the danger of overcharging a battery?

Answer 1

alternator that has an internal voltage regulator. The voltage regulator supplies a controlled electrical charge to the battery while the vehicle is running. If the voltage regulator fails, an uncontrolled electrical charge to the battery can occur which will overcharge the battery every time the vehicle is running. Another way to overcharge the car battery is human error. Using a battery charger without properly knowing how can also overcharge a battery. Incorrect volts or high amp settings on a charger can overheat the battery or charge it too quickly, becoming ineffectual for the intended purpose. Leaving an unattended charger on for too long is another human error
