The car battery is a storage device, which stores energy. This supplies a current at a particular voltage (DC) to the conductive parts of the circuit. The standard car batteries in today’s vehicles are rated at 12 volts. Each battery has six cells which are 2.1 volts each. A car battery is considered fully charged at 12.6 volts. When a battery drops voltage, even by a small amount, it makes a big difference.
For instance, when a battery drops from 12.6 to 12.0 volts, its power drops from 100% to 25%! At 12.4 volts, a car battery is only 75% charged. At 12.2 volts, it’s 50% charged. A car battery is considered charged at 12.4 volts or higher. It is considered discharged when it’s at 12.39 volts or less. The current is heavily dependent on the type of battery and the resistance of the ‘load’.
