A fully charged car battery voltage without being plugged into an external device ranges from 13 7 to 14 7 volts.

How much voltage should a fully charged car battery have.

A meter reading of 12 2 volts or 12 0 volts will indicate a charge rate of 50 percent and 25 percent respectively. If the battery isn t fully. A voltage value of 12 7 volts and above indicates a 100 percent charged battery. A fully charged car battery voltage ranges from 13 7 to 14 7 volts it will drop to 12 4 volts.

It will drop to 12 4 volts when the charge is 75 and 12 volts when it is at 25. The ideal car battery voltage range will provide you with a relevant interval according to which you can measure precisely what the voltage says about the battery s current charge. The voltage reading of 12 4 volts will indicate that the battery is only 75 percent charged. With the engine off you should get a reading of 12 6 volts.

To get a true voltage reading of the cars battery it is important to measure the voltage after the car has been sat for a period with the engine off preferably overnight this provides you with the car battery open circuit voltage or also know as the resting voltage. There is a very big difference when a car battery drops even a small amount of voltage. When the engine is running this measurement should be 13 7 to 14 7 volts. A fully charged car battery has 12 6 volts.

12 volts is the standard automotive battery in today s vehicle and each of the battery has 6 cells with a voltage of 2 1. When a car drops for instance from 12 6 to 12 0 there will be 75 difference. When fully charged how many volts should a car battery have. Fully charged automotive batteries should measure at 12 6 volts or above.

A fully charged car battery voltage should be 12 6v or above this is with the engine off.
