How Many Volts is a Car Battery? (Not so simple) Smart Motorist
A fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running. With the battery charge at 75%, the voltage can drop to 12.4 volts. Web if the car is running, the battery may display a voltage of 13.9 to 14.8 volts, because of the energy being contributed by the alternator. If the battery isn’t fully charged, it will diminish to 12.4v at 75%, 12v when it’s only operating at 25%, and down to 11.9v when it’s completely discharged. Web the same is true when measuring battery voltage to determine if a battery has gone bad. Web so, how low are we talking? It only needs to drop down to around 10.5 volts to be considered fully discharged. Web the ideal car battery voltage with the engine running is between 13.7 and 14.7v. With the engine running, on. Web in fact, if the reading tells you 12v, your battery is more or less empty.
With the engine running, on. Web here's a chart that shows fully charged voltages on single batteries and total battery pack voltage. The voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. You should receive a reading of 12.6 volts with the engine turned off. It only needs to drop down to around 10.5 volts to be considered fully discharged. Web if the car is running, the battery may display a voltage of 13.9 to 14.8 volts, because of the energy being contributed by the alternator. If it drops down below that, the battery will become damaged due to excessive sulfation. The chart above states the voltage of a car battery may be as much as 12.7 v. If it shows anywhere in between 12.4 to 12.8, then your battery health is perfect. Web the ideal car battery voltage with the engine running is between 13.7 and 14.7v. With the engine running, on.
