What Is The Battery Voltage For A Car. If your cars performance isnt up to the mark then a low voltage battery may be the reason for it. Lets compare for a moment the Tesla Model 3 and the Porsche Taycan.
I have seen a 24 volt battery. 1245-1254 volts means you have a 75 charge 1224-1229 is 50 charged and 1199-1206 volts is 25 charged. A fully charged car battery voltage without being plugged into an external device ranges from 137 to 147 volts.
Once the vehicle is running this measurement will be slightly higher.
A fully charged car battery voltage should be 126v or above this is with the engine off. With the engine off you should get a reading of 126 volts. View the most popular hydrometer on amzn. The colder the temperature is the higher the charging voltage as to be over a defined temperature range of -40 to 125C.
