What Should A Good 12v Battery Read. The car was left sitting overnight. Just after charging with charger disconnected 14 volts and after resting for a few days about 126 volts.
I read on PriusChat that it might be the 12v battery so I decided to check the voltage readings with a multimeter. The ideal car battery voltage with the engine running is between 137 and 147V. How many volts should a good 12 volt battery read.
It allows no access to check the level of battery fluid inside.
I had my battery out over the weekend and it reads 1175 volts. It allows no access to check the level of battery fluid inside. If the battery isnt fully charged it will diminish to 124V at 75 12V when its only operating at 25 and down to 119V when its completely discharged. How many volts should a good 12 volt battery read.
