How Many Volt Does A Car Battery Have. The battery is not charged and could be bad if the reading is 119 volts or lower. In fact a batterys voltage should register nearer to the higher range if its working properly but different numbers may be recorded under varying conditions.
A car battery should read a minimum of 126 volts and when your engine is in operation the battery should record a voltage value within the range of 137 147 volts. In fact a batterys voltage should register nearer to the higher range if its working properly but different numbers may be recorded under varying conditions. If you dont have a multimeter to tell you the voltage of your battery you can do a test of your electrical system by starting the car and turning on the headlights.
When a car drops for instance from 126 to 120 there will be 75 difference.
One of the cars my parents owned a long time ago had a 6 volt system. Its power drops from 100 to 25. When the engine is running this measurement should be 137 to 147 volts. How many volts is a car battery.
