A car battery is 12.6v. Suppose you test a battery, you will not get to read 12 volts. In fact, if the reading tells you the 12V car battery voltage chart, the battery is considered more or less vacant. The best way to check a battery’s lifespan is to use a multimeter. The devices may be expensive but work great.
So what next? How many volts is a car battery while running?
A fully charged battery reads around 12.4-12.6v especially when the engine is not running. With a running engine, you will hardly get a reading of 13.7-14.7v. If the measures go beyond this, it starts to give bad results.
Battery is boosted to the high level according to the alternator.
How To Test Your Car Battery’s Voltage?
If you want to know the correct voltage of the battery, you must have the correct knowledge about the voltage and its death. At what voltage is a car battery dead?

- Quick, easy and accurate reading
- Use a multimeter to measure the engine and it battery
- Touch the terminals that are negative and are made up with black lead
- Switch them onto the opposite terminals
