how many volts is a charged car battery
I had boosted and jump started my battery over 30 times I knew it wasnt the alternator because in the 90s they didnt have the regulator in the alternator and if it was the Alternator the car would run dead on the road. The ideal car battery voltage with the engine running is between 137 and 147V.

The battery should maintain a voltage of 72 volts 12-volt battery under conditions of -18C for the.
. When the batterys voltage drops even a small amount it. Fully charged car batteries usually measure at around 126 volts or above with some instances of your car battery showing 13 volts. When the battery is fully charged and the engine is ON the voltage is from 141 to 148 Volts.
I will be explaining in an upcoming post how to determine series-parallel vs series configurations. A fully charged battery should read 126 volts or more with the engine off. Each battery has six cells each with 21 volts at full charge.
When the engine is running and functioning correctly the car battery will fluctuate between 137 and 147 volts. Measuring your car batterys voltage can be a great way to determine how charged your battery might be. 111V Li-Ion Battery 36V Li-Ion voltage 3 Cells Actually 6 cells this is a series-parallel configuration.
Engineers measure the power created by a typical car battery in Cold Cranking Amps. Cold Cranking Amps is the measurement of how much current a charged battery can provide. What had happened was my Volt Regulator that regulates how many volts run through your car went bad.
The standard automotive battery in todays vehicles is a 12-volt battery. It can drop to 121 Volts when the charge is 50. One way is to test the voltage of the battery under load for example with the headlights on.
With the engine off you should get a reading of 126 volts. Usually they measure the current over a period of 30 seconds. If the battery isnt fully charged it will diminish to 124V at 75 12V when its only.
96V Ni-MH Battery 12V Ni-MH voltage 8 Cells Laptop Battery. A car battery is considered fully charged at 126 volts or higher. If you prefer to learn more about car battery voltage charts you will turn to our writing.
Testing the capacity of the battery with a voltmeter is more difficult.
