A fully charged battery will read 12.6 volts with the engine not running. It will read 12.4 at 75% charge, 12.2 at 50% charge, and 12 volts at 25% charge. With the engine running at idle you should read 13.5 to 15.5 volts. Any lower or higher and the alternator may be defective.
What voltage battery are you referring to? An automobile battery is 12 volts and a fully charged auto battery should read 12.6 volts.
Automotive Battery VoltageMost automotive batteries are 12 volts DC (Direct Current].
12 volt of an ordinary inverter battery
Automobile battery is 12 volts. If it is fully charged you should actually read 12.6 volts.
when in good working condition an automotive battery should supply between 12.6 and 13.8 volts
Yes, a van battery can be used in an automobile, IF if will physically fit in the auto's battery holder tray, is the same voltage, and can be properly secured to prevent falling out of the battery tray.
Normal voltage, checking at the battery or alternator should be in the 14 range.
Some can be, and some are run by electricity. They all run on electricity. But some run on DC battery voltage and some run on AC household voltage. Some can even run on DC or AC voltage. All automobile radios run on DC battery voltage.
The cause is the voltage regulator within the alternator (working normal). When the voltage higher it is charging the battery like after you start your car or have the headlights and wipers on. The voltage regulator keeps your battery charged up. In order to charge the battery, voltage must be higher than battery voltage.
dc - the voltage is a constant 12 volts nominally in a normal car battery.
A short to voltage is when a wire that should not have battery voltage has battery voltage. This would happen if a wire had rubbed through another wire. The other cause would be an electrical component failing and sending voltage down a wire that it shouldn't. NOTE: Shorts to voltage are very uncommon. I specialize in electrical automotive repair, and I can not even recall one time I have seen a short to voltage.
With normal battery voltage, pull the fuse to it, wait 10 seconds, then plug the fuse back in. The computer, with normal voltage, will "re-boot" properly.
