The ideal car battery voltage range will provide you with a relevant interval according to which you can measure precisely what the voltage says about the battery’s current charge. A perfect voltage (without any devices or electronic systems plugged in) is between 13.7 and 14.7V.
Battery Testing & Maintenance. Overview; Testing & Voltage; Battery Maintenance; Seasonal Care; Battery Storage; Car Battery Testing & Voltage. It’s important to test your battery and electrical system regularly, not just when it’s starting to show signs of weakness.
Car battery voltage 12 volts is the standard automotive battery in today’s vehicle and each of the battery has 6 cells with a voltage of 2.1. A fully charged car battery has 12.6 volts.
A specific gravity of 1.269 means that the battery is fully charged. A reading of 1.229 indicates a 75% charge, 1.194 is a 50% charge, and 1.159 is 25% charged. 1.124 means you have a dead battery. Performance and capacity load test. This type of car battery test measures the ability of the battery to produce current.
Re: 12v. car batteries ... resting voltage ? When to replace ? I have found batteries last 3.5-7 years depending on how many times you forget to turn your lights off and kill the battery dead etc which can weaken it more.

To check a car battery, turn off the ignition and pop your vehicle's hood. Hook up a voltmeter to the car's battery by connecting the red lead to the positive terminal and the black lead to the negative terminal. ... "The voltage numbers helped. My car battery is at 2.3 volts after sitting in the garage for a month, and this pretty well ...
An automotive battery is a rechargeable battery that supplies electrical current to a motor vehicle. Its main purpose is to feed the starter , which starts the engine . Once the engine is running, power for the car's electrical systems is supplied by the alternator .
A fully charged 12 volt automobile battery will read 12.6 volts with a digital volt meter. It will read 12.4 at 75% charge, 12.2 volts at 50% charge and 12 volts at 25% charge ….
After charging the battery or jump starting the car, connect the voltmeter to the battery the same as before and not the charging voltage. A charging system that is operating normally should produce about 13.8 to 14.3 or more volts at idle.
