Your car battery is charged about 25 or less. A typical car battery will drain in 2-3 weeks and be unable to start your car due to the parasitic draw from the cars electronics. 118V or lower.
Follow The 12V Battery Voltage Chart. Open circuit voltage is the voltage of the battery with no load or disconnected from any circuit. Battery voltage reacts highly to charging and discharging.
Once that reaches 12V or below that power unit is considered dead. It isnt recommended to use a charger with 10 amps or more on a car battery. AutoZone Has You Covered at Americas 1 Battery Destination.
A good battery should be between 124 to 126v at rest it will drop some if any accesories are on lights radio phone or gps chargers flashers etc if you have an automotive voltageamperage tester available you can do a load test on the battery hook it up and load it by 12 the cca rating of the battery for 15 seconds if it drops below 10v its time for a new battery. Ideally you should never let your power source reach below 50 SOC meaning that you should keep it at 121V or higher looking at the chart above. A reading of 125 volts shows that your battery is healthy and 90 charged.
With experience one can accurately determine state of charge using a voltmeter. Set your meter to dc volts. For more info see the open-circuit voltage chart above.
If a fully charged 12-volt AGM battery is connected to a load its voltage may be anywhere between 1175V and 129V depending on how much current is being drawn from the battery. High Cca Agm 12v 60ah Start Stop Battery Car Engine Starting Battery Car Battery Car Engine Car State Of Charge Chart Combined Battery Bank Battery Charge Battery Pin By John Addington On Batteries Periodic Table Amazon Com Acdelco Acdb24r Advantage Agm Automotive Bci Group 51 Battery Automotive Deep Cycle Battery Acdelco Car Battery.

Car battery voltage chart state of charge. It is considered discharged at 1239 volts or less. This type of battery is intended for a commercial vehicle and has dimensions of 2075 x 875 x 98 inches.
Another example is a 4D group. Use a voltmeter to measure the open circuit voltage of the battery see car battery voltage chart. 12 Volt Lead Acid Battery State of Charge SOC vs.
An example of a BCI group number is 94R. When a voltmeter shows a low voltage reading it indicates that the chemical reaction of the battery isnt up to the mark. This is important to know when gauging how healthy your battery is.
Use a voltmeter to measure the open circuit voltage of the battery see car battery voltage chart. A car battery is considered fully charged at 126 volts or higher. 1270 1285 1280 75.
Its posts are located on the top and the right post is the positive terminal. Dont charge the battery before you test the open circuit voltage. When the batterys voltage drops even a small amount it makes a big difference in its performance.
