The voltage of a car battery should be between 12.2 to 12.6 volts when the engine is turned off. A fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running. With the battery charge at 75%, the voltage can drop to 12.4 volts. At 25% charge, the voltage will measure around 12 volts. By measuring the car battery ...

Learn MoreThe charging/system voltage should show 14.2 to 14.6 at all times above idle.Maybe 13.9 at night, idling, with everything turned on. A fully charged battery reads 12.6 volts, disconnected and idle for over an hour. A dead battery reads 11.9 volts under the same conditions.
Learn More"We charged up our Lithium battery to 14.2V, and the percentage of charge read 100%. Then we used our appliances for a couple of hours, ran the lights, watched a movie, and the battery was at 13.2, which read 90%. Then 30 minutes later, the inverter gave us the low voltage alarm, and everything kicked off.
Learn MoreThe battery voltage is what a voltmeter reads, or how many of those four lights are illuminated on your display. The state of charge (SOC) is what the actual storage status of your battery is, 100% being fully charged and 0% being flat dead.. The reason there''s not a simple relationship between battery voltage and state of charge is that …

Learn MoreA standard 12V battery when new will output 12.7 volts nominally. An alternator when charging the 12V system will add an additional 2.3-2.7 volts. 15.3 therefore is entirely normal to see when the engine is on. Note if your car battery is fully dead (no cells working) your car will not work.

Learn MoreYou can determine the state of charge of a 12V battery based on its voltage by referring to a battery voltage chart. Battery voltage charts describe the relation between the battery''s charge state and the voltage at which the battery runs. These battery charging voltages can range from 2.15V per cell to 2.35V per cell, depending on …

Learn MoreI am concerned about the "standing voltage" of this battery and seek input from knowledgeable forum members. My alternator output consistently reads 14.3 volts while engine is running. When I turn off engine and immediately check battery voltage, it is 12.4 to 12.2 volts (immediately after running engine).
Learn MoreI agree with the others, 14.5ish while the engine running is indicative of a healthy charging system, this is actually your alternator output voltage not the battery. 12.5 when the motor is off is also normal, a fully charged 12V battery should read 12.5-12.7V. Dropping to 11.5 under load (during cranking) is also very normal.
Learn MoreResting battery voltage should be 12.7-12.8 so it could be your battery as well. Get both checked at the dealer. Also, it''s possible the vehicle sat for a long time on the lot and had a dead battery so they jumped it.
