Set Your Meter To Dc Volts.

When the engine is running, this measurement should be 13.7 to 14.7 volts. This is known as “resting voltage.” when the engine is running, battery voltage will typically rise to 13.5 to 14.5 volts. This is used on both starting and deep cycle batteries. Touch one probe to the positive terminal and the other to the opposite terminal.

If The Battery Isn’t Fully Charged, It Will Diminish To 12.4V At 75%, 12V When It’s Only Operating At 25%, And Down To 11.9V When It’s Completely Discharged.

The chart typically includes voltage ranges for different battery states, such as fully charged, charged, and discharged. However, as you approach the yellow and red zones, performance may start to decline rapidly. To interpret the chart, you should compare the voltage reading of your battery with the voltage ranges. Lead acid battery voltage curves vary greatly based on variables like temperature, discharge rate and battery type (e.g.

Is 12.2 Volts Ok For Car Battery?

Your battery is healthy and fully charged. With the engine off, you should get a reading of 12.6 volts. Web a fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running. Understanding the battery voltage lets you comprehend the ideal voltage to charge or discharge the battery.
