How Do You Check A Battery With A Voltmeter. You can only make a guestimate. It should read 6 volts if the battery.
The best way to test the voltage of both AGM and LiFePO4 batteries is to take 5 readings. The first test with your multimeter will measure DC voltage indicated with a solid line and a dashed line above a letter V. The wavy line after a V is AC alternating current voltage and is.
After that connect the negative voltmeter lead to the negative battery terminal following the same steps you did for the positive end.
You would need to connect the probes to the battery terminals. Set the dial to 20 which will allow you to accurately measure between 0-20 Volts. Simple steps to check a car battery with a multimeter. The next thing to do is to adjust the multimeter to a direct current of 20 volts.
