First set your voltmeter to 20 DC volts.
Checking the voltage can be misleading because the battery may test well based on voltage but can not hold a load. How to check battery voltage with multimeter. Connect both ends of the resistor to each of the battery terminals. To do this Move the selector dial to select DC voltage measurement.
