How Check Battery With Multimeter. This particular battery test is a way to check for battery voltage using a multimeter or a voltmeter. The multimeter battery test function allows you to measure a batterys potential.
Set the device to read DC direct current voltage. Check for volt levels on the battery. First we will measure the voltage of the battery.
Laptops commonly use volt of 96 volts 108 volts 111 volts 144 volts or 148 volts.
Check for battery drain. After doing this set the dial to 20 volts so you will be able to measure 0-20 volts. Once you have rested overnight you should take the test. Any reading of voltage below 95 volts or if the battery holds a good record for a while and steadily drops or even when it falls instantly to 0 volts then it means there is a problem and the battery.
