If you are happy with the overall condition of the battery it is time to start the tests with the multimeter. When testing a battery you should test both the level of voltage and also the level of current that the battery is supplying.
Turn the switch or dial to the voltage (V) setting. If your battery is a direct current (DC) power source, set the multimeter to the appropriate DC voltage range. Check the battery label for its voltage rating and adjust the multimeter accordingly to ensure an accurate measurement. Now it’s time to connect the battery leads to the multimeter.
The voltage readings on the multimeter can provide an indication of the battery’s charge level and overall condition. A voltage reading close to the battery’s rated voltage indicates the battery is still in good condition, while a significantly lower reading suggests the battery may be weak or discharged. What is a multimeter?
Using a multimeter, you can test the battery voltage to determine if it’s within the normal range. Turn off your vehicle and set the multimeter to the voltage setting. Connect the red lead to the positive terminal of the battery and the black lead to the negative terminal. Check the reading on the multimeter.
For example, if you are testing a 9-volt battery, you can select a voltage range of 20 volts or higher. This will ensure that the multimeter can handle the voltage without any issues. If you are unsure of the battery’s voltage or simply want a more convenient option, you can use the multimeter’s auto range feature.
Turn the dial to the DC voltage mode. Select a range higher than the battery’s voltage if the multimeter is not auto-ranging. Attach the red probe to the positive terminal. Attach the black probe to the negative terminal. Look at the digital display for the voltage reading. Ensure the reading is stable before recording the value.
