Monitor and record the discharge time. Connect the battery in series with the multimeter to measure the current drawn by the load. Calculate the capacity by multiplying the discharge current (in amps) by the time it took for the battery to reach its cutoff voltage.
It is measured in ampere-hours (Ah) or milliampere-hours (mAh). When examining the battery with a multimeter, one of the key measurements to check is its voltage. Voltage represents the electrical potential difference between the positive and negative terminals of the battery.
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.
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?
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.
Step-1: Ensure instrumentation is operational & properly connected to the battery for continuous monitoring of discharge voltage and current. Step-2: Measure the float voltage of the each cell/unit to ensure appropriate flotation. Step-3: Disconnect the charging current from battery.
