To assess the health of individual lithium battery cells, you need to measure the voltage of each cell. Connect the multimeter to each cell and set it to measure voltage (V). Connect the negative (-) lead of the multimeter to the negative (-) terminal of the cell and the positive (+) lead to the positive (+) terminal of the cell.
One of the simplest and most effective ways to gauge a lithium battery's health is by measuring its voltage. Voltage essentially tells you how “full” the battery is at that moment. Steps to Check Voltage: Set your multimeter to DC voltage mode. Look for a “V” symbol with a straight line on your multimeter's dial.
To determine if a lithium-ion battery is fully charged, you need to measure the voltage of the battery. Connect the multimeter to the battery and set it to measure voltage (V). Connect the negative (-) lead of the multimeter to the negative (-) terminal of the battery and the positive (+) lead to the positive (+) terminal of the battery.
