Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.
To perform a voltage test, you will need a multimeter. Here’s how to do it: Fully charge the battery. Set your multimeter to measure DC voltage. Touch the positive and negative probes of the multimeter to the corresponding terminals on the battery. Read the voltage displayed on the multimeter.
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. Adjust the range slightly higher than the battery’s nominal voltage. For example, set it to 10V if you’re testing a 3.7V battery.
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.
Take note of the voltage reading displayed on the multimeter. If the voltage reading matches the manufacturer's specifications or is close to the labeled voltage, the battery is in good condition. If the voltage reading is significantly lower than the labeled voltage, the battery may be discharged and in need of recharging.
Set the multimeter to measure DC voltage. Connect the multimeter probes to the positive and negative terminals of the lithium-ion battery. Check the voltage reading. A fully charged battery should read around 4.2V. A significantly lower reading may indicate a discharged or damaged battery.
