Customer ServiceConnect the negative (-) lead of the multimeter to the negative (-) terminal of the battery. Connect the positive (+) lead of the multimeter to the positive (+) terminal of the battery. Turn on the multimeter and set it to measure voltage (V). When testing a lithium battery with a multimeter, you must set the readings accordingly.
Measuring the voltage drop across a low-side current-shunt resistor is often the simplest method to determine battery/load current. Figure 2 shows an example low-side current-sensing circuit using the TLV379. The circuit in Figure 2 was designed to create a 0V-1.2V output voltage for a 0A-1A load current, i LOAD.
Lithium-ion batteries are widely used in electronics and must be tested for safety and performance. Turn the dial to the DC voltage mode. Set the range higher than the expected voltage (typically around 20V). Ensure the battery is not connected to any device. Handle the battery carefully to avoid short circuits or damage.
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.
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.
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.
