This article mainly introduces the measurement methods of voltage, charging current, and discharge current of lithium batteries. It is simple and easy to learn, and can be done with just a multimeter. Let's take a look together.

1> How to measure the voltage of a battery:

The voltage of the battery can be measured using a pointer type multimeter or a digital multimeter

Method: 1. Choose the range of the multimeter (1.5V, 3V, 6V, 9V);

2. Connect the red probe to the positive pole of the battery and the black probe to the negative pole of the battery.

2> How to measure the charging and discharging currents of a battery:

Measure the current of the battery using a pointer multimeter or digital multimeter:

Method: 1. Select the mileage of the multimeter (100mA, 500mA, 1A, 5A);

2. Connect the multimeter in series in the circuit;

3. The red pen allows the current to flow in, while the black pen allows the current to flow out;

4. Electrical appliances must be connected to the circuit, and the ammeter must not be directly connected to both ends of the battery.
