Lir2032 button battery is a button battery with a capacity of 40mAh and a voltage of 3.6V. The maximum discharge current of lir2032 button battery shall not exceed 40mA, and the charging current shall be 8Ma.

Difference between lir2032 button battery and CR2032 button battery:

1. The capacity of lir2032 button battery is 40mAh, and that of CR2032 button battery is 220mah;

2. The voltage of lir2032 button battery is 3.6V and CR2032 button battery is 3V;

3. The load capacity is different. Lir2032 button battery can withstand 40mA continuous discharge, most of which can be recharged by hand, such as flashlight, charger, etc., while CR2032 button battery can only withstand 5mA continuous discharge, most of which can use clock backup power supply.

Charging method of lir2032 button battery:

Find a resistor of about 1000 ohm and a 12V battery, connect the negative pole of the lir2032 button battery to the negative pole of the battery, connect the positive pole of the lir2032 button battery to the positive pole of the battery through the 1000 ohm resistance, and charge for about 6 hours continuously. It is better to combine a 4.1v10ma regulator at the positive and negative poles of the lir2032.
