Standard charging: the battery is first charged to 4.2V with a constant current of 0.5C5A (1.5A), and then charged with a constant voltage of 4.2V until the current decreases to 0.01C5A when the charging current gradually decreases. The charging time is about 3 hours. There should be no permanent damage to the rechargeable battery within 0~45°C.

Standard discharge: After a fully charged 18500 battery is placed at an ambient temperature of 20±5°C for 30 minutes, it is discharged to 6.0V at a constant current of 0.2C5A, and the discharge time is about 5 hours. Therefore, it is suitable to choose a 4.2V/1A lithium battery charger.
