18650 battery charger selection:
Standard Charging: The battery is charged to 4.2V at a constant current of 0.5C5A (1.5A). When the charging current decreases gradually, it is charged to 0.01C5A at a constant voltage of 4.2V. The charging time is about 3 hours. Rechargeable batteries should not be permanently damaged at 0~45 C.
Standard Discharge: A charged 18650 battery is discharged to 6.0V at a constant current of 0.2C5A for about 5 hours after being shelved for 30 minutes at ambient temperature of 20 + 5 C. Therefore, it is suitable for 4.2V/1A lithium battery charger.
18650 battery usage:
18650 battery is a cylindrical lithium battery widely used in electronic cigarette, toys, security, rechargeable treasure, digital products, vehicle and other electronic fields.
