18500 lithium battery, 18500 lithium battery manufacturer
The 18500 lithium battery definition rule is: 18500 battery diameter is 18mm length 50mm, cylindrical battery. 18500 lithium battery parameters: voltage: 3.6V (conventional universal battery, for electronic products, low-power electrical equipment, maximum 1C discharge. Can change the discharge conditions according to the situation); 3.2V (power battery can be customized according to the situation) Charging parameters: 4.2 V
The minimum discharge termination voltage is generally: 2.75V, the maximum charge termination voltage: 4.20V; capacity: 3.6V lithium cobaltate technology is now 1900AMH; diameter: 18±0.2mm

Working temperature: 0~45°C (charge), -20~60°C (discharge)
Battery charging: Charging limit voltage: 8.4V Charging current: 750mA (standard), 1500mA (maximum)
Battery discharge: discharge cut-off voltage: 5.5V discharge current: 300mA (standard), 1500mA (maximum)
18500 battery charger selection:
Standard charging: The battery is first charged to 4.2V with a constant current of 0.5C5A (1.5A). When the charging current is gradually reduced, the current is reduced to 0.01C5A with a constant voltage of 4.2V, and the charging time is about 3 hours. There should be no permanent damage to the rechargeable battery at 0~45°C.
Standard discharge: The fully charged 18500 battery is placed in an ambient temperature of 20 ± 5 ° C for 30 minutes, discharged at a constant current of 0.2 C5A to 6.0 V, and the discharge time is approximately 5 hours. Therefore, it is suitable to choose the 4.2V/1A lithium battery charger.
18500 battery use:
The 18500 battery is widely used in cylindrical lithium batteries for electronic cigarettes, toys, security, charging treasures, digital products, and automotive electronics.
