18650 Lithium Battery, 18650 Lithium Battery Manufacturer

The 18650 lithium battery definition rule is: 18650 battery diameter is 18mm, length is 65mm, cylindrical battery. 18650 lithium battery parameters: voltage: 3.6V (conventional universal battery, for electronic products, low-power electrical equipment, maximum 1C discharge. Can change the discharge current 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; the capacity: 2000AMH; diameter: 18±0.2mm

18650 Lithium Battery Manufacturer

Benzo lithium battery 7.4V 2000mAh 18650 lithium battery pack design:

Battery model: 18650-2S1P/2000mAh/7.4V
Nominal voltage: 7.4V
Nominal capacity: 2000mAh (0.2C discharge to 5.5V)
Factory voltage: 7.2V~7.8V
Product size: 65×18×18mm
Internal resistance of finished product: ≤250mΩ
Shelf life: 12 months
Working temperature: 0~45°C (charge), -20~60°C (discharge)
Battery charging: Charging limit voltage: 8.4V
Battery discharge: discharge cut-off voltage: 5.5V

18650 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 18650 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.

18650 battery Applications:

The 18650 battery is widely used in cylindrical lithium batteries for electronic cigarettes, toys, irobot, charging treasures, digital products, automotive and other electronic fields.
