Electrical Characteristics

Parameter	Value
Charge Voltage	4.2V
Standard Charge Current	0.5C
Rapid Charge Current	1.0C
Max Charge Current	0.5C
Discharge Cut-off Voltage	2.5V ± 0.25V
Charging Temperature	0°C to 45°C
Discharging Temperature	0°C to 45°C
Storage Temperature	-10°C to +45°C

Charging Method

Standard charging: 0.5C CC (constant current) charge to 4.2V, then CV (constant voltage 4.2V) charge until current declines to ≤0.05C

Charging time: Standard - 2.75 hours (approx.), Rapid - 2 hours (approx.)

Safety & Testing

Drop Test: Cell withstands 1-meter drop onto concrete ground twice without fire or leakage

Application Areas

Lighting: Headlamps, emergency lights, solar flashlights, searchlights, bicycle lights, LED lighting
Outdoor Sports: Camping lights, mountain bike lights, solar emergency lights, self-defense flashlights
Consumer Electronics: Portable speakers, MP3 players, tablets, laptops, Bluetooth earphones, power banks
Home Appliances: Electric mops, vacuum cleaners, children's toys, electric shoes, electric blankets
Medical Devices and Instruments
Electric Transportation: E-bikes, electric cars, scooters, motors, trolleys
Power Tools: Electric drills, mowers
UPS and Backup Energy Systems

Voltage Comparison: 3.7V vs 3.8V Batteries

Nominal & Charging Voltage

3.7V Standard: Nominal 3.7V, Charge cut-off 4.2V

3.8V High Voltage: Nominal 3.8V, Charge cut-off 4.35V

Energy Density

High-voltage batteries provide approximately 15% higher volumetric energy density

Achieved through higher nickel content in cathode materials (NCM811/NCA)

Cycle Life

High-voltage batteries typically have shorter cycle life due to higher operating voltage

Standard-voltage batteries offer better longevity for industrial applications

Application Scenarios

3.7V: Mature technology, high safety, low cost - ideal for portable devices, Bluetooth headsets, dashcams

3.8V: Higher energy requirements - used in high-end phones, IoT terminals, medical equipment (requires 4.35V charging circuits)
