Charging & discharging feature:

Standard charge(25±2℃): constant current 0.2C mA to 4.2V, constant voltage 4.2V 0.02CmA cut-off.

Fast charge(25±2℃): constant current 1.0C mA to 4.2V, constant voltage4.2V, 0.02CmA cut-off.

Standard discharge (25±2℃): constant current 0.2CmA 3.0V cut-off

Fast discharge(25±2℃): constant current 1.0CmA 3.0V cut-off

Operating temperature: charging: 0~45℃, discharging: -20°C ~ 60°C

20±5℃ is the recommended storage temperature

Safety Protection Performance:

1. Over-charge protection: At 20±5℃ conditions, after fast-charging, use an external 5V power to charge the battery and last for 24 hour, then check the appearance. No explosion, no fire, no smoking, no leakage as results.
   
   
2. Over-discharge protection: At 20±5℃ conditions, discharge battery to 2.5V
   with 0.2C constant current, then discharge with 30Ω loading for 24 hours. Check the appearance. No explosion, no fire, no smoking, no leakage as results.
   
   
3. Short-circuit protection: After fast-charging, use a cable of 0.1Ω resistance to short the battery for 24 hour. Then check the appearance. No explosion, no fire, no smoking, no leakage as results.
