Cautions of charge & discharge:
  • Charge:
Charging current should be lower than values that recommend below. Higher current and voltage charging may cause damage to cell electrical, mechanical, safety Performance and could lead heat generation or leakage. 
(1) Batteries charger should charging with constant current and constant voltage mode; 
(2) Charging current should be lower than (or equal to )1C5A; 
(3) Temperature 0~45℃ is preferred when charging; 
(4) Charging voltage must be lower than 4.25V. 
  • discharge:
(1) Discharging current must be lower than (or equal to )2C5A;
(2) Temperature -10~60℃ is preferred when discharging; 
(3) Discharging voltage must not be lower than 2.75V.(Not including -10℃discharge )
  • Over-discharge:
It should be noted that the cell would be at an over-discharge state by its self-discharge. In order to prevent over-discharge, the cell shall be charged periodically to keeping voltage between 3.6-3.9V. Over-discharge may cause loss of cell Performance. It should be noted that the cell would not discharge till voltage lower than 2.5V.
