  • Charging current should be less than maximum charge current specified in the Product Specification, Charging current bigger than recommended current may damage the battery;    
  • Discharging current should be less than maximum discharge current specified in the Product Specification;Discharging current bigger than recommended current may damage the battery;  
  • It should be noted that the cell would be possible to be at a over-discharged state by its self-discharge characteristics in case the cell is not used for long time.
  • In order to prevent over-discharging, the cell shall be charged periodically to maintain between 13.2V and 13.6V (2month one cycle),Over-discharging may causes loss of cell performance, characteristics, or battery functions;  
  • Please charge the battery within 12 hours after use;    
  • Battery storage environment follow the above conditions and in standard atmosphere, should be without strong magnet, no power, no static;  
  • Do not reverse the polarity of the battery pack for any reason;
