(3)Characteristic Curves  

 

(4) Electrical Characteristic 

Item	Standard	Test Method
Discharge Characteristics	Discharge Time: (A) 0.2C5A≥5h, (B) 1C5A≥51min	After standard charged, rest for 30min and then discharge at 0.2C5A and 1C5A to the discharge cut-off voltage respectively. Charge/discharge cycle can be conducted for 5 times before meeting the Standards(the same below).
Normal Storage	Discharge Time≥4.25h	Store for 28 days after standard charged, and then discharge at 0.2C5A to the discharge cut-off voltage.
Cycle Life	Cycles≥300	Standard charged, then conduct 0.5C5A /1 C5A cycle untill the discharge time less than 45min for two continous cycles.
Long Time Storage	Discharge Time≥4h	Standard charged, Discharge to the state of 50% capacity. Store for 12 months at room temperature. Conduct 0.2 C5A /0.2 C5A cycle for 5 times before meeting the standard.

  

(5) Notes:

11.Do not directly solder the battery and pierce the battery with a nail or other sharp objects.

12.Do not use or leave the battery at high temperature (for example, at strong direct sunlight or in a vehicle in extremely hot weather). Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.

13.Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.

14.If the battery leaks, and the electrolyte get into the eyes, do not rub the eyes, instead, rinse the eyes with clean water, and immediately seek medical attention. Otherwise, it may injure eyes.

15.If the battery gives off an odor, generates heat, becomes discolored or deformed, or in any way appear abnormal during use, recharging or storage, immediately remove it from the device or battery charger and stop using it.

16.In case the battery terminals are dirty, clean the terminals with a dry cloth before use. Otherwise performance may occur due to the poor connection with the instrument.

17.Be aware discarded batteries may cause fire or explosion, tape the battery terminals to insulate them.
