    A: We accept T/T and L/C.

5. Q: What is minimal rated capacity?

 A: minimal rated capacity is the capacity on 0.2 C discharge till the voltage tapered to 2.0V shall be measured  after rested for 30min then finish standard charge.


6. Q: What is internal impedance?

 A: Internal impedance is measured at AC 1KHz after 50% charge.


7. Q: What is standard charge?

 A: Charging shall consist of charging at a 0.2 C constant current rate until the cell reaches 4.20V. The cell shall then be charged at constant voltage 0f 4.20 volts while tapering the charge current Charging shall be terminat  ed when the charging current has tapered to 0.02 C. Charge time:Approx 6.0h,The cell shall demonstrate no permanent degradation when charged between 0℃ and 45℃


8. Q: What is standard discharge?
