Standard Charge	Charging the Battery initially with constant current at 0.5C and then with constant voltage at 58.4V till charge current declines to 0.05C.
Rated Capacity	The capacity means the discharge capacity of the Battery, which is measured with discharge current of 0.5CA with 41.6V cut-off voltage after the standard charge.
Discharge Performance	When connecting with load, the battery can supply power. Charge the battery with   standard  charge mode, then rest  for  0.2h, then discharge with 0.2C until the voltage is 41.6V.
Cycle Life	Test condition Charge: 0.2C to 58.4V Discharge: 0.2C to 41.6V 80% or more of 1st cycle capacity at 0.2C discharge of Operation
Self-discharge	After the standard charging, storied the Batteries under the       condition for 30days, then measured the capacity with 0.5C till 41.6V
Initial Impedance	Internal resistance measured at AC 1KHz after 50% charge
