    • Discharge and Charge Conditions (80%DOD, 20 to 25℃)

(1) Cycle method: Discharge with 2I10 for 4 hours (80% DOD), charge with 2I10 for 3.5hour + I10 for 1hour + 0.25I10 for 3.5hour. This is one cycle.


(2) Residue Capacity determination: The batteries are discharged at 10 hour rate after every 50 cycles to test battery capacity. When residue capacity of 10 hour rate capacity is lower than 80%, test is ended. After discharge at 10 hour rate after every 50cycles, the charge method is: charge 80% of discharged capacity with current of 2I10 + charge 20% with current of I10 + charge 20% with current of 0.4I10 (i.e. charge 120% of discharged capacity)
