Starting use
5.2.1 The battery which has been stored for 3-6 months should be charged at 0.2C5A for 15 hours, then they can be put into operation.
5.2.2 The new battery which stored for more than 6 months should be charged at 0.2C5A for 12 hours, then discharged 5 hours. When the voltage is less than1.0V/cell within 5 hours, it can be stopped. Repeat the above charge and discharge for 3-5 cycles until the discharge duration is 5 hours and the battery voltage isn’t less than 1.0V/cell, charge it at 0.2C5A for 8h,and then the battery can be put into operation.
