Discharge characteristics

 

0.3C5A 100

1.5C5A 90

a) After standard charged, rest for 30min and then discharge at0.2C5Aand1C5Ato the discharge cut-off voltage respectively. Charge/discharge cycle can be conducted for 5 times before meeting the Standardsthe same below.

b) Discharging current and discharging time can be calculated by AH, and expressed by the percentage of nominal capacity. (Cycled by 3 times, when one of the three reaches the standard, it will meet the standard.)

Charge retention under normal condition

 

Residual capacity

nominal capacity *80

Recovery capacity

nominal capacity *90

Stored for 28 days after standard charge, discharge at0.3 C5Ato the discharge cut-off voltage, then test the residual capacity. Teat the recovery capacity, if one of the three cycles can reach the standard, it represents the battery has reached the standard.
