Accordance of shortest discharging time

1. Testing 9 batteries of each discharging way

2. The result of the average discharging time from each discharging standard shall be equal to or more than the average minimum time requirement; no more than one battery has a service output less than 80% of the specified requirement

3. The result of the average discharging time from each discharging standard shall be equal to or more than the average minimum time requirement, if one battery has a service output less than 80% of the specified requirement then take another 9 pieces to test again. This lot of batteries are qualified if the result meets the NO.2 provision. If not qualified then will not test again.
