Standard discharge means discharging at 2.5A down to 2.6V, in 25℃.
Contact discharge ± 8KV , Air discharge ± 12KV
Apply 6V/2.5A current with reverse polarity for 2.5 hour at fully charged state.
No explode, No fire
After Fully charged, continuously charge by constant current 2.5A and constant voltage of 6V for
No explode, No fire
After fully charged connect positive andnegative terminal with a copperwire ofresistance less than 100m
Ohm.
No explode, No fire
After standard charge, within 1 hour, the duration time of standard discharge is measured and the
capacity more than 13000 mAh.
Packs shall be charged and discharged per 4.1.6, 300cycles at 25℃±2℃. 301st discharge capacity
shall be measured capacity≧9750 mAh.
Charge pack with 2.5A CC charge to 4.2V,then CV charge till charge current dealine to 268mA,
rest for 10min, and discharge pack with 2.5A dischargeing current until pack voltage reaches
2.6V, rest for 10 minutes between each charge/discharge step, in 25℃.
Standard charge means 2.5A CC charge to 4.2V,then CV charge till charge current dealine to 268mA,
in 25℃.
