．Cycle Life
①Discharge to 1.3V at 300mA;
②Charge 120 minutes at 750mA constant
current with a voltage holding at 1.9V;
③Constant voltage holding at 1.9V to
charge 90 minutes until current drops to
50mA;
④Rest for 15 minutes;
⑤Discharge to 1.2V at a constant current
at 1500mA;
⑥Repeat steps from ② to ⑤ until the
capacity drops to 60%.

．Vibration
test
Store the cell more than 24 hours
after standard charge, following
vibration tests over an amplitude of 4
mm (0.1575 inches) at a frequency of
16.7 Hz(1000 cycles per minute) and
repeated through any axes during
60mins
