Put the battery into an oven of constant humidity
(90%~95%)
and constant temperature (40±2
℃
), rest for 48 hours,
take it out and rest for 2 hours at 23±2
℃
, then
discharge with 1.0CmA ,12.0V cutting off.
Fix the battery on a vibration table, vibrate it at X, Y, Z
orientation. Change the frequency of vibration with
1Hz/min from 10Hz to 55Hz, redo it for 30min
Frequency: 10~30Hz Swing distance: 0.38mm
Frequency: 30~55Hz Swing distance: 0.19mm
Do the free drop test according to the condition
described below after finished the vibration test
Altitude: 1.0m
Receiver: a hard board of 18~20mm
Orientation: Six sides of battery at horizontal
Discharge the battery to 12.0V with 1.0CmA CC, then
charge-discharge the battery 3 cycles, measure the
discharge capacity
