Standard Test Conditions:
Test should be conducted with new batteries within one week after
shipment from our factory
and the cells shall not be cycled more than five times before the
test.
Unless otherwise specified, test and measurement shall be done
under temperature of 20±5℃
and relative humidity of 45~85%.
If it is judged that the test results are not affected by such
conditions, the tests may be
conducted at temperature 15~30℃ and humidity 25~85%RH.
Appearance
There shall be no such defect as flaw, crack, rust, leakage, which
may adversely affect
commercial value of battery.
