IEC61951-2 ED3.0 Endurance in cycles
Before the endurance in cycles test, the cell shall be discharged at 0.2 1
t
A to a final voltage of 1.0V/sell.
The following endurance test shall then be carried out, irrespective of cell designation, in an ambient
temperature of 20℃±5℃.Charge and discharge shall be carried out at constant current throughout, using
the conditions specified in table 5.Precautions shall be taken to prevent the cell-case temperature from
risin
g above 35℃ during the test, by providing a forced air draught if necessary.
NOTE-Actual cell temperature, not the ambient temperature, determines cell performance.


It is permissible to allow sufficient open-circuit rest time after the completion of discharge at cycle 50,so
as to start cycle 51 at an exact two-week internal. A similar procedure may be adopted at cycles
100,150,200,250,300,350,400and 450.

If cell discharge voltage drops below 1.0V/cell,discharge may be discontinued.
Cycles 1 to 50 shall be repeated until the discharge duration on any 50
th
cycle becomes less than 3h at this
stage, a further cycle as specified for cycle 50 shall be carried out.
The endurance test is considered complete when two such successive cycles give a discharge duration less
than 3h.The number of cycles obtained when the test is completed shall be not less than 500.
