9.6.5.8 The cycling test should be considered complete when the terminal voltage at 30 s (U30s) of 9.6.5.6 falls to below 7,20 V.The number of cycles shall be determined by plotting the 30s (U30s) voltage values versus the cycle values. The point where the line crosses 7,20 V shall be the cycle reported for that battery. 9.6.5.9 Requirements: number of cycles, see Clause 10. 9.6.6 Endurance test sequence According to their classification, batteries are submitted to the test sequence defined in Tables 4 and 5.
