— The test shall be performed at RT. — The discharges shall be performed at 2 C or at a different current if suggested and/or used by the supplier in testing before delivery. The charging shall be performed according to the recommendations of the supplier.— Five consecutive preconditioning cycles shall be performed. Fewer cycles may be agreed between the customer and supplier.— At the end of discharge, the battery pack or system voltage shall not go below the minimum voltage recommended by the supplier.— The battery pack or system shall be considered “preconditioned” if the discharged capacity during two consecutive discharges does not change by a value greater than 3 % of the rated capacity (30 min discharge or other discharge process adopted during test according to supplier indications). If the discharge process is equal to that used by the supplier on the same battery pack or system during factory tests, the data from the second cycle may be compared directly with the data from the supplier.— If the precondition requirements cannot be fulfilled, the customer and supplier shall agree on further procedure.NOTE The discharge rate of 2 C is used in order to shorten the preconditioning. 8 © ISO
