9.9.3 The battery shall then be tilted in each of the four directions at intervals of not less than 30 s between each tilting as follows: a) the battery shall be tilted through 45° from the vertical in a maximum period of 1 s; b) the battery shall be maintained in this position for 3 s; c) the battery shall be returned to the vertical position in a maximum period of 1 s. 9.9.4 Throughout the tests described in clause 9.9.3 , the battery must be examined for any sign of electrolyte leaking from the battery. The observations shall be recorded. 9.10 Cranking performance for dry-charged (or conserved-charge) batteries after activation 9.10.1 The dry-charged battery and a sufficient amount of electrolyte supplied by the manufacturer, or according to the manufacturer's specifications, shall be stored at 25 °C ± 2 °C for at least 12 h (before filling). 9.10.2 The battery shall be filled with its electrolyte up to the level indicated by the manufacturer. After a rest period of 20 min at the same ambient temperature, the battery shall be discharged at a current I= Icc. for 30s. The voltage after a discharge period of 30s (U30s) shall be recorded. The discharge shall then be terminated. Copyright
