positive-ignition engines shall be preconditioned with one Part One and two Part Two driving cycles according to paragraph 3.1.2.5.3. below.
              3.1.2.3. After this preconditioning, and before testing, the vehicle shall be kept in a room in which the temperature remains relatively constant between 293 and 303 K (20 °C and 30 °C). This conditioning shall be carried out for at least six hours and continue until the engine oil temperature and coolant, if any, are within ±2 K of the temperature of the room, and the electrical energy/power storage device is fully charged as a result of the charging prescribed in paragraph 3.1.2.4. below.
3.1.2.4. During soak, the electrical energy/power storage device shall be charged:
  (a) With the on board charger if fitted; or
  (b) With an external charger recommended by the manufacturer, using    the normal overnight charging procedure.
               This procedure excludes all types of special charges that could be automatically or manually initiated like, for instance, the equalization charges or the servicing charges.
               The manufacturer shall declare that during the test, a special charge procedure has not occurred.
              3.1.2.5. Test procedure
              3.1.2.5.1. The vehicle shall be started up by the means provided for normal use to the driver. The first cycle starts on the initiation of the vehicle start-up procedure.
              3.1.2.5.2. The test procedures defined in either paragraph 3.1.2.5.2.1. or 3.1.2.5.2.2. may be used in line with the procedure chosen in Regulation No. 101, Annex 8, paragraph 3.2.3.2.
              3.1.2.5.2.1. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and end on conclusion of the final idling period in the extra-urban cycle (Part Two, end of sampling (ES)).
              3.1.2.5.2.2. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and continue over a number of repeat test cycles. It shall end on conclusion of the final idling period in the first extra-urban (Part Two) cycle during which the battery reached the minimum state of charge according to the criterion defined below (end of sampling (ES)).
               The electricity balance Q [Ah] is measured over each combined cycle, using the procedure specified in Appendix 2 of Annex 8 to Regulation No. 101, and used to determine when the battery minimum state of charge has been reached.
               The battery minimum state of charge is considered to have been reached in combined cycle N if the electricity balance measured during combined cycle N+1 is not more than a 3 per cent discharge, expressed as a percentage of the nominal capacity of the battery (in Ah) in its maximum state of charge, as declared by the manufacturer. At the manufacturer's request additional test cycles may be run and their results included in the calculations
