BS EN 50342-7:2015 pdf download – Lead acid starter batteries Part 7: General requirements and methods of tests for motorcycle batteries The cranking current is the discharge current l.. measured in A to be indicated by the manufacturer which abattery can supply at -18 °C according to 7.3. 5.1.3Charge retention The charge retention is the ability of a battery to maintain the cold cranking performance after open circuitstorage for a certain time under increased temperature conditions (see 7.5). 5.1.4 Endurance The endurance reflects the ability of a battery to perform repeated dischargelrecharge cycles under specifictest conditions (see 7.4). 5.1.5 Water consumption The water consumption is the loss in weight of a battery measured in g / (Ah C1o.) during overchargeconditions (see 7.6). 5.1.6Water basin lf a test needs to be carried out in a water basin, the following conditions shall be fulfilled.The terminal base ofthe battery shall be at least 15 mm, but not more than 25 mm, above the level of the water. If several batteriesare in the same water bath, the distance between them and the distance to the walls of the bath shall be atleast 25 mm. 5.2Sampling of batteries All tests shall be carried out on new battery samples. Samples shall be considered as new no longer than . 30 days after the acid filling and formation date in the case of filled and charged batteries, . 60 days after shipment date of the manufacturer in the case of dry-charged batteries. Out of different production or sampling lots, five batteries shall be selected for testing.Four of these batteriesshall be used for the tests. In case of equipment failures or technical deviations, one battery can be replacedto repeat the complete sequence for this battery. 5.3Measuring instruments Refer to EN 50342-1. 6 Test sequence The test sequence for the four required samples is shown in Table 1. First the batteries have to pass the test steps 1 to 7.The requirements of Cto capacity check and crankingperformance test have to be fulfilled at least once for each sample. lf the requirements are fulfilled in the firstor second capacity check / cranking performance test the following capacity checks / cold cranking tests don’thave to be completed. Only if the Cto capacity check and the cold cranking test are successful, the test sequence shall be continuedwith steps 8 to 11.These tests shall commence no later than one week after competition of...
