Lead acid starter batteries – General requirements and methods of tests for motorcycle batteries
| Published By | Publication Date | Number of Pages |
| BSI | 2015 | 16 |
This European Standard is applicable to lead-acid batteries used primarily as a power source for the starting of internal combustion engines, lighting and ignition of motorcycles, power sport vehicles and all-terrain vehicles up to a maximum capacity of 35 Ah (C 10) (further on referred as batteries). The nominal voltage is 12 V or 6 V.
Test definitions and criteria in this document are written for batteries with a nominal voltage of 12 V only. For batteries with a nominal voltage of 6 V all voltages have to be divided by two.

The duration t [h] of this discharge shall be recorded. The be… 7.2.3 The capacity Ce [Ah] is 7.2.4 Requirements 7.3 Cranking performance test 7.3.1 After a rest period of up to 72 h after preparation according to 7.1, the battery shall be placed in a cooling chamber with (forced) air circulation at a temperature of −18 C ± 1 C until the temperature of the middle cells has reached −18 C ±… 7.3.2 The battery shall then be discharged, either inside or outside the cooling chamber, within 2 minutes of the end of the cooling period, with a current Icc (see 5.1.2). This current shall be kept constant to within ± 0,5% during the discharge. 7.3.3 After 10 s discharge, the terminal voltage Uf shall be recorded in Volts and the current shall be cut off. 7.3.4 The test shall be continued after a rest time of 10 s ± 1 s. 7.3.5 The battery shall then be discharged at 0.6 Icc. The current shall be kept constant to within ± 0,5 % during the discharge. The discharge shall be terminated when the battery voltage reaches 6,0 V. The discharge time t’6v shall be recorded in se… |
| 11 | 7.3.6 t6v is defined as the duration of the second stage (t’6v) plus the equivalent duration of the first stage discharge if run at 0,6 Icc, i.e. it is given, in seconds, by the following formula: 7.3.7 Requirements 7.4 Endurance test 7.4.1 General 7.4.2 Discharge the battery for 2 h with a constant current of I = 2,5 I10. Cut off criterion for this test is the voltage during the discharge. If it drops below 10,5 V the test shall be terminated. 7.4.3 Recharge the battery for maximum 5 h with a constant voltage of 15,6 V for flooded batteries and 14.4 V for valve regulated batteries (if not specified differently by the battery manufacturer) and a maximum current of Imax = 2,5 I10. Record the … 7.4.4 If the ratio CR < 1,08 (or any lower value specified by the manufacturer) in step 7.4.3 recharge the battery with a constant current of I = 0,5 I10 until the ratio CR reaches 1,08 (or any lower value specified by the manufacturer) or until the m… 7.4.5 Perform steps 7.4.2 to 7.4.4 as long as the voltage during discharge is above the limit. 7.4.6 Requirements 7.5 Charge retention test 7.5.1 The tests shall be carried out on fully charged batteries in accordance with 7.1. Cell plugs shall be closed but any venting system shall be open. 7.5.2 The battery shall be placed in a climate chamber at 40 C ± 2 C for 21 days on open circuit. No connecting clamps or cables shall be connected to the terminals. 7.5.3 After the storage time the battery shall be placed in a cooling chamber with (forced) air circulation at a temperature of −18 C ± 1 C until the temperature of the middle cells has reached −18 C ± 1 C. |
