5.6 Endurance test
Replace the title by “5.6  Endurance tests for vented batteries”.
5.6.3 Replace the entire subclause by the following:
5.6.3 Requirement 2
5.6.3.1 Charging conditions
Charging voltage depends on the battery technology and is, therefore, related to the battery water loss
level (see Table 3). The water loss level used should be the value that is declared by the manufacturer. If
this is not available, then it should be determined by tests according to 5.7.
Table 3
Water loss Voltage
Very low  (VL) 16 V ± 0,10 V
Low    (L) 15,2 V ± 0,10 V
Normal  (N) 14,8 V ± 0,10 V
The battery shall be charged at one of these voltages with the maximum current in amperes
being limited to I = 5 I (see 3.1.2). The charging time, which can change according to the test
max n
procedure, is defined in 4.2. The battery temperature shall be maintained in the range 25 °C to
35 °C. If necessary, an appropriate environmental control system shall be used, e.g. a water
bath.
5.6.3.2 Corrosion test
5.6.3.2.1 The test shall be carried out on batteries which have been charged in accordance with
5.6.3.1 for 16 h.
5.6.3.2.2 The battery shall be placed in a water-bath maintained at a temperature of 60 °C ± 2 °C. The
