7.3.5.1 With Constant voltage
If the charger´s maximum voltage setting is too low to supply constant current charging divide the battery
into two parts to be charged individually.
When the battery has been:
Delivered unfi lled and discharged: After a period of 5 hours from fi lling the electrolyte in the battery
should be charged for 30 hours at the rated charging voltage of 1.65 V/cell. The current limit should be
0.2 ItA maximum. Approximately 4 hours after the end of charging the electrolyte level should be adjusted
to the upper electrolyte level marking “MAX” by using only genuine electrolyte. For cells with steel cases
the electrolyte level should be adjusted to the maximum level according to the “Instruction for the control
of electrolyte level”. During the charge the electrolyte level and temperature should be observed see point
5.4. The electrolyte level should never fall below the “MIN” mark.
Delivered fi lled and discharged: The battery should be charged for 30 hours at the rated charging
voltage of 1.65 V/cell. The current limit should be 0.2 ItA maximum. Approximately 4 hours after the end
of charging the electrolyte level should be adjusted to the upper electrolyte level marking “MAX” by using
distilled or deionized water in accordance with IEC 60993. For cells with steel cases the electrolyte level
should be adjusted to the maximum level according to the “Instruction for the control of electrolyte level”.
During the charge the electrolyte level and temperature should be observed see point 5.4. The electrolyte
level should never fall below the “MIN” mark.
Delivered fi lled and charged and stored for more than 12 months: the battery should be charged
for 30 hours at the rated charging voltage of 1.65 V/cell. The current limit should be 0.2 ItA maximum.
Approximately 4 hours after the end of charging the electrolyte level should be adjusted to the upper
electrolyte level marking “MAX” by using distilled or deionized water in accordance with IEC 60993. For
cells with steel cases the electrolyte level should be adjusted to the maximum level according to the
“Instruction for the control of electrolyte level”. During the charge the electrolyte level and temperature
should be observed see point 5.4. The electrolyte level should never fall below the “MIN” mark.
Delivered fi lled and charged: A 10 hour charge at the rated charging voltage of 1.65 V/cell must
be carried out before putting the battery into operation. The current limit should be 0.2 ItA maximum.
Approximately 4 hours after the end of charging the electrolyte level should be adjusted to the upper
electrolyte level marking “MAX” by using distilled or deionized water in accordance with IEC 60993. For
cells with steel cases the electrolyte level should be adjusted to the maximum level according to the
“Instruction for the control of electrolyte level”. During the charge the electrolyte level and temperature
should be observed see point 5.4. The electrolyte level should never fall below the “MIN” mark.
