14. Recharge the battery using a method indicated in section 14.1 or 14.2
or 14.3
• Adjust the electrolyte level at a current of 0.2*I
minutes prior to end of the charge methods, 14.1, 14.2, and 14.3
• Afterwards measure the voltage on each cell prior to the end of
charge at 0.2*I .
1
Requirement: cell voltage shall be ≥ 1.56 V
• Record the values in the log book.
Note:
If the battery has to be charged below 0°C, apply 7 hours charge
at 0.2*I .

ATTENTION:
• Do not charge the battery with currents higher than I
• If you cannot fully supervise, do not use method described
in 14.3.
14.1 IUI charge – method (Appendix 1)
• Charge the battery at I until voltage has increased to 1.55V times
1
number of cells and charge for 2 hours at 0.2*I
• After about 1 hour charge, check that battery has reached the
voltage level to switch the charge current to 0.2*I
14.2 I charge method (Appendix 2)
• Charge the fully discharged battery for seven hours at 0.2*I
14.3 II charge method (Appendix 3)
ATTENTION:
• Charge the fully discharged battery with parameters selected
from the table below and afterwards charge for two hours at
0.2*I

• Check battery current switching to 0.2*I
presented in the table below.

15. Stand the battery for 1 hour minimum and 24 hour maximum and
then refit the vents on the cells and fit the lid in its correct
orientation as indicated by the arrowhead which points in the
direction of the main connector.
