15. Recharge the battery using either 15.1, or 15.2 or 15.3
• Adjust the electrolyte level at a current of 0.2*I
minutes prior to end of the charge methods, 15.1, 15.2, and 15.3.
• 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 cells end of charge voltages in the logbook.
ATTENTION:
• Do not charge the battery with currents higher than I
• If you cannot fully supervise, do not use method described in
15.3.
15.1 IUI-charge = IUI charge – method Appendix 1)
• Charge the battery at I
times 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
15.2 I charge method (Appendix 2)
• Charge the fully discharged battery for seven hours at 0.2*I
15.3 II charge method (Appendix 3)
• 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
time presented in the table below.

16. Allow the battery to stand for one hour to support the escapes
of charging gases from cells.
17. Tighten the vents between 1 and 24 hours after charging and fit
the lid onto the case.
18. Release the battery to service, if required in accordance with Task 3.3.
