27. Allow the battery to soak to room temperature, which can take up
to 8 hours
28. Recharge the battery using either 28.1, or 28.2 or 28.3
• Adjust the electrolyte level at a current of 0.2*I
1
15 minutes to 10
minutes prior to end of the charge methods, 28.1, 28.2, and 28.3
• 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:
• Don’t charge the battery with currents higher than I
1
•I
f you can’t fully supervise, don’t use method described in 28.3.
28.1 IUI charge – method (Appendix 1).
• Charge the battery at I
1
until voltage has increased to 1.55V times
number of cells and charge for 2 hours at 0.2*I
1
• After about 1 hour charge, check that battery has reached the
voltage level to switch the charge current to 0.2*I
1
.
28.2 I charge method (Appendix 2).
• Charge the fully discharged battery for seven hours at 0.2*I
1
.
28.3 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
1
• Check battery current switching to 0.2*I
1
at the stage 1(max) time
presented in the table below.
29. Measure the electrolyte density on cells in accordance with
Task 8.4.
30. Refit the vents on the cells between 1 hour and not later than 24
hours after charge.
31. Refit the lid on the battery case.
32. Measure the insulation resistance in accordance with Task 8.3
Requirement: Insulation resistance ≥10 MΩ.
If less than 10 MΩ, remove the lid and allow the battery to stand
for 24 hours in a dry ventilated environment.
33. Release the battery to service, or if required in accordance with
Task 3.3.
