THEN attach a copy of the Condition Report to this procedure. - IF NOT, THEN mark this step N/A. -

Verify that the requirements of Housekeeping Level I1 have been met.

Verify that the battery log book has been updated to include the following:

9.3.1 Date this procedure was performed.

9.3.2 Time this procedure was completed.

9.3.3 Performer of this procedure.

9.3.4 Any problems encountered and corrective action taken.

NOTE - 124.7 VDC is the Tech. Spec. Value (lower limit) for a 58-cell bank's float voltage. However, the as left float voltage should be 127.6 to 130.5 when measured at the battery terminal.

9.4 Verify that the battery bank float voltage measured in step 8.1.1 is equal to or greater than 124.7 M C when on normal float charse. -

9.5 Verify that the average cell temperature calculated in Section 8.2.5 is greater than 60°F.

9.6 Verify that the Electrolyte levels in Section 8.1.4 are above the minimum line and equal to or less than 1/4" above the maximum line.

9.7 Verify that the average corrected specific gravity of the battery is qreater than 1.200. -

9.8 Verify that the corrected specific gravlty of each cell is not below the allowable value calculated in step 8.2.10.B.

9.9 Verify that the "As Left" corrected single cell voltage euual to or qreater than 2.13 VDC when on normal float - charge.
