Checklist B Procedures

3 Be sure that the battery cable connections are
free of corrosion.
Note: Adding terminal protectors and a corrosion
preventative sealant will help eliminate corrosion
on the battery terminals and cables.
4 Be sure that the battery retainers and cable
connections are tight.
5 Be sure that the battery separator wire
connections are tight.
6 Fully charge the battery(s) and allow the
battery(s) to rest at least 6 hours.
7 Remove the battery vent caps and check the
specific gravity of each battery cell with a
hydrometer. Note the results.
8 Check the ambient air temperature and adjust
the specific gravity reading for each cell as
follows:
• Add 0.004 to the reading of each cell for
every 10° / 5.5° C above 80° F / 26.7° C.
• Subtract 0.004 from the reading of each cell
for every 10° / 5.5° C below 80° F / 26.7° C.
Result: All battery cells display an adjusted
specific gravity of 1.277 or higher. The battery
is fully charged. Proceed to step 12.
Result: One or more battery cells display a
specific gravity of 1.217 or below. Proceed to
step 9.
9 Perform an equalizing charge OR fully charge
the battery(s) and allow the battery(s) to rest
at least 6 hours.
