24 Genie Lift Part No. 115417
Checklist B Procedures
B-1 Inspect the Battery - M odels wi th El ectric Winch B-1
Inspect the Battery -Models with
Electric Winch
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Proper battery condition is essential to good
machine performance and operational safety.
Improper fluid levels or damaged cables and
connections can result in component damage and
hazardous conditions.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid.
Neutralize battery acid spills with
baking soda and water.
1 Put on protective clothing and eye wear.
2 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.
3 Be sure that the battery retainers and cable
connections are tight.
4 Fully charge the battery. Allow the battery to
rest 24 hours before performing this procedure
to allow the battery cells to equalize.
5 Remove the battery vent caps and check the
specific gravity of each battery cell with a
hydrometer. Note the results.
6 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.
7 Perform an equalizing charge OR fully charge
the batteries and allow the battery to rest at
least 6 hours.
8 Remove the battery vent caps and check the
specific gravity of each battery cell with a
hydrometer. Note the results.
9 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 a specific
gravity of 1.277 or greater. The battery is fully
charged.Proceed to step 10.
Result: The difference in specific gravity
readings between cells is greater than 0.1 OR
the specific gravity of one or more cells is less
than 1.217. Replace the battery.
10 Check the battery acid level. If needed,
replenish with distilled water to 1/8 inch / 3 mm
below the bottom of the battery fill tube. Do not
overfill.
11 Install the vent caps and neutralize any
electrolyte that may have spilled.
