Inspect the Batteries

Genie specifications require that
this procedure be performed every
250 hours or quarterly, whichever
comes first.
Proper battery condition is essential to good engine
performance and operational safety. Improper fluid
levels or damaged cables and connections can
result in engine component damage and hazardous
conditions. There are 2 batteries on the machine.
One starts the engine and the other powers the
control system. The batteries are charged by the
alternator through a battery separator.
Electrocution hazard. Contact with
hot or live 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.
Adding terminal protectors and a
corrosion preventative sealant will
help eliminate corrosion on the
battery terminals and cables.
3 Be sure that the battery hold downs and cable
connections are tight.
4 - 18
4 Be sure that the battery separator wire
connections are tight.
5 Fully charge the batteries and allow the batteries
to rest at least 6 hours.
6 Remove the battery vent caps and check the
specific gravity of each battery cell with a
hydrometer. Note the results.
7 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 11.
Result: One or more battery cells display a
specific gravity of 1.217 or below. Proceed to
step 8.
8 Perform an equalizing charge, OR fully charge
the batteries and allow the batteries to rest at
least 6 hours.
