Checklist B Procedures; Inspect The Batteries - Genie S-80 Service Manual

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.
A single battery configuration is standard. A dual
battery option is available, where one battery is
used to start the engine and the other is used to
power the control system and auxiliary power unit.
The two batteries are charged by the alternator
through a battery separator.
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.
Note: Fully charge the batteries and allow the
batteries to rest 24 hours before performing this
procedure to allow the battery cells to equalize.

Checklist B Procedures

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 Be sure that the battery separator wire
connections are tight (if equipped).
Models without maintenance-free or sealed
batteries:
5 Put on protective clothing and eye wear.
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° F / 5.5° C above 80° F / 26.7° C.
• Subtract 0.004 from the reading of each cell
for every 10° F / 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 1.276 or below. Proceed to
step 8.
8 Perform an equalizing charge OR fully charge
the battery(s) and allow the battery(s) to rest at
least 6 hours.
