May 2018 Service ManualQuarterly Maintenance ProceduresPart No. 1275811GT GR ™ • QS™R • QS™ W 21Q-2Battery InspectionGenie specifications require that this procedure beperformed quarterly.Proper battery condition is essential to good engineand machine performance and operational safety.Improper fluid levels or damaged cables andconnections can result in engine and componentdamage and hazardous conditions.Electrocution/burn hazard.Contact with electrically chargedcircuits could result in death orserious injury. Remove all rings,watches and other jewelry.Bodily injury hazard. Batteriescontain acid. Avoid spilling orcontacting battery acid.Neutralize battery acid spills withbaking soda and water.Note: Fully charge the batteries and allow thebatteries to rest 24 hours before performing thisprocedure to allow the battery cells to equalize.1 GR-12, QS-12R, QS-12W: Raise the platformto approximately 3 ft / 1 m.GR-15, GR-20, QS-15R, QS-20R, QS-15W,QS-20W: Raise the platform to approximately3 ft / 1 m.2 Open the battery cover. Rest the cover againstthe chassis.3 Lower the platform until the mast just contactsthe battery cover.Crushing hazard. Keep handsclear of the battery cover whenlowering the platform.4 Be sure that the battery cable connections arefree of corrosion.Note: Adding terminal protectors and a corrosionpreventative sealant will help eliminate corrosionon the battery terminals and cables.5 Be sure that the battery retainers and cableconnections are tight.6 Be sure that the battery separator wireconnections are tight (if equipped).Models without maintenance-free or sealedbatteries:7 Put on protective clothing and eye wear.8 Remove the battery vent caps and check thespecific gravity of each battery cell with ahydrometer. Note the results.9 Check the ambient air temperature and adjustthe specific gravity reading for each cell asfollows:• Add 0.004 to the reading of each cell forevery 10° F / 5.5° C above 80° F / 26.7° C.• Subtract 0.004 from the reading of each cellfor every 10° F / 5.5° C below 80° F / 26.7°C.Result: All battery cells display an adjustedspecific gravity of 1.277 or higher. The batteryis fully charged. Proceed to step 11.Result: One or more battery cells display aspecific gravity of 1.276 or below. Proceed tostep 8.
