September 2015 Service ManualChecklist B ProceduresPart No. 218700 ZX-135/70 29B-1Inspect the BatteriesGenie specifications require that this procedure beperformed every 250 hours or quarterly, whichevercomes first.Proper battery condition is essential to good engineperformance and operational safety. Improper fluidlevels or damaged cables and connections canresult in engine component damage andhazardous conditions.There are 3 batteries on the machine. One is usedfor starting the engine and powering the controlsystem. The other two batteries are 6V DC deepcycle batteries which are wired in series to providepower for the auxiliary power units. The batteriesare charged by the alternator through a batteryseparator.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 Remove the cover from the auxiliary powerunit batteries located at the ground controlsside of the machine.Note: Perform the remaining steps on the auxiliarypower unit batteries and the engine starting battery.2 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.3 Be sure that the battery retainers and cableconnections are tight.4 Be sure that the battery separator wireconnections are tight (if equipped).Models without maintenance-free or sealedbatteries:5 Put on protective clothing and eye wear.6 Remove the battery vent caps and check thespecific gravity of each battery cell with ahydrometer. Note the results.7 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.
