The battery is fullycharged. Proceed to step 10.Result: One or more battery cells display aspecific gravity from 1.269 to 1.218. The batteryis still usable, but at a lower performance so willneed to be recharged more often. Proceed tostep 11.Result: One or more battery cells display aspecific gravity from 1.217 to 1.173. The batteryis approaching the end of its life. Proceed tostep 11.Result: The difference in specific gravityreadings between cells is greater than 0.1 ORthe specific gravity of one or more cells is 1.172or less. Replace the battery.10 Check the battery acid level. If needed,replenish with distilled water to 1/ 8 inch / 3 mmbelow the bottom of the battery fill tube. Do notoverfill.11 Install the vent caps and neutralize anyelectrolyte that may have spilled.B-2Inspect the Electrical WiringNote: Genie specifications require that thisprocedure be performed every 250 hours orquarterly, whichever comes first.Maintaining electrical wiring in good condition isessential to safe operation and good machineperformance.
