Se ion ELECT RI CAL Sub-Section 04 (BATTERY)
The battery must always be stored in fully charged conditionIf required, charge until specific gravity of 1.260 is obtained, CAUTIONBattery electrolyte temperature must not exceed 50C (122F)The casing should not feel hotClean batte terminals and cable connections using wire brushApply light coat of dielectric grease (P 4137017 00) or petroleum jelly on terminalsClean battery casing and caps using solution of baking soda and waterDo not allow cleaning solution to enter battery, otherwise it will destroy the electrolyteRinse battety with clear water and dry well using clean clothStore battety on wooden shelf in cool dry placeSuch conditions reduce self-discharging and keep fluid evaporation to minimumDuring the storage period, recheck electrolyte level and specific gravity readings at least every 40 daysAs necessary, keep the battery at its upper level line and near full charge as possible (trickle charge)A017 004015.1
2Remove caps and fill battery to UPPER LEVEL line with electrolyte (specific gravity1.260 at 20C (68F))3Allow the battery to stand for 30 minutes MINlMUM so that electrolyte soak through battery cells
