CAUTION
Do not install partially charged battery on snowmobile since the casing might crack at freezing temperatureThe following chart shows the freezing point of the electrolyte in relation to the charge of the batteryTemperaturecorrected Specific Gravity 1.260 1.230 1.200 1.170 1.110 Battery Charge Fully Charged 34 Charged 12 Charged 14 Charged Discharged Freezing Point of Electrolyte -59C -40C -27C -18C -7C (-74F) (-40F) (-16F) (0F) (+19F)
Clean battery terminals and cable connections using wire brushApply light coat of dielectric grease (PN 413 7017 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 battery with clear water and dry well using clean clothStore battery 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)
