Battery and Electrical Systems Battery Conductance Analyzer
Conductance describes the ability of battery to conduct currentA conductance tester functions by sending low frequency AC signal through the battery and portion of the current response is captured, from this output conductance measurement is calculatedConductance testing is more accurate than voltage, specific gravity, or load testingAuthorized Polaris dealersdistributors are required to use the conductance analyzer when testing 12V Polaris batteries
Battery Off Season Storage
Whenever the vehicle is not used for period of three months or more, remove the battery from the vehicle, ensure that it's fully charged, and store it out of the sun in cool, dry placeCheck battery voltage each month during storage and recharge as needed to maintain full chargeNOTE: Battery charge can be maintained by using Polaris battery tender charger or by charging once month to make up for normal self-dischargeBattery tenders can be left connected during the storage period, and will automatically charge the battery if the voltage drops below pre-determined point
