BATTERY
Improperly connecting or disconnecting battery cables can result in an
explosion and cause serious injury or death. When removing the battery,
always disconnect the negative (black) cable first. When reinstalling the
battery, always connect the negative (black) cable last.
Your ATV is equipped with a sealed battery, which requires little maintenance.
POLARIS does not recommend using a conventional battery in this vehicle. The
orientation of the battery could result in electrolyte leakage, which would shorten
the life of the battery considerably.
Always keep battery terminals and connections free of corrosion. If cleaning is
necessary, remove corrosion with a stiff wire brush. Wash with a solution of one
tablespoon baking soda and one cup water. Rinse well with tap water and dry off
with clean shop towels. Coat the terminals with dielectric grease or petroleum
jelly.
