Battery

WARNING
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 vehicle has a low-maintenance battery. Always keep battery terminals and connections free of corrosion. If cleaning is necessary, remove the 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.

Battery Removal

  1. Access the battery via the front underhood storage.
  2. Disconnect the black (negative) battery cable first.
  3. Disconnect the red (positive) battery cable last.
  4. Remove the battery hold-down strap.
  5. Lift the battery out of the vehicle.

Battery Installation

Using a new battery that has not been fully charged can damage the battery and result in a shorter life. It can also hinder vehicle performance. Follow the battery charging instructions in the AGM Battery Maintenance and Charging section before installing the battery.
  1. Ensure that the battery is fully charged.
  2. Place the battery in the battery holder.
  3. Coat the terminals with dielectric grease or petroleum jelly.
  4. Secure the battery hold-down strap.
  5. Connect and tighten the red (positive) cable first.
  6. Connect and tighten the black (negative) cable last.
  7. Verify that cables are properly routed.

Battery Maintenance and Charging

WARNING
An overheated battery may explode, causing severe injury or death. Always watch charging times carefully. Stop charging if the battery becomes very warm to the touch. Allow it to cool before resuming charging.
The sealed battery is already filled with electrolyte and has been sealed and fully charged at the factory. Never pry the sealing strip off or add any other fluid to this battery.
The single most important thing about maintaining a sealed battery is to keep it fully charged. Check the battery voltage with a voltmeter or multimeter. A fully charged battery will register 12.8 V or higher. If the voltage falls below 12.5V, charge it immediately, or the battery runs the risk of sulfation and reduced battery life.
If you do not drive the vehicle for more than TWO WEEKS, Polaris recommends using a BatteryMINDer® 2012 AGM - 2 AMP charger (PN 2830438), which can be ordered through your dealer.
Polaris provides a charging accessory with your vehicle that allows easy connection to the battery through the 12V auxiliary outlet, located on the dash. During charging, place the charger outside of the vehicle and protect it from moisture.

If you plan to store the vehicle for ONE MONTH or longer, remove the battery from the vehicle, then store the battery in a cool and dry location. Continue to maintain the battery with the BatteryMINDer® 2012 AGM - 2 AMP charger.
When using an automatic charger other than a BatteryMINDer® 2012-AGM - 2 AMP charger, refer to the charger manufacturer's instructions for recharging.
If using a constant current charger (instead of BatteryMINDer® 2012 AGM - 2 AMP charger), use the guidelines below. Always verify battery condition before and 1-2 hours after the end of charging.
State of Charge Voltage (DC) Action Charge Time*
100% 12.8-13.0 volts None, check monthly None required
75%-100% 12.6-12.8 volts May need slight charge, if no charge given, check in 2 weeks 3-6 hours
50%-75% 12.3-12.6 volts Needs charge 5-11 hours
25%-50% 12.0-12.3 volts Needs charge At least 13 hours
0%-25% 12.0 volts or less Needs charge At least 20 hours

* Using AGM specific charger at standard amps specified on top of battery
