Battery Installation (850 Models)

When installing a new battery, make sure it's fully charged prior to its initial use. 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 before installing the battery.
  1. Ensure that the battery is fully charged.
  2. Set the battery in the battery holder.
  3. Place the battery shield on the battery bracket.
  4. Install the battery hold-down strap.
  5. Connect and tighten the red (positive) cable first.
  6. Connect and tighten the black (negative) cable last.
    caution
    Verify the battery cables and wiring harness do not come into contact with the brake disc. Move the wiring harness/cables behind the chassis tube and away from the brake disc.
  7. Route the BROWN harness ground wires and BLACK main battery ground cable as shown in the image. Both are routed up and over the rubber strap. If the ground wires/cable are routed down the side of the battery, they may interfere with the rear side panel tab. Note the routing of the RED (positive) battery cable and that the right fender is pulled away from the chassis. Item is the constant power fuse connector.

  8. Verify that cables are properly routed.
    NOTICE
    Ensure that the battery wires are routed in such a way that they cannot come into contact with the brake disc.
  9. Secure the right fender using the plastic rivet.
  10. Reinstall the console using the two plastic rivets. Reinstall the side panel.

Battery Storage

Whenever the vehicle is not used for a 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 a cool, dry place. Check battery voltage each month during storage and recharge as needed to maintain a full charge.
TIP
Battery charge can be maintained by using a POLARIS Battery TenderTM charger or by charging about once a month to make up for normal self-discharge. Battery TenderTM can be left connected during the storage period, and will automatically charge the battery if the voltage drops below a pre-determined point.

Battery Charging

The following battery charging instructions apply only to the installation of a sealed battery. Read all instructions before proceeding with the installation of this battery.
The sealed battery is already filled with electrolyte and has been sealed and fully charged at the factory. Do not ever 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. Since the battery is sealed and the sealing strip cannot be removed, you must use a voltmeter or multimeter to measure DC voltage.
For a refresh charge, follow all instructions carefully.
  1. Check the battery voltage with a voltmeter or multimeter. A fully charged battery will register 12.8 V or higher.
  2. If the voltage is less than 12.8 volts, recharge the battery at 1.2 amps or less until the battery voltage is 12.8 or greater.
RESTRICTION
When using an automatic charger, refer to the charger manufacturer's instructions for recharging. When using a constant current charger, use the following guidelines for recharging.
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.
TIP
Always verify battery condition before and 1-2 hours after the end of charging.
