Battery

WARNING
Battery electrolyte is poisonous. It contains sulfuric acid. Serious burns can result from contact with skin, eyes or clothing.Antidote:External: Flush with water.Internal: Drink large quantities of water or milk. Follow with milk of magnesia, beaten egg, or vegetable oil. Call physician immediately.Eyes: Flush with water for 15 minutes and get prompt medical attention.Batteries produce explosive gases. Keep sparks, flame, cigarettes, etc. away. Ventilate when charging or using in an enclosed space. Always shield eyes when working near batteries. KEEP OUT OF REACH OF CHILDREN.
Your vehicle may have either a sealed battery, which requires little maintenance, or a conventional battery. A sealed battery can be identified by its flat covers on the top of the battery. A conventional battery has six filler caps on the top of the 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. Be careful not to allow cleaning solution or tap water into a conventional battery.

Battery Removal

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 black (negative) cable first. When reinstalling the battery, always connect the black (negative) cable last.
  1. Remove the driver’s seat. See Seat Removal.
  2. On conventional batteries, remove the battery vent tube.
  3. Disconnect the black (negative) battery cable first.
  4. Disconnect the red (positive) battery cable last.
  5. Lift the battery out of the vehicle. Be careful not to tip a conventional battery sideways, which could spill electrolyte.
NOTICE
If electrolyte spills, immediately wash it off with a solution of one tablespoon baking soda and one cup water to prevent damage to 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 on Battery Charging (Conventional Battery) before installing the battery.
An optional extreme use battery may be available for your model. If the performance of the factory-installed battery is inadequate due to operation in extreme cold or due to extended use of multiple electrical accessories, please see your POLARIS dealer or other qualified personnel. Ask your dealer to provide any installation procedures that may differ for an extreme use battery.
  1. Ensure that the battery is fully charged.
  2. Place the battery in the battery holder.
  3. On conventional batteries, install the battery vent tube (sealed batteries do not have a vent tube). The vent tube must be free of obstructions and securely installed. Route the tube away from the frame and vehicle body to prevent contact with electrolyte.
    WARNING
    Battery gases could accumulate in an improperly installed vent tube and cause an explosion, resulting in serious injury or death. Always ensure that the vent tube is free of obstructions and is securely installed as recommended.
  4. Coat the terminals with dielectric grease or petroleum jelly.
  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.
  8. Reinstall the driver’s seat.

Battery Storage

Whenever the vehicle is not used for a period of three months or more, recharge the battery about once a month to make up for normal self-discharge (see the Battery Charging section for details), or use a POLARIS Battery Tender, which can be left connected during the storage period. Battery Tender will automatically charge the battery if voltage drops below a pre-determined point. See the POLARIS products section for the part numbers.
During the storage period, park the vehicle out of the sun in a cool, dry place or remove the battery and store it in a cool, dry place.

Battery Fluid (Conventional Battery)

A poorly maintained battery will deteriorate rapidly. Check the battery fluid level often. Maintain the fluid level between the upper and lower level marks.
Image
Add only distilled water. Tap water contains minerals that are harmful to a battery.

Battery Charging (Conventional Battery)

  1. Remove the battery from the vehicle to prevent damage from leaking or spilled electrolyte during charging. See the Battery Removal section for details.
  2. Charge the battery with a charging output no larger than 1/10 of the battery’s amp/hr rating. Charge as needed to raise the specific gravity to 1.270 or greater.
  3. Reinstall the battery. See the Battery Installation section for details. Make sure the positive terminal is toward the driver’s side of the vehicle.

Battery Charging (Sealed Battery)

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. 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. Since the battery is sealed and the sealing strip cannot be removed, you must use a voltmeter or multimeter to measure DC voltage.
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.
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 battery voltage is 12.8 or greater.
TIP
When using an automatic charger, refer to the charger manufacturer's instructions for recharging. When using a constant current charger, use the guidelines on the next page for recharging.
Always verify battery condition before and 1-2 hours after the end of charging.
State of Charge Voltage Action Charge Time*
*(Using constant current charger @ standard amps specified on top of battery)
100% 12.8-13.0 volts None, check at 3 mos. from date of manufacture None required
75%-100% 12.5-12.8 volts May need slight charge, if no charge given, check in 3 months 3-6 hours
50%-75% 12.0-12.5 volts Needs charge 5-11 hours
25%-50% 11.5-12.0 volts Needs charge At least 13 hours, verify state of charge
