MAINTENANCE

Battery

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 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 page 122 
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.
