RANGER 800 Battery Removal and Installation

Always wear safety glasses and nitrile gloves when servicing your Polaris RANGER 800, RANGER 800 XP, RANGER 800 HD or RANGER CREW 800. 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. 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 your Owner's Manual before installing the battery.

Full-Size RANGER 800

To remove the battery on your full-size RANGER 800, follow these steps: 

1. Park the vehicle on a flat, level surface. 

2. Place the vehicle in PARK and remove the key. 

3. Depending on which vehicle you have, remove the seat and storage bin or open the hood. Refer to your vehicle's Owner's Manual for battery locations. 

4. Remove the fasteners from the battery hold-down strap and remove the strap. On conventional batteries, remove the battery vent tube.

5. Disconnect the black (-) battery cable first.

6. Disconnect the red (+) battery cable last.

7. Lift the battery out of the vehicle. Be careful not to tip a conventional battery sideways, which could spill electrolyte. Warning: 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.

To install the battery on your full-size RANGER, follow these steps: 

1. Ensure that the battery is fully charged.

2. Place the fully charged battery in the battery holder.

  • On 2014 and newer RANGER 800 models, the battery terminals are positioned toward the rear, as seen below.
  • For 2014 and older RANGER 800 models, make sure the positive terminal is toward the driver's side of the terminal.

3. For conventional batteries only, install the battery vent tube and route it down in front of the shift cable and into the left front wheel well. Route the vent tube through the hole in the frame support from the back side and place it behind the wheel well panel. Coat the terminals with dielectric grease or petroleum jelly. Route vent tube as shown below to prevent electrolyte from damaging critical components (such as wire harness, brake lines, throttle cable).

2. Place the fully charged battery in the battery holder.

3. With 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. Connect and tighten the red (+) cable first. Connect and tighten the black (-) cable last. 

5. Coat the terminals with dielectric grease or petroleum jelly.

6. Verify that cables are properly routed. Cables should be safely tucked away at the front and rear of the battery.

7. Install the battery hold-down strap.

8. Turn the key ON to verify the battery has been connected properly. Tip: When the battery is disconnected, the vehicle’s clock may need to be reset.
