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 129
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, your POLARIS dealer can assist. Your dealer can 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. 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. Cables should be safely
tucked away at the front and rear of the battery.
8. Close and secure the front box and cover.

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.
POLARIS recommends maintaining battery charge by using a
POLARIS Battery Tender charger or by charging about once a month to
make up for normal self-discharge. Battery Tender can be left connected
during the storage period, and will automatically charge the battery if
the voltage drops below a pre-determined point. See page 143 for the
part numbers of POLARIS products.
