Batteries

This vehicle is equipped with eight 12-volt batteries that supply the power needed to operate the vehicle. The batteries are located under the seat.

Always observe all battery safety warnings and safe handling procedures as outlined on vehicle safety labels and in this manual.

Battery Handling Precautions

Always make sure that all electrical accessories are grounded directly to the negative (-) post on the terminal board. Never use the chassis or body as a ground connection.
Always keep battery terminals and connections clean and free of corrosion at all times.
Always maintain a full charge on the batteries. For best battery life, avoid discharging the batteries more than 80%.
Make sure new batteries are fully charged before using.
New deep cycle batteries need to be cycled several times before reaching full capacity (50- 125 cycles, depending on type). Capacity will be limited during this time.
Make sure vent caps are installed properly and securely during vehicle operation and battery charging.
Recharge batteries fully at the end of each day the vehicle is operated, allowing adequate time for the charger to complete its charge cycle. The batteries in this vehicle do not have a “memory effect”. Frequent charging will extend their life.
Avoid charging at temperatures above 120° F. (49° C.) ambient air temperature. Closed, unvented storage buildings often exceed this temperature when exposed to direct sunlight.
Never connect an auxiliary battery to the factory-installed DC-to-DC converter. If more than 10 amps are needed for accessories, always install the POLARIS-approved auxiliary accessory battery kit.
Never connect a 12-volt accessory directly to the batteries. Always connect any powered accessory to a 12-volt auxiliary outlet or terminal board.
Never connect jumper cables to any of the batteries of this vehicle.
Use only insulated tools when working in the battery compartment.

Battery Conditioning

New batteries cannot initially hold all of their capacity. The approximate capacity of the battery pack increases as the number of charge cycles increases.

Number of Charge Cycles:	New	15	30	45
Percentage of Full Capacity	80%	90%	95%	100%

Ambient Temperature Implications on Batteries

Battery range decreases as ambient temperature decreases. This can affect the range by up to 30%.
Batteries discharge when left uncharged. They can discharge up to 13% per month (higher rates in warmer climates) with the key off and much faster if the key is left on.
Batteries can freeze if left uncharged at low ambient temperatures.

Percent Charged	100%	50%	0%
Approx. Freezing Point	-60° F (-51° C)	0° F (-18° C)	25° F (-4° C)

Charger Operation

Open the hood and any door enclosures or zippers. This will decrease charger temperature, which allows it to operate more efficiently, and shorten charge times. See Battery Charging for charging procedures.

Always use extension cords with the appropriate ratings for the country in which it is used. In North America this is a UL rating. The cords must also be rated for the conditions in which they are used, such as being rated for protection from oil in a garage or workshop environment.
Use the proper cord wire gauges for the cord length used.

Length:	<25 ft (7.5 m)	<50 ft (15 m)	<100 ft (30 m)
Gauge:	16AWG (1.5mm2)	14AWG (2.5mm2)	10AWG (6.0mm2)

Battery Operation Range

Range is significantly affected by tire pressure, alignment, terrain and driving style. Always maintain proper tire pressure as specified on safety labels.

Main Power Connector

WARNING

Insulate any tools used within the battery area to prevent sparks or battery explosion caused by shorting the battery terminals or wiring. Remove the batteries, or cover the exposed terminals with an insulating material.

NOTE

Damage to electrical connections and components will occur if they are unplugged before the main power connector is disconnected. Always disconnect the main power connector before servicing or unplugging any electrical components.

When disconnected, the main power connector

disconnects the battery pack from all electrical components, with the exception of the contactor. After servicing the vehicle, the main power connector should be the last connection to be made.

The main power connector is located under the seat on the driver’s side of the controller tray, adjacent to the main line contactor. To disconnect, unplug the connector.
To disconnect the battery pack from the vehicle completely, disconnect the main power connector, then remove the B+ wire from the battery terminal.
