MAINTENANCE-FREE BATTERY

Specifications

Battery Removal/Installation

1. Open the left and right side door panels. Remove the

hood.

2. Remove the exhaust silencer.

3. Remove the battery heat shield.

4. Remove the rubber strap. Disconnect the RED(+)

cable first, and then the BLACK(-) cable.

5. Installation is the reverse of removal. Install the

BLACK(-) cable first, and then the RED(+) cable
during installation.

Battery Preparation

NOTE: Do not service the battery unless it will be put
into regular service within 30 days.

Some original equipment and service batteries are
supplied with acid packs.

1. To fill the dry battery, remove the vent cap from the

battery and the sealing cap from the acid pack.
Carefully tip the acid pack into the battery vent ports.

2. Set battery aside and allow it to cool and stabilize for

at least 30 minutes. Reinstall the battery vent cap.

NOTE: This is the last time that electrolyte should be
added.

3. Charge battery at 1/10 of its amp/hour rating.

Example:1/10 of 9 amp battery =.9 amps, 1/10 of 14
amp battery = 1.4 amps, 1/10 of 18 amp battery = 1.8
amps (recommended charging rates).

4. Check specific gravity of each cell with a hydrometer

to ensure each has a reading of 1.270 or higher.

5. Install vent cover.

NOTE: Once the vent cover is installed, the battery is
sealed. Do not remove the cover.

Charging Procedure

If battery voltage is 12.6 VDC or less, the battery may
need recharging. When using an automatic charger, refer
to the charger manufacturer’s instructions for recharging.

Do not exceed 10 amps when charging the battery.

NOTE: Charge the battery using an automatic
charger that will not exceed 14.6 VDC. An automatic
charger will signal when charging is complete.




Allow the battery to stand disconnected for several
hours after being properly charged. If the voltage
drops below 12.6 volts, charging was ineffective or the
battery needs to be replaced.

Battery Charging Reference Table

NOTE: Follow the charger instructions supplied by
the manufacture regarding the order or connections,
switch positions and when to connect the charger to
an outlet.

Battery Testing

Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.

Following are two tests which can easily be made on a
sealed Maintenance Free battery to determine its
condition: OCV Test and a Load Test.

OCV - Open Circuit Voltage Test

Battery voltage should be checked with a digital
multitester. Readings of 12.6 volts or less require further
battery testing and charging. See the following chart and
“Load Test”.

NOTE: Maintenance Free batteries should be kept at
a high state of charge during storage. If the battery is
stored or used at a low state of charge, hard crystal
sulfation will form on the plates, reducing the
efficiency and service life of the battery.

NOTE: Use a volt/ohm meter to test battery voltage.

Load Test

A battery may indicate a full charge condition in the OCV
test, but still may not have the storage capacity necessary
to properly function in the electrical system. For this
reason, a battery capacity or load test should be
conducted whenever poor battery performance is
encountered.

To perform this test, use a load testing device that has an
adjustable load. Apply a load of three times the ampere-
hour rating. At 14 seconds into the test, check battery
voltage. A good 12V battery will have at least 10.5 volts.
If the reading is low, charge the battery and retest.

WARNING

An overheated battery could 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.

Battery Conductance Analyzer

Conductance describes the ability of a battery to conduct
current. A conductance tester functions by sending a low
frequency AC signal through the battery and a portion of
the current response is captured, from this output a
conductance measurement is calculated. Conductance
testing is more accurate than voltage, specific gravity, or
load testing.

Authorized Polaris dealers/distributors are required to
use the conductance analyzer when testing 12V Polaris
batteries.

Battery Off Season 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.

NOTE: Battery charge can be maintained by using a
Polaris battery tender charger or by charging once a
month to make up for normal self-discharge. Battery
tenders can be left connected during the storage
period, and will automatically charge the battery if the
voltage drops below a pre-determined point.
