BATTERY OFF SEASON STORAGE
Whenever 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.
NOTICE
Battery charge can be maintained by using a Polaris
battery tender or by charging once a month to make up
for self-discharge. Battery tenders can be left
connected to automatically charge the battery if voltage
drops below a pre-determined level.
BATTERY TESTING
Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
The 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”.
NOTICE
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.
Use a volt/ohm meter to test battery voltage.

LOAD TEST
CAUTION
To prevent shock or component damage, remove spark
plug high tension leads and connect securely to engine
ground before proceeding.
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.
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.
When equipped with dual batteries, each battery must be
disconnected and isolated before it can be tested using a
battery tester.
Authorized Polaris dealers/distributors are required to
use the conductance analyzer when testing 12V Polaris
batteries.
