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