Battery Testing - Polaris 2009 Trail Boss 330 Service Manual

3. Reinstall battery, attaching positive (+) (red) cable
first and then the negative (-) (black) cable. Coat
terminals and bolt threads with Nyogelt Grease
(PN 2871329).
4. Reinstall the holder strap.

BATTERY TESTING

Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
Following are three tests which can easily be made on
a battery to determine its condition:
Specific Gravity Test and Load Test.
SEALED LOW MAINTENANCE
BATTERY - - OCV - OPEN
CIRCUIT VOLTAGE TEST
Battery voltage should be checked with a digital
multitester. Readings of 12.8 volts or less require
further battery testing and charging. See charts and
Load Test.
NOTE: Lead-acid batteries should be kept at or near
a full charge as possible. If the battery is stored or
used in a partially charged condition, or with low
electrolyte levels, hard crystal sulfation will form on
the plates, reducing the efficiency and service life of
the battery.
NOTE: Use a voltmeter or multimeter to test batter
voltage.
OPEN CIRCUIT VOLTAGE
State of Maintenance
charge Free
100% 13.0V
75% Charged 12.80V
50% Charged 12.50V
25% Charged 12.20V
0% Charged less than 12.0V
* At 80_F
NOTE: Subtract .01 from the specific gravity reading at 40_ F.

BATTERY LOAD TEST
CAUTION:
damage, remove spark plug high tension leads
and connect securely to engine ground before
proceeding.
NOTE: This test can only be performed on machines
with electric starters. This test cannot be performed
with an engine or starting system that is not working
properly.
A battery may indicate a full charge condition in the OCV
test and the specific gravity test, but still may not have
the storage capacity necessary to properly function in
the electrical system. For this reason, a battery capacity
OCV Test,
or load test should be conducted whenever poor battery
performance is encountered. To perform this test, hook
a multitester to the battery in the same manner as was
done in the OCV test. The reading should be 12.6 volts
or greater. Engage the starter and observe the battery
voltage while cranking the engine. Continue the test for
15 seconds. During cranking the observed voltage
should not drop below 9.5 volts. If the beginning voltage
is 12.6 volts or higher and the cranking voltage drops
below 9.5 volts during the test, replace the battery.

BATTERY OFF- -SEASON
STORAGE
To prevent battery damage during extended periods
of non-use, the following basic battery maintenance
items must be performed:
Conventional
Lead / Acid
12.70V
12.50V
12.20V
12.0V
less than 11.9V
To prevent shock or component
GRemove the battery from the machine
and wash the case and battery tray
with a mild solution of baking soda
and water. Rinse with lots of fresh
water after cleaning.
GUsing a wire brush or knife, remove any
corrosion from the cables and
terminals.
GCharge at a rate no greater than 1/10 of
the battery's amp/hr capacity until
the voltage reaches 13.0 Vdc or
greater.
GStore the battery either in the machine
with the cables disconnected, or
store in a cool place.
