LOAD TEST
CAUTION: To prevent shock or component
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
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.
OFF SEASON STORAGE
To prevent battery damage during extended periods
of non-use, the following basic battery maintenance
items must be performed:
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. NOTE: Do not
get any of the baking soda into the
battery or the acid will be neutralized.
GUsing a wire brush or knife, remove any
corrosion from the cables and
terminals.
GMake sure that the electrolyte is at the
proper level. Add distilled water if
necessary.

NOTE: Stored batteries lose their charge at the rate
less than 1.115
of 1% per day. Recharge to full capacity every 30 to
60 days during a non-use period. If the battery is
stored during the winter months, electrolyte will freeze
at higher temperatures as the battery discharges.
The chart below indicates freezing points by specific
gravity.
