Load Test
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:
• Remove 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.
• Using a wire brush or knife, remove any corrosion from
the cables and terminals.
• Make sure that the electrolyte is at the proper level. Add
distilled water if necessary.
• Charge at a rate no greater than 1/10 of the battery’s
amp/hr capacity until the electrolyte’s specific gravity
reaches 1.270 or greater.
• Store the battery either in the machine with the cables
disconnected, or store in a cool place.
NOTE: 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.
Charging Procedure
1. Remove the battery to prevent damage from leaking or
spilled acid during charging.
2. Charge the battery with a charging output no larger than 1/
10 of the battery’s amp/hr rating. Charge as needed to raise
the specific gravity to 1.270 or greater.
3. Install battery in vehicle with positive terminal toward the
front. Coat threads of battery bolt with a corrosion resistant
dielectric grease.
4. Connect battery cables.
