Low Maintenance Battery Installation
1. Clean battery cables and terminals with a stiff wire
brush. Corrosion can be removed using a solution of
one cup water and one tablespoon baking soda.
Rinse well with clean water and dry thoroughly.
2. Route the cables correctly.
3. Reinstall battery, attaching positive (+) (red) cable
first and then the negative (-) (black) cable. Coat
terminals and bolt threads with Nyogel® Grease (PN
2871329).
4. Reinstall the holder strap.
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.
Use a voltmeter or multimeter to test battery voltage.

Low Maintenance Battery Load Test
To prevent shock or component damage, remove spark
plug high tension leads and connect securely to engine
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:
1. Hook a multitester to the battery in the same manner
2. Engage the starter and observe the battery voltage
3. During cranking the observed voltage should not
