ELECTRICAL
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 charts and Load Test.
NOTE: Lead-acid batteries should be kept at or near
a full charge as possible. Electrolyte level should be
kept between the low and full marks. 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.
Specific Gravity Test
A tool such as a Battery Hydrometer (PN 2870836) can be used
to measure electrolyte strength or specific gravity. As the
battery goes through the charge/discharge cycle, the electrolyte
goes from a heavy (more acidic) state at full charge to a light
(more water) state when discharged. The hydrometer can
measure state of charge and differences between cells in a multi-
cell battery. Readings of 1.270 or greater should be observed in
a fully charged battery. Differences of more than .025 between
the lowest and highest cell readings indicate a need to replace
the battery.
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.
