BATTERY OPEN CIRCUIT VOLTAGE TEST
(OCV)
Battery voltage should be checked with a digital
multimeter. Readings of 12.5 volts or less require further
battery testing and charging.
NOTICE
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, 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.

BATTERY LOAD TEST
NOTICE
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.
