Inspecting, Maintaining, and Testing the Battery (continued)
3. Do a high-discharge test with an adjustable load tester. This is a very reliable
means of testing a battery as it simulates the battery cold-cranking capacity.
A commercial battery load tester is required to do this test.
CAUTION
Follow the manufacturer's instructions when using a battery load
tester.
A. Check the voltage across the battery terminals before testing the battery.
If the voltage is less than 12.0 VDC, charge the battery before continuing
the test.
B. If you charge the battery, apply a 150 A load for 15 seconds to remove
the surface charge. Use a battery load tester following the manufacturer's
instructions.
C. Ensure that the battery terminals are free of corrosion.
D. Measure the electrolyte temperature of the center cell.
E. Connect a battery load tester to the battery terminals following the
manufacturer's instructions. Connect a digital multimeter to the battery
terminals
F. Apply a test load of 1/2 the cold cranking amperage rating of the battery;
refer to
Battery Specifications (page 5–37)
.
G. Take a test voltage reading while still under load after 15 seconds, then
immediately remove the load.
H. Use
Minimum Voltage (page 5–40)
to determine the minimum voltage for
the center cell electrolyte temperature reading.
I.
If the test voltage is below the minimum, replace the battery. If the test
voltage is at or above the minimum, return the battery to service.
