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
G. Take a test voltage reading while still under load after 15 seconds, then
immediately remove the load.
H. Use Minimum Voltage (page 6–32)
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.
