Alternative Method To Dissipate The Battery Surface Charge
1. 1. Leave the battery to stand for a minimum of six hours without charging or
discharging or remove the surface charge through partial loading as follows:
Turn the ignition key to position II and switch on the headlamps (main beam),
heated windshield (if equipped), heated rear window (if equipped) and the heater
blower motor (position II). Leave the vehicle in this condition for a minimum of 60
seconds to dissipate the battery surface charge.
Turn the ignition key to position 0 and switch off the headlamps, heated windshield
(if equipped), heated rear window (if equipped) and the heater blower motor.
Leave the vehicle in this condition for a minimum of five minutes before testing
battery condition.
Battery Test
NOTE: Using the Micro390 Battery Tester: To fully determine battery condition once the
surface charge has been dissipated, the Micro390 battery tester must be used. For the
Micro390 battery tester to operate, it requires a minimum of 5.5 volts charge to be
present on the test battery. Therefore, if the Micro390 does not operate when connected
to a test battery, then a charge of less than 5.5 volts is present. In this instance, the
battery must be charged in line with the battery charging instructions prior to testing. In
the event of a conflict of results between the charge eye indicator and the battery tester,
the battery tester result must always be used. The charge eye indicator is for guidance
only.
1. 1. Remove the battery.
REFER to:
Battery
(414-01 Battery, Mounting and Cables, Removal and
Installation).
2. 2. Connect the battery tester to the battery.
Connect the red clip to the battery positive (+) terminal and the black clip to the
battery negative (–) terminal.

NOTE: The label affixed to the top of batteries progressively from 06/1998 identifies
the battery CCA rating. Remove the battery if the label is obscured.
