It is recommended that this test is conducted at least 24 hours after the vehicle engine has been run or the battery charged to avoid the need of surface charge removal. If time constraints make this unacceptable then the surface charge must be removed.

Surface Charge Removal

A vehicle which has had its battery charged or been driven in a 24 hour period before the test, must have its surface charge removed.

Turn on the ignition but do not start the vehicle
Switch on the headlamps on high beam for a minimum 3 minutes
Switch off the headlamps
Wait a minimum of 5 minutes before recording test results for any battery measurements

Battery Test

The battery may be tested either on a bench or on the vehicle.

The battery condition must be checked in accordance with the battery test process utilizing an appropriate tester as outlined in the equipment section (Section 5) of this procedure.

NOTE: The midtronics code must be recorded on the form.

Any actions must be carried out in accordance with the table shown in the determining battery condition section (Section 6) of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage document.
