Hyundai Tucson: Charge and Retest method after battery charge

Battery charge

Set battery charger to 'Auto Mode' (The Mode that charging current drops as the battery charges.) and charge battery until charging current down close to zero or the charger alerts you with an alarm when charge is complete.

(Minimum charging time recommended: More than 3 hours with Auto Mode that explained above)

• If battery is not fully charged, battery surface voltage will be high while the amount of current charged (CCA) in battery is low. If you measure the battery under this condition, tester may misjudge that battery sulfation occurred because the amount of current in battery is too low in comparison with battery voltage.

* Surface voltage: When battery is charged electrolyte temperature increases and chemical reaction become active resulting in an excessive increase of battery voltage.

It is known that it takes approximate one day to subside this increased surface voltage completely.

Battery Test after charge

Do not test battery right after the charge. Test battery after battery surface voltage has subsided as instructed in the following procedure.

(1) When battery charge is complete, install the battery in the vehicle.

(2) Put IG key to ON position and turn on head lamp with low beam, and wait 5 minutes. (Discharge for 5 minutes) (3) Turn off the head lamp and IG key, and wait 5 minutes. (Waiting for 5 minutes) (4) Remove +, - cable from the battery and test battery.

WARNING

When testing the vehicle with old diesel engines, the test result will not be favorable if the glow plug is not heated. Conduct the test after warming up the engine for 5 minutes.

Charging System Test Procedure

10. Press ENTER to begin charging system test.

11. The tester displays the actual voltage of mild hybrid starter generator (MHSG) Press ENTER to continue.

12. Turn off all electrical load and rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)

13. The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue

14. If the engine RPM is not detected, press ENTER after revving engine

15. The tester will conduct charging system test during loads off.

16. Turn on electrical loads (air conditioner, lamps, audio and etc). Press ENTER to continue

17. The tester will conduct charging system test during loads on

18. Rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)

19. The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.

20. If the engine RPM is not detected, press ENTER after revving engine.

21. Turn off electrical loads (air conditioner, lamps, audio and etc). Turn the engine off.

22. Charging voltage and charging system test results will be displayed on the screen.

    Shut off engine end disconnect the tester clamps from the battery. Refer to the following table and take the appropriate action as recommended by the Micro 570.
