AR54.10-P-1129-01A Check Battery

DANGER: Risk of explosion caused by oxyhydrogen gas. Risk of poisoning and caustic burns caused by swallowing battery acid. Risk of injury caused by burns to skin and eyes from battery acid or when handling damaged lead-acid batteries

No fire, sparks, open flames or smoking. Wear acid-resistant gloves, clothing and glasses. Only pour battery acid into suitable and appropriately marked containers.

Whenever possible, carry out the test with the battery installed and connected. Do not clip on tester at the jump start or charging support point but always directly at the battery.

Battery tester
gotis://E_15/54_02.0

All test steps and entries must be performed thoroughly, otherwise the test result will be distorted.

Test prerequisites:
^ Tester with software release 2.0
^ Ignition off
^ Rotary light switch in position "0"
^ Audio component (e.g. radio) switched off
^ Battery voltage higher than 12.4 V
^ Good contact of the tester on the battery

If the message "Surface voltage" is displayed during the test, the tester has detected that the battery voltage is apparently too high. This increased voltage can be reduced as follows:
^ Battery installed: Decrease increased voltage as per the specifications of the tester (e.g. switch on driving lights).
^ Battery removed: reduce increased voltage using a suitable volt/amp(s) tester (load battery for approx. 60 s with 20 A to 30 A amps).

As an example, the test procedure for passenger cars is described below.







1. Clip tester (1) on to battery.
Once the tester is connected the current measured battery voltage is displayed for approx. 2 s. If a so-called "System noise" is detected by the tester, check whether all consumers are switched off and wait (for approx. 2 min), until the quiescent current is minimized and the bus systems are switched off.







2. Follow the menu and select according to the situation:
^ In vehicle (battery connected to on-board electrical system)
^ Not in vehicle (battery disconnected from on-board electrical system)
Confirm selection with "Enter".







3. Follow the menu and select according to the situation:
^ 12 - 114 AH (battery capacity 12 - 114 Ah)
^ 115 AH > (battery capacity ≥ 115 Ah)
Confirm selection with "Enter".







4. Follow menu and select battery type:
^ Normal
^ VRLA
Confirm selection with "Enter".







5. Follow the menu selection and select the test standard for the cold cranking amps.

The test standard is printed on behind the specification of the cold cranking amps.
If the imprint of the test standard is not available, select the cold cranking amps "EN".
Example: 12 V 46 Ah 420 A -> Select EN.
Confirm selection with "Enter".







6. Read off cold cranking amps and enter in tester.
Example: 12 V 46 Ah 420 cold cranking amps: -> 420 A. Confirm input with "Enter". The battery test starts after confirmation of the cold cranking amps entry.
The test result or one of the following messages appears after approx. 15 s:
^ Test code -> Step 7
^ Vehicle model -> Step 9
^ Temperature > 0 °C /< 0 °C -> Step 10
^ Before charging / After charging -> Step 11
^ Surface voltage DETECTED (see above)

7. Read off test code with "Enter" and continue accordingly:
^ "Battery in good condition":
No further measures required.
^ "Charge and test":
Fully charge battery and retest (battery voltage > 12.4 V).
^ "Replace battery":
Replace battery if this message appears.

8. Print out test code and file in a tamperproof manner.







9. Follow the menu and select test mode:
^ Cars
^ Taxi

Confirm selection with "Enter".







10. Follow the menu and select test mode:
^ > 0 °C
^ < 0 °C

Confirm selection with "Enter".
If this message appears, the battery condition cannot be evaluated.







11. Follow the menu and select test mode:
^ BEFORE CHARGE
^ AFTER CHARGE

Confirm selection with "Enter".

12. Perform additional menu-assisted function (e.g. starting several times and switching on consumers).
Only in taxi test mode if displayed in menu.
