Battery Testing, using VAS 5097A

Battery Testing, using VAS 5097A

• In the voltage under load measurement, a start procedure at low temperatures is simulated. During the test, a high current is flowing; depending on the battery capacity, voltage must only drop to a minimum value specified by the battery tester.

• Following completion of test, voltage will remain low, and will recover slowly after a period of time.

• If the battery is faulty or only has a weak charge, the battery voltage drops very quickly below the specified minimum voltage.

• If the minimum voltage is not met, the battery must be replaced.

• Perform the test only one time. Repeating the test will not produce accurate results.

• The battery tester must cool off for approximately 30 minutes before it can test another battery.

Using the (VAS 5097 A), 12 V batteries with the follow cold cranking outputs can be tested:






• For information about the (VAS 5097A) operating instructions or the quick reference guide sticker on the device. Refer to the operating instructions.

Special tools, testers and auxiliary items required

• Battery Tester with Printer 5097 A (VAS 5097A)

• Using the battery tester (VAS 5097A), refer to the operating instructions.

Procedure

• The battery temperature must be at least 10 °C (50 °F).


There is a risk of injury from the battery acid.

• Follow accident prevention regulations when working with battery acid. Refer to => [ There is a risk of injury from the
battery acid. ] Lead Acid Battery Warnings and Safety Precautions.

• Wear protective eye-wear and clothing. Refer to => [ Protect against injury by using
protective eye-wear and clothing. ] Lead Acid Battery Warnings and Safety Precautions.

• On non maintenance free batteries, the sealing plugs must always be firmly tightened during the voltage under load measurement.

Risk of explosion on discharged battery with "visual indicator".

• If the "visual indicator" has no color or is light yellow, the battery may not be tested or charged. Jump starting must not be used! There is a risk of explosion during testing, charging or jump starting. The battery must be replaced.

- With the ignition turned off, disconnect the ground cable from the battery.

- On a battery with a "visual indicator", check its color display. Refer to => [ Electrolyte Level Color, Checking ] [1][2]Maintenance Free Battery.

- Determine the Cold Cranking Amps (CCA) according to the specifications on the battery in ampere (A) according to DIN and determine the (VAS 5097 A) adjustment range using the table. Refer to => [ Battery Testing, using VAS 5097A ].

- Set the CCA via the CCA selector switch - 5 -.





- Set the measuring range, 80 - 379 A or 380 - 499 A, using the ON/OFF-function switch - 6 -.

• Batteries with cold cranking output of 520 A according to DIN can be tested with the setting for 499 A according to DIN.

- Clamp the red battery tester test clamp "+" to the battery positive terminal.

- Clamp the black battery tester test clamp "-" to the battery negative terminal.

• Make sure the test clamps make good contact!

• Note TPL 2012182 for (VAS 5097 A).

- Using the sliding switch - 7 -, determine the test clamp connection point.





1. Direct connection to battery.

2. Connection to external test points in engine compartment.

- Check if the cold cranking output indicated on the battery matches the selected value on the battery tester.

- Press the start button - 4 -.





• Green Light Emitting Diode (LED) - 1 - lights up.

• The test program runs automatically.

• The tester result is input from the printer - 9 - after about 20 seconds.

• If the battery tester does not start (no LED lights up, no printout), the battery must be charged. Refer to => [ Battery, Charging ] Battery, Charging.

• If the red LED - 2 - lights up, the battery tester is connected with the terminals reversed.

• If the red LED - 3 - lights up, the battery cannot be tested. Replace the battery.

- Switch the battery tester off with the ON/OFF function switch - 6 -.

- Remove the test clamps.
