Current Draw Test: Notes

WARNING:

Do not check or charge a Battery -A- when the visual indicator has >>no color or is bright yellow<<. Jump starting must not be used!

There is a risk of explosion during testing, charging or jump starting.

These Batteries -A- must be replaced.

Make sure the correct charging mode is set on the battery charger so the current draw test is not inaccurate.

:VAS5095A . Refer to BATTERY, CHARGING WITH Battery Charger .
:VAS5900 . Refer to Battery Charger .
:VAS5903 . Refer to Battery Charger .

In order to receive an indication as quickly as possible of the battery condition of discharged Batteries -A-, a conclusion can be made during the charging process using the Battery -A- current draw as to whether the Battery -A- should be replaced or charged completely.

NOTE:

In the case of the :VAS6161 , the current draw test must always be conducted when the test result "conduct current draw test" appears in the display.

The current draw test should always be performed if the test using the :VAS5097A had the following results:

Starting power sufficient
Starting power insufficient
Starting power very insufficient
Cannot be tested - charge the Battery -A- and perform the test again
:VAS5097A does not turn on (no LED, no printout)

Depending on the test results :VAS5097A (refer to TEST RESULT EVALUATION ), additional test steps or work for a clear evaluation of the battery charge must be made.

By checking a current draw capacity on a Battery -A- during the charging procedure, it can be determined in a short time whether a partially discharged or severely discharged Battery -A- can become operable again by further charging. Refer to SEVERELY DISCHARGED BATTERIES .

Test Prerequisites

When charging a battery, the temperature of the battery must be at least 10 °C (50 °F).
The charger must be able to deliver at least 30 A charge current, such as on the :VAS5095A /:VAS5900 /Battery Charger:VAS5903 .
When charging with the :VAS5095A , the Battery -A- current draw must be measured using a current probe (:VAS6356/4A ).
The :VAS5900 and the :VAS5903 indicate the current draw.
