Current Draw Test

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.

Battery Charger: VAS5095A . Refer to BATTERY, CHARGING WITH Battery Charger .
Battery Charger: VAS5900 . Refer to Battery Charger .
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 Battery Tester with Printer : 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
Battery Tester with Printer : VAS5097A does not turn on (no LED, no printout)

Depending on the test results Battery Tester with Printer : 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 Battery Charger: VAS5095A /Battery Charger: VAS5900 /Battery Charger: VAS5903 .
When charging with the Battery Charger: VAS5095A , the Battery -A- current draw must be measured using a current probe (Test Instrument Set - Current Clamp - 100A: VAS6356/4A ).
The Battery Charger: VAS5900 and the Battery Charger: VAS5903 indicate the current draw.

Procedure

-- Connect the Battery -A- to the Battery Charger and start the charging process.

-- Measure the Battery -A- charge current after five minutes.

Test Result

The charge current must be above 10% of the nominal capacity 5 minutes after charging begins.

Example

With a 60 Ah battery, the charge current must be greater than 6 A 5 minutes after charging begins.

-- Fully charge the Battery -A- if the charge current is higher than 10% of the nominal capacity.

-- Let the Battery -A- sit for two hours and then perform the battery load test. Refer to BATTERY LOAD TEST .

If the charge current is less than 10% of the nominal capacity (less than 6 A for a 60 Ah battery) five minutes after starting the charging, then replace the Battery -A-. Refer to BATTERY, REMOVING AND INSTALLING .

-- In warranty and Goodwill cases, fill out the battery test sheet and keep it with the Battery -A-.
