Volkswagen Polo Service & Repair Manual: Current Draw Test
WARNING
| Batteries that have a light yellow visual indicator
do not have to be tested or charged. Jump starting must
not be used! |
| There is a risk of explosion during testing,
charging or jump starting. |
| These batteries must be replaced. |
|
 Note
| Make sure the correct charging mode is set on the charger so
the current draw test is not inaccurate. |
| Battery Charger -VAS5095A-. Refer to
→ Chapter „Battery, Charging with Battery Charger -VAS5095A-“. |
| Battery Charger -VAS5900-. Refer to
→ Chapter „Battery Charger -VAS5900-“. |
| Battery Charger -VAS5903-. Refer to
→ Chapter „Battery Charger -VAS5903-“. |
| In order to receive an indication as quickly as possible of
the battery condition of discharged batteries, a conclusion can
be made during the charging process using the battery current
draw as to whether the battery should be replaced or charged
completely. |
Note
| In the case of the Battery Tester -VAS6161-, the current
draw test must always be conducted when the test result “conduct
current draw test” appears in the display. |
| Always Perform A Current Draw Test When: |
| the test result from the Battery Tester with Printer
-VAS5097A- shows the following: |
| 1 - |
Starting power sufficient |
| 2 - |
Starting power insufficient |
| 3 - |
Starting power very insufficient |
| 4 - |
Not able to test - charge the battery and test again |
| - |
and in cases in which the unit does not switch on (no LED,
no printout) |
| the test result from the Battery Tester -VAS6161- shows the
following: |
| 1 - |
Perform a current draw test |
| By checking a battery's current draw capacity during the
charging procedure, it can be determined in a short time whether
a partially discharged or severely discharged battery (refer to
→ Chapter „Severely Discharged Batteries“) can become
operable again by further charging. |
| When charging a battery, the battery temperature must be at
least ≥ +10 °C (+50 °F). |
| The charger must be able to deliver at least 30 A charge
current, for example as on the battery chargers -VAS5095A-,
-VAS5900-and -VAS5903-. |
| When charging using the Battery Charger -VAS5095A-, the
battery current draw must be measured with a current probe, for
example, Test Instrument Set - Current Clamp - 100A
-VAS6356/4A-. The Battery Charger -VAS5900- and the Battery
Charger -VAS5903- indicate the current draw on the device. The
Battery Charger -VAS5900- automatically performs the menu-
guided current draw test. |
| – |
Connect the battery to the battery charger and start the
charging process. |
| – |
Measure the battery charge current after five minutes. |
| When current draw A is greater than 10% of nominal capacity
Ah (for example, > 6.1 A at 61 Ah battery), fully charge the
battery and retest. |
Note
| On the Eos with two 6V AGM batteries, the charge current
must only be greater than 5% of the battery nominal capacity in
amp. As an example for Eos: the 50 Ah battery must have a charge
current greater than 2.5 A after charging for five minutes. |
| – |
Charge the battery completely when the charge current is
greater than 10% of the nominal capacity (note exception for Eos
in the note above). |
| – |
After resting the battery for two hours, perform a battery
test. Refer to
→ Chapter „Battery Test, Performing using Battery Tester
-VAS6161-“. |
| If the charge current is less than 10% of the nominal
capacity (two 6 V batteries in the Eos 5%) five minutes after
starting the test (that is, for a 50 Ah battery < 5A), then
replace the battery. Fill out the battery check sheet for
warranty and goodwill cases. |
