Volkswagen Polo Service & Repair Manual: 3-Color Visual Indicator, Checking
WARNING
| Risk of injury. Follow all Warnings and Safety
Precautions. Refer to
→ Chapter „Warnings and Safety Precautions“. |
|
| Visual Indicator General Information |
| Applies to all original equipment batteries with index “1J0”
, “7N0” and “3B0” and to all replacement batteries, part number
191 915 105 AB, and beginning with index “000 915 105 AX”. |
| The visual indicator shows the electrolyte level and the
battery state of charge. |
| To obtain an accurate reading, gently tap the charge
indicator with a screwdriver handle or rock vehicle slightly. By
doing this, the air bubbles that occur normally during battery
charging (even during vehicle operation) that adversely affect
charge indicator reading will be displaced. The visual indicator
will be more accurate. |
 Note
| Air bubbles can especially form under visual indicator when
a battery is charged, including when charged while driving. This
will cause an incorrect display. |
| The display is valid for only that one battery cell in which
the visual indicator is located. An exact assessment of battery
condition should always be confirmed by performing battery
charge test
→ Chapter „Battery Tester -VAS6161-“. |
| The visual indicator may be located on different locations
on the battery. |
| There Are Three Possible Color Indications: |
| »Green«: Battery is sufficiently
charged. |
| »Black«: Insufficiently charged,
less than 65% or discharged. |
| »Colorless or light yellow«,
battery must be replaced. |
WARNING
| Do not check or charge batteries that have a visual
indicator that is bright yellow. Jump starting must not
be used! |
| There is a risk of explosion during testing,
charging or jump starting. |
| These batteries must be replaced. |
