Visual Inspection  
WARNING  
Risk of injury. Follow all warning messages and safety pre‐  
cautions. Refer to  
⇒ “1.3 Warnings and Safety Precautions”, page 3 .  
Before any extensive measurements are taken, visually inspect  
the exterior of the battery, the connections, and the secure in‐  
stallation of the Battery - A- .  
Caution  
♦ An improperly secured Battery - A- can lead to damage.  
♦ Excessive vibration due to an improperly secured battery  
will reduce the battery service life, and the battery hold-  
down bracket could damage the battery housing and lead  
to electrolyte leakage.  
♦ Make sure the Battery - A- is secure. Tighten the mounting  
bolt to the tightening specification, if necessary.  
Visual Inspection Points  
♦ Damage to the battery case. Acid can leak out if the case is  
damaged. Battery acid that has leaked out can cause severe  
damage to the vehicle. Acid that has leaked onto any part of  
the vehicle should be immediately treated with acid neutralizer  
or soap solution.

♦ Damage on the battery posts. If the battery terminals are dam‐  
aged, contact with battery terminals clamps cannot be guar‐  
anteed. When connecting the battery terminal clamps, always  
keep the tightening specification for the corresponding vehicle  
from the repair manual in mind. Refer to ⇒ Electrical Equip‐  
ment; Rep. Gr. 27 ; Battery . If the battery post clamps are not  
correctly installed and secured, the wiring may burn. Substan‐  
tial malfunctions to the electrical system are a consequence.

3-Color Visual Indicator, Checking,  
through 03/2008  
WARNING  
Risk of injury. Follow all warning messages and safety pre‐  
cautions.  
Refer  
to  
⇒ “1.3 Warnings and Safety Precautions”, page 3 .  
Visual Indicator General Information:  
The visual indicator provides information concerning the electro‐  
lyte level and the Battery - A- charge level.  
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. Thereby, the color indicator of the visual indi‐  
cator is more accurate.  
Note  
♦ Air bubbles can form under the visual indicator, especially if a  
Battery - A- was recharged or if the Battery - A- was charged  
while driving. These bubbles may cause the visual indicator to  
read inaccurately.  
♦ As the charge indicator is located in a single cell, the indication  
is only valid for that cell. An exact assessment of battery con‐  
dition should always be confirmed by performing battery test.  
Refer to ⇒ “2.6.3 Battery Load Test”, page 18 .  
♦ The visual indicator can be installed at various locations on top  
of the Battery - A- .  
There Are Three Possible Color Indications  
♦ »Green«: the Battery - A- is sufficiently charged.  
♦ »Black«: the Battery - A- is partially charged, the charge level  
is less than 65% or discharged.  
♦ »No color/bright yellow«: the Battery - A- must be replaced.

Visual Indicator General Information  
with respect to the correctness of information in this document. Copyright by AUDI AG.  
The »green« visual indicator for the charge level indicator is no  
longer used for these Batteries - A- . Only »black« or »no color or  
bright yellow« are used.  
The visual indicator shows the Battery - A- electrolyte level.  
It is no longer possible to read the Battery - A- charge level using  
the visual indicator. It is necessary to perform a battery test. Refer  
to ⇒ “2.6.3 Battery Load Test”, page 18 .  
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. Thereby, the color indicator of the visual indi‐  
cator is more accurate.  
Note  
♦ Air bubbles can form under the visual indicator, especially if a

read inaccurately.  
♦ As the charge indicator is located in a single cell, the indication  
is only valid for that cell. An exact assessment of battery con‐  
dition should always be confirmed by performing battery test.  
Refer to ⇒ “2.6.3 Battery Load Test”, page 18 .  
♦ The visual indicator can be installed at various locations on top  
of the Battery - A- .  
Two Visual Indicators Are Possible  
♦ »black«: the electrolyte level is OK  
♦ »No color or light yellow«: electrolyte level too low. Replace  
the Battery - A- .

2.6.5  
Battery Load Test Results  
By placing the battery under a strong load during the Battery - A-  
load test, the battery voltage will be reduced.  
♦ If the Battery - A- is good, the voltage drops only to the speci‐  
fied minimum voltage.  
♦ If the Battery - A- is defective or weakly charged, the battery  
voltage will drop very quickly to below the specified minimum  
voltage.  
♦ After testing, this low voltage level is maintained for a lengthy  
period and only increases again slowly.  
♦ Only perform the test once. Repeating the test will not produce  
accurate results.  
♦ In order to be able to test another/additional Battery - A- , the  
-VAS5097A- must cool down for approximately 30 minutes for  
the test result to be correct.

Depending on the test results -VAS5097A- (refer to  
⇒ “2.6.7 Test Result Evaluation”, page 22 ), 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 be‐  
come operable again by further charging. Refer to  
⇒ “3.6 Severely Discharged Batteries”, page 57 .  
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 cur‐  
rent, such as on the -VAS5095A- / -VAS5900- / Battery Charg‐  
er - 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.  
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.
