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- .
For each vehicle. Refer to ⇒ Maintenance ; Booklet  for informa‐

tion regarding the battery.

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. If required, tighten

the mounting bolt to the tightening specification.

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 poles. If the battery terminals are dam‐

aged, contact with battery terminals clamps cannot be guar‐

anteed. When connecting the battery terminal clamps, always

from the repair manual in mind. Refer to ⇒  Electrical Equip‐

ment; Rep. Gr.  27 ; Overview - Battery . If the battery post

clamps are not correctly installed and secured, the wiring may

burn. Substantial malfunctions to the electrical system are a

consequence. Safe operation of the vehicle can no longer be

guaranteed.

2.3.1

“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 the battery

condition should always be confirmed through a battery test.

Refer to 

⇒ “2.4.3 Battery Load Test”, page 13

 .

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.

10

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.

2.3.2

“2-Color” Visual Indicator, Checking,

from 04/2008

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 »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 

⇒ “2.4.3 Battery Load Test”, page 13

 .

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 the battery

condition should always be confirmed through a battery test.

Refer to 

⇒ “2.4.3 Battery Load Test”, page 13

 .

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- .
