Battery -A-

WARNING

Danger of injury! Observe warning notices and safety regula‐

tions 

⇒ page 2

 !

Caution

To prevent damage to battery -A- and vehicle, the following

instructions  relating  to  types  of  battery  must  be  observed

⇒ page 1

 .

1.1

Fundamentals for batteries -A-

To ensure long use of battery -A- , the battery must be checked,

serviced and maintained according to the instructions in this man‐

ual.
Apart from supplying energy for starting the engine, battery -A-

has other tasks: it acts as a buffer and supplies electrical energy

to the complete vehicle electrical system.

Note

Refer also to ⇒ Self-study programme  No.  234 ; Vehicle batter‐

ies .

1.2

Types of battery

General notes

Caution

The description for the following batteries -A- is for mainte‐

nance-free batteries -A- . Do not remove any stickers and do

not fill battery with distilled water. Only perform a visual check.

Refer to chapter, Checking battery 

⇒ page 5

 .

1.2.1

Battery -A- with magic eye

Maintenance-free battery -A- with liquid electrolyte (wet battery).

Caution

Do not remove any stickers and do not fill battery with distilled

water. Only perform a visual check. Refer to chapter, Checking

battery 

⇒ page 5

 .

1. Battery A     

1

Do not test or charge batteries -A- whose magic eye is “col‐

ourless/light yellow”. Do not slave/jump start the vehicle!
Danger  of  explosion  when  checking  and  charging  or  slave/

jump starting
These batteries -A- must be replaced.

This battery -A- is equipped with a magic eye. The magic eye

shows different colours to provide information concerning the lev‐

el of electrolyte and the charge level of the battery -A- .
Checking colour shown by the magic eye 

⇒ page 7

1.2.2

Absorbent glass mat (AGM battery)

Maintenance-free battery -A- containing electrolyte but without a

magic eye.
Lead-acid battery whereby the electrolyte is held in an absorbent

glass mat (AGM). Battery -A- is sealed and fitted with valves.
AGM is the abbreviation for “Absorbent Glass Mat”.
Due to the electrolyte being held in the mat, these batteries -A-

do not have a magic eye. Absorbent glass mat batteries are

identified by the abbreviation AGM on the battery -A- .

Note

Always replace an absorbent glass mat battery with another ab‐

sorbent glass mat battery.

1.3

Warning notices and safety regulations

1.3.1

Dangers involved in handling of batter‐

ies -A-

Recognition and avoidance of hazards
Batteries -A- can be dangerous. These dangers can be avoided

when the warnings on the battery -A- , in the ⇒  owner's manual

and in ELSA are observed.

2

♦ Untrained personnel, e.g. apprentices, trainees etc., may

only work on batteries -A- when supervised by a vehicle

mechanic/foreman or vehicle electrician/foreman.

♦ Acid is highly corrosive. Incorrect handling of batteries -A-

could expose staff to harmful effects caused by electro‐

lyte. Suitable measures must therefore be taken to ensure

that equipment/solutions etc. are available to neutralize

acid burns. A suitable solution is soap solution.

♦ Electrolyte leaks from the battery -A- can cause skin

burns, acid deterioration and corrosion on the vehicle.

This may damage safety relevant components on the ve‐

hicle.

♦ The gas which forms when charging and the gas which

may escape through vent valves is explosive. In extreme

cases, incorrect handling can cause the battery -A- to ex‐

plode as a result of gas leaks.

♦ Batteries -A- whose magic eye is “colourless/light yellow”

have to be replaced. Do not test or charge them and do

not slave/jump start the vehicle. Danger of explosion when

checking and charging or slave/jump starting

♦ It is prohibited to cause sparks through grinding, welding,

cutting operations and use naked lights in the vicinity of

batteries. Smoking is also prohibited. Sparks generated

by electrostatic charging must also be avoided. The vehi‐

cle body must be touched before touching the battery -A- .

♦ Only work on batteries -A- in well ventilated and suitable

rooms.

1.3.2

Safety markings on battery -A-

Safety markings on battery -A-
1 - Fire, sparks, naked light and smoking are prohibited when

handling batteries -A- . Avoid sparks as well as electrostatic

discharge when working with cables and electrical units.

Avoid short circuits. For this reason, do not place any tools

on battery -A- .

2 - Wear eye protection before commencing work on battery -

A- .

3 - Keep children away from acid and batteries -A- .
4 - Disposal: old batteries are classed as hazardous waste.

They may only be disposed of through a suitable collection

centre and only in accordance with respective legislation.

5 - Never dispose of old batteries in household waste system!
6 - Wherever batteries -A- are handled, there is a risk of explo‐

sion. Charging batteries -A- creates a highly explosive oxy‐

hydrogen gas mixture.

7 - Follow instructions concerning batteries -A- , in ELSA and

in ⇒  owner's manual .

8 - Risk of corrosion: Electrolyte acid is highly corrosive, which

is why protective gloves and eye protection must be worn

when working on battery -A- . The battery -A- must not be

tilted as acid could leak from battery vents.

Battery terminal connection

Caution

To prevent damage to the battery terminal clamps and battery

terminals, the following should be observed:

♦ The battery terminal clamps should only be fitted by hand

and without using force.

♦ Battery terminals should not be coated with grease.
♦ The battery terminal clamps should be fitted so that the

battery terminal is either flush with the clamp or protruding

from it.

♦ Once the battery terminal clamps have been tightened to

the specified torque, the threaded connections should not

be tightened any further.
