Information
This “Technical Information” is intended as a summary guide to assist you with the following battery-related
topics:
•
Basic information on the battery, see ⇒ Technical Information 'Basic information',
•
documentation required, see ⇒ Technical Information 'Documentation is essential in the event of a
complaint',
•
recommended chargers and tools, see ⇒ Technical Information 'Recommended chargers and tools',
•
possible checks, see ⇒ Technical Information 'Checking the battery',
•
procedure if the battery has to be replaced/storing replacement batteries, see ⇒ Technical Information 'Procedure for replacing the battery' and
•
available reference material.
The critical points:
•
Quality assurance for battery life and battery performance and
•
Trickle charging in the workshop and by customers themselves
should also be generally improved as a result.

Basic information on the battery
Basic information on the battery
Characteristics: The AGM “starter battery”:
•
•
•
•
•
is absolutely essential for the “Auto Start Stop” function and recuperation,
is totally maintenance-free ⇒ no need to add water or check the electrolyte,
is leak-proof and dry,
is not sensitive to vibrations and shaking and
has a high cold-start performance.
Information
The battery has a limited service life.
The service life of the battery is affected by:
- the driving conditions for the vehicle and
- thus, by the care and maintenance of the battery (trickle charging, etc.).
⇒ If a charger is not connected in order to trickle-charge the battery when the vehicle is idle for extended
periods,
the battery life will be reduced considerably, thereby resulting in natural wear.
Please pass this information on to your customers.
Information
When working on the vehicle:
- using the PIWIS Tester or
- for work that takes longer than 15 minutes,
a charger must be connected in order to trickle-charge the battery.
Special features:
Information
The AGM battery:
•
is installed as standard in the vehicle and must not be replaced by a conventional “starter battery” and
•
must not be opened.
If the battery needs to be replaced, the following data must be entered in the gateway control unit using
PIWIS Tester II (under Maintenance/repairs - Change battery):

battery size.
The battery sensor:
•
is connected between the battery negative terminal and ground cable,
•
is an important part of the energy management system and
•
is used to measure battery variables (battery current, battery voltage and negative terminal
temperature) for vehicle electrical system diagnosis.
NOTICE
A battery charger for providing an external power supply or for jump-lead starting is connected directly to the battery in the
vehicle.
•
Damage to battery sensor.
•
Battery sensor sends incorrect battery values to the vehicle electrical system.
Þ
⇒
Always connect a battery charger for providing an external power supply or for jump-lead starting to the defined
Þ Workshop Manual '2X00INC8 Battery trickle charging'
connections in the engine compartment. ⇒
The battery is based on AGM technology (AbsorbedGlassMat):
•
•
Special micro-glass-fibre mats lie between the lead plates of the battery and contain all the
battery acid.
The sealed system is equipped with a pressure relief valve for the safe discharge of any gases.
Chemical processes:
The gas produced during charging is transferred through the pores in the glass-fibre mat to the
negative electrode, where it is converted back to water.
⇒ Water loss is impossible during normal operation.
Documentation is essential in the event of a complaint
Documentation is essential in the event of a complaint
Documentation:
Information
If a customer complaint is received concerning topics relating to battery capacity and quality, the following
written documentation must be created before carrying out any other work:
1. Create a VAL (Vehicle Analysis Log) and attach it to the job ⇒ charger required to trickle-charge the
battery.
2. Document the following points and attach them to the job.
