61 07 02 (875) Battery Master Document
Battery master document
All model series
Situation:
The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document summarises all important information about how the battery should be handled in the dealership.
Procedure:
The complaint "flat battery" can have various causes, most of which do not concern the battery itself. For this reason, replacing the battery will not usually lead to a lasting solution to the problem. The cause must be properly analysed in order to perform a repair that actually rectifies the cause.
Below you will find list of the available auxiliary materials. These must be worked through step-by-step to investigate the problem. The documents listed can be accessed via hotspots.
1. Fault analysis (energy diagnosis)
Fundamentally, the following causes are possible for a breakdown resulting from a flat battery or problems in the vehicle's electrical power supply:
Vehicle faults
- Battery defective / alternator fault
- Vehicle does not "go to sleep"
- Vehicle keeps being woken up
- Excessive standby current
Operating errors
- Side lights/parking lights/hazard warning flashers left on too long
- Terminal R/15 left on too long
- Unfavourable driving profile (e.g. extremely short distances)
- Unfavourable usage profile (e.g. immobilisation period too long, use of auxiliary consumers)
In event of a "dead battery" complaint, the energy diagnosis procedure must be followed for E65, E66, E67 from model year 03/2004 and for E60, E61, E63, E64, E81, E82, E87, E90, E91, E92, E93, E70, E71, E72, R55, R56, R57, R60, F01, F02, F03, F04, F07, F10, F11, RR4.
Text search in ISTA or path: Function Structure > 03 Body > Voltage supply > Energy diagnosis
IMPORTANT:
The prerequisite for invoicing a battery through the warranty channel is to work through the testing procedure
Energy diagnosis through to the diagnosis result:
- Show cause
- Show help instructions
- Show corresponding diagnosis code
Exceptions are:
- Obvious battery damage and leakage
Use the correct defect code in such situations (61 21 00 49 or 61 21 00 01).
- Use of BMW Group Mobile Service and battery replacement on site to restore customer mobility as quickly as possible.
NOTE: The aim of energy diagnosis is to identify the most probable cause for a breakdown caused by a flat battery or for problems in the vehicle's electrical power supply. The causes listed above are stored in energy diagnosis.
- For vehicles with automatic engine start-stop system, if this function is not fully available: If the procedure instruction "MSA power management" appears, the battery must be replaced. In this case use defect code 61 21 08 98.
NOTE: To enable the applicant to use the correct defect code, make sure that both the customer's statement and the diagnosis results are adequately documented. These must be made available to the applicant.
For all other model series
For model series that do not have energy diagnosis, the customer should be interviewed to make sure that the operating errors described above can be ruled out as the cause of the battery discharging.
2. Standby current measurement

For E65, E66, E67
Path: Complete vehicle > Body > Voltage supply > Alternator
4. For F10 vehicles: as from 06/2010 there will be an OnBoard diagnosis for assessing the battery condition.
5. When the battery is replaced For E65, E66, E67 always, for E60, E61, E63, E64
and E81, E82, E84, E87, E89, E90, E91, E92, E93, E70, E71, E72, R55, R56, R57, R60, F01, F02, F03, F04, F07, F10, F11, RR4
- Providing an intelligent battery sensor (IBS) is fitted (depends on vehicle equipment)
Register the new battery using the BMW diagnosis system.
IMPORTANT: If the new battery is not registered, incorrect readings may appear in the display of the on-board computer due to old data in the power management system (check control message "Recharge battery" appears even though the battery is new).
Only E65, E66, E67, F01, F02, F03, F07 and vehicles with SA536 (auxiliary heating), intelligent generator control or automatic engine start-stop function
NOTE: Only AGM batteries should be installed in these vehicles.
6. Recharging the battery
The battery may only be recharged with a battery charger that has been approved by BMW and that has a constant charging voltage of 14.8V.
If possible, the battery temperature should be between 15 °C and 25 °C during charging.
Under these conditions, the battery is adequately charged when the charge current drops below 2.5 amps.
If the battery is recharged at lower temperatures, the process should not be ended until the charge current drops below 1.5 amps. On vehicles with IBS, recharging the battery directly at the battery terminals could lead to a misinterpretation of the battery condition and even unwanted Check Control messages or fault entries.
If the battery is recharged while it is installed, it must be recharged using the jump start terminal points, whenever jump start terminal points are provided in the engine compartment (all vehicles except R55, R56, R57, R60).
Only then can you be sure that recharging is correctly recognised by the vehicle electronics on vehicles with intelligent battery sensor (IBS).
For R55, R56, R57, R60: These vehicles do not have any jump start terminal points in the engine compartment.
On these vehicles, the positive terminal of the battery charger must be directly connected to the battery. On vehicles with a petrol engine, the negative terminal can be connected to the lifting eye (suspension lug) on the transmission and on vehicles with diesel engines to a flange on the engine bearing block on the engine.
