I just want to emphasize with other readers that the distinction between 'registering' and 'coding' is one of semantics: you still need the cable and software, it is just that registering is a single setting/click, whereas coding is a few more steps.

Coding is required if you change the type of battery you are putting in the vehicle. For example if you are going from NON AGM to AGM or if you go from 70ah to 90ah. Then you will need to code the vehicle to tell it the new battery type you have installed.

Registration is required whenever a battery is changed essentially to sync both battery and vehicle.

While everyone will not need to code their new battery (depending on whether or not they change the type), registration is always required.

Some will argue that they do not need to register the battery and their car has been fine for x amount of time, but failing to do so may result in compatibility issues or battery drainage issues.

I have to register a new battery next week. heizervr6's instructions are good and I have an operational INPA. My INPA dialog shows the same options as heizervr6 had showed.

Is it ok if I use "MSV 70.0 for N52" option for registering a battery for my N62 model (the 4.8i)? I don't see anywhere else to register a battery for a N62 model. I was able to use INPA (after selecting "MSV 70.0 for N52") today and get all the way to the battery registration option.

I'm not sure if there's a newer INPA (have v5) or scripts that I need to locate. Selecting "ME 9 for N62" just gives me a error messages in German that I can't make sense of.

(I will be making a coding change too for the increased "ah" of the new battery.)

Thanks

Brian, use Tool32 (Toolset32) for battery registration. INPA doesn't support registration for some models. Additionally, always choose your Engine type if you do use INPA.

Thanks! I see Tool32 in EDIABAS. Going to have to check it out...

Yep, you will find the registration process pretty simple as well.

Googling found me lots of info on registering other BMW batteries. I'm going to have to figure out from these PRG files (CDC_E70h / e70 / me9n62 / me962_2 / n62_tue) which have the STEUERN_BATTERIETAUSCH_REGISTRIEREN function (unless you happen to know ).

Do a file>>load>>MSV80.prg or MSV70.prg under the E70 folderand then under jobs you will find STEUERN_BATTERIETAUSCH_REGISTRIEREN and just run that job. It will tell you OKAY when it is complete.

I recently bought an Autozone Duralast H8-AGM battery to replace my original equipment AGM battery.

In the end I decided against the swap because no one at Autozone or the manufacturer of the battery (East Penn Manufacturing) was able to tell me the Amp Hour (AH) rating of the H8-AGM battery (see pics below)...

The AH number is what determines whether or not any coding needs to be performed. The problem with using one of the many formulas available for converting the Reserve Capacity Rating to Amp Hour rating results in values much higher than the 80ah-agm and 90ah-agm settings in Tool32 in EDIABAS. From what I know about AGM batteries, you don't want to over-charge or under-charge the battery ...

There are only 2 batteries I've found that have an AH rating of 92 stamped on the label from the factory. This value is close enough to the 90ah-agm setting and therefor require only registration and not coding (assuming AGM to AGM swap): the East Penn DEKA 9AGM49 ($175 and up) and one made by WorldSourceOne, group 49 AGM (available only through select distributors, $219 and up).

This brings me to my final question: in playing with the registration software, I inadvertently re-registered my old (current battery) ... Is this a problem? I'm told that what I did was just reset the date and mileage, but the alternator current output is still at the appropriate level for the age of the battery ... Anyone?
