my OE was "Banner" not sure if they make batteries for the US too

I got to it, but thanks for the answer. To clear out one misconception in the thread, H8 (height) is a group size denomination, not a Battery type. There are H8 in both AGM and conventional. phonsalb, according to your specs you got the Bosch 49-850BAGM in H8 size for $164. EJT86 got a cheaper conventional Bosch H8-900B for $130.
I looked in my trunk and my 2013 M3 OEM is AGM H8 90 AH 900 CCA 160 RC so i am thinking of getting the same as yours. The funny thing is pepboys website would not allow me to browse all Bosch batts freely, I had to enter a car model. I actually had to enter Porsche 911 to be able to see the AGM H8 battery as it would not show for the M3.

I am guessing that's just the company that makes the unbranded oe sticker, not the battery. my 2013 has it too.

Lol nope blue top AGM 49-850 is what I got $130 😉
You can put 2013 M5 to look up the 49/H8 battery too

Good deal then. How did you manage to get $130, it is showing $164 now.

All I can really say is I got it at cost with a 20% discount and I “borrowed” a core

They can install it for free and you get $15 back for your old core but i've learned not to trust quick shops (and dealers !) to do anything carefully, esp sth i can do myself. Not sure why you are guarded about telling how you got it at cost. $153.99 is with their 30% discount.

Yea I installed it myself they can’t register the battery anyway, wasn’t hard just a lil tricky at times. Lol I’m guarded because the way I got it isn’t something that those people will want known. I said I used a hookup and worked it out it’s not something any guy off the street can get for that price otherwise I’d share.

ok fair enough, sounds like you made an offer they couldn't refuse.
only kidding lol. Sorry for being a tad nosy just didn't want to pass it up if it was all in the open. actually i think i got it..

I have a friend with a shop who supposedly gets the maximum discount at Pep Boys and he said they were $145 without core. With the common 30% discount they were in the $160+ range without core charge. You could try Walmart — I think they have an H8 a AGM for $139 without core. I would have bought one but my local store was out of stock.

I’d have def passed along the info to the forum if it was something everyone could take advantage of

The Everstart AGM from Wallmart is still out of stock. Finding the battery is half the trouble. After reading various threads and links around the subject it seems there are no easy known proven way to program the new battery and register it without paying a BMW garage or coder to do it.

A single INPA cable is not enough according to the following link you need a WIFI BMW ICOM A2+B+C hardware. EDIT : You can do it with just the INPA DCAN cable and NCSEXpert (if you new battery has a different current rating than the OEM 90 Ah and Tool32 to run an automated script that registers the battery.

The Carly and the Schwaben adapters have proven without a doubt to fail on cars post power module migration into the DME.

I wonder if other car brands owners are facing the same "anti trust" situation to register their battery or if this is just a BMW special.

When I changed batteries on my 08M3 about 4-5 years ago to an autozone H8 AGM, I did not register it but I did clear battery adaption through my Procede piggyback that handles the water meth injection. No problems since and I drive year round in NH where is is sometimes below 0F in winter. Changed battery last week as preventative maintenance since we are having a week straight of 0F weather. This time I used the Foxwell NT510, which with the bmw specific module will register a new battery in the maintenance menu. I used it on my E61 535xit at the same time and it confirmed registration.

If I had a different size battery like a smaller H6, then it would be best to recode for the significant change in AH. But the H8 AGM are all pretty close in specs — within about 5%.

[Rajmun340]

I agree with one owner who said it makes no logical sense to pay a stealer or tuner more than $35 to register a $190 AGM battery. Even if you are getting 2.5 years out of it instead of 4 due to not registering it (probably more anyway) then you're only loosing : (4-2.5)/4*190 = $71.25 from the premature replacement. Plus these batteries are almost always guarranteed free replacement for 30 months (=2.5 years).

About your Foxwell, cross checks with dealer tools showed that it fails to register the battery and gives a false positive message same as Carly. Go back to the menu and look at the battery history, if it still shows the old mileage registration and one less battery registration than it should, it did not register it. Same for Carly. Some advanced tuners have said you need full ICOM A2+B+C hardware not just INPA cable to be able to register new battery on newer cars w/o the power module. Over the years bmw evolved their power management system from a separate power module, then a micro power module and finally transfering these functions to the junction box + DME. There are probably more nuances and these third party tools quickly become obsolete if they used older bmw design white papers to develop them as there could be years of lapse for that internal bmw design documentation to leak outside.

here is a documentation describing the different BMW power management design architectures. It is dated 06-2011. But there could have been further minute but critical changes from 2011 to 2013 end of production year for the E9x M3

I’ll double check but it does not really matter to me since I have done this before without issue in 4-5 years as long as I clear battery adaption, which I can do. No way would I pay a dealer to touch my car. I let them while it was under warranty, but not after that.

I could not agree more with you about not letting a dealer touch the car now that it is no longer under warranty. Not (just) because they are greedy but because their techs are on average the worst and most careless people for your car. I learned that year after year, again and again and will never order a car new again so that i will never have to bring it to any dealership for service or work under warranty.

Do you use that procede tune chip to reset battery adaptation ? and what would you recommend to someone who wants to be able to do the same with minimum investment. I don't want Carly, or Foxwell. What is the required tuning tool setup and harware to be able to reset adaptation reliably ?

[pbonsalb]

The Procede is NLA so it’s not an option. Probably setting up an NCS laptop is the most capable affordable tool if you are good with computers — I am not.

https://www.bimmerforums.com/forum/f...ostic-Software

I had a friend with this software code EuroMDM into my 08M3 and do some other coding. Otherwise it’s Carly or BMWlogger or Foxwell NT510 for inexpensive tools that don’t require you to use a computer.

If your budget is much greater, you can look into much fancier tools. I don’t know which is best—snap on, Autel, Launch, autologic, autoingenuity, etc. These often require subscriptions and are more shop oriented.

I think the Foxwell NT510 is pretty good for the money as an all in one handheld.

I asked my SA and they want $150 for just coding the new battery.
About setting up a computer with NCS, what cable hardware do you then need ? Wouldn't that communication device cost as much as Foxwell or Carly ? I'm not bad on computers.

For $150 you could just buy a new battery for when the unregistered one prematurely dies

I don’t know enough to help but you can find answers in the link I provide or in that forum.

I am looking at :

-NCS expert (free software)
http://www.bimmerfest.com/forums/sho...d.php?t=879366

- INPA K+DCAN interface cable $17
http://www.uobdii.com/wholesale/bmw-...32rq-chip.html

-used laptop

To be able to reset battery adaptation for under $20 , hopefully that should reset the miles on the battery, since i am getting an AGM H8 49 battery the Ah spec is same as OEM not need to code the battery really.

Found this beginner tutorial for NCS, level of difficulty looks easy to moderate. Work flow is clear to me. I guess once the software is correctly installed on the laptop with the usb driver it's 90% of the difficulty.

http://blog.obdii365.com/2016/04/19/...for-beginners/

also I read this about different available ODBII interface cables, from my limited understanding the above cable is not enough to fully recode the battery but should be able to do as much as Carly or Foxwell for a small fraction of the price without the fancy interface.

Anybody with experience going down that path feel free to comment. I'll start a new thread with the goal to get this working and publish a DIY.
