Yes make sure to code. I ran a 95 battery on 105 coded.. battery went toast in 6months.

Ok gurus, quick question. I swapped my battery out and I am still setting up my laptop to register the battery. Should I be really worried about making a few quick trips around town in the car. I am going from AGM battery to AGM battery and from 80 AH to 90 AH. I would think since my new battery has more AH I shouldn't really have to worry about over charging. Thoughts???

1/ No, don't worry about a couple of quick trips
2/ you are changing capacity - you need to code in addition to registering

[Gjohnson7]

Ok, I need a little help. I used Insta+ to register the new battery and I went through the screens and made sure to select that the battery was a different size, however it does not give me an area to add the new Amp Hours. I went from 80AH to 90 AH and I don't want to mess anything up.

When I research this, most posts and videos state to use NCSExpert to change the AH, however NCSExpert does not show a F10 model. All I see is E series. Am I missing something????

I got quoted 86 dollars from BMW to register my battery that I just installed yesterday.

Old was 92AH AGM.
New is 95AH AGM. 220 dollars out the door from autozone. The best duralast agm they can offer.

I am sure 3ah is not significant to a recode, even BMW stated this but wanted to at least register.

I've recently got increased discharge warning and charge battery warning, even after charging with my bmw charger/maintainer and driving the car so the battery finally took a shit.

The battery is 4 years old....can't complain at all. Did well.

Just stick with original battery and make sure you cod it.
If you don't wanna spend as much money on OEM battery. I personally only buy interstate battery
Best deal on interstate battery is in Costco.
Good luck

To clear up a couple of misconceptions on many battery threads:

1/ When coding there are only THREE options which will apply to F10s: 80Ah, 90 (sometimes I've seen 95 - not getting ESys out to check just now), 110Ah. There is no coding between values as close as 93 and 95 and it would never make a difference anyways.

Put your battery in the closest bucket - 80, 95 or 110. If you're changing buckets you need to re-code when you register. Generally in North America you'll have either the ~95 or the ~110. I don't think the ~80 was used very much.

You also use coding to switch charge plans between AGM and standard flooded batteries. We all started with AGM batteries (unlike the E series cars) and I think almost everyone is replacing with AGM.


2/ Registration and coding are completely different operations. REGISTRATION says you've installed a new one. CODING tells the car what size and type of battery is installed. Re-registering a battery doesn't affect existing custom coding or use the coding interface at all. You won't have to re-do custom coding if all you're doing is registering a new, identical battery.


3/ Simple registering can be done using many tools and many apps threw that function "in there". The MHD flasher app, for example, can register batteries. It might even be able to do it without a purchase. I think all of the common BMW coding apps can code AND register. ISTA+ includes "retrofit" functions (which I've never personally used) which combine the registration and coding to a different size. ISTA may very well wipe out custom coding if you use the retrofit function. If you want to re-code using a PC - F10s need E-Sys and an ENet cable, not ECSExpert.


4/ GJohnson - if you went from 80 to 90 you should re-code for the 90/95 Ah bucket. You could also use the ISTA retrofit function.

[Gjohnson7]

@Surly73

Thanks, that is really helpful info. I will give the retrofit option a look. Right now I am reinstalling my ISTA package. For some reason I can't get Ista P to recognize my car and I keep getting a message in Ista+ that the "Program could not initialized and needs to be repaired."

As I side note, on MHD you cannot register a new battery without purchasing a license. I saw multiple posts and even a video online stating this was possible, so since I was planning on tuning with MHD I went ahead a bought the MHD OBD2 adapter. I don't have any mods yet so I'm not ready to pull the trigger on buying a license and flashing a Tune and I have found out that the internet lies and I can't register my battery. Lol!

Nuts. I saw it in my MHD very early, before I purchased my license I thought. Oh well - I thought it was worth mentioning

[Gjohnson7]

No worries man. It is what it is.

Quick question. Do you happen to know what programs are worth installing on my laptop to work on my F10. It seems some of the programs I have downloaded from BimmerGeeks and other places won't actually work.

Right now I have an E-net cable and:

Ista+ 4.14.14
Ista-D 4.14.14
Ista-P Loader 6.4
Inpa
NcsExpert
NcsDummy
Tool32
E-Sys

Ok, did some research and found a quick way to code the battery using BimmerCode.


How to Code a new Battery with BimmerCode in under 5 Minutes

[bimawa535i]

Hi everyone. I went from a 90 Ah AGM to a 110 Ah Acid Lead Battery.

I wanted to change the battery type in the ECU before i registered it by Following the guide in the video above.

But there is no option for 110 AH

There's only 90 AH and 105 AH AGM. As shown in the video.

Does anyone know what the custom value would be for bimmercode to change it to 110 Ah non AGM?


RIGHT NOW in the interim I have it coded to 105Ah AGM and registered with the same.

[Surly73]

Use 105

[bimawa535i]

Thank you. Do you think there will be any issue with charging an h9 110ah non-AGM by selecting the 105Ah AGM?

[Surly73]

You should select the right type of battery. AGM and flooded do not have the same charging profile, the same resistance to permanent degradation due to being in a discharged state or the same aging profile.

You won't have any problems because of 105 vs 110, but you should pick the correct battery chemistry. Sorry I misunderstood the nuance of the middle of your post.

If Bimmercode cannot set the B105 or B110 battery type, you're better off with the 90Ah flooded setting, in my opinion. The capacity is incorrect, but all of the important charging and wear parameters are correct for flooded.

I've seen various resources online that imply that there are valid battery codes for flooded batteries greater the 90Ah, e.g.:

KLASSE_BATTERIE BATTERY TYPE
wert_00 value 00
80ah 80 ampere-hours
90ah 90 ampere-hours
110ah 110 ampere-hours
70ah 70 ampere-hours
55ah 55 ampere-hours
46ah 46 ampere-hours
70ah_agm 70 ampere-hours (agm)
90ah_agm 90 ampere-hours (agm)
60ah_agm 60 ampere-hours (agm)
80ah_agm 80 ampere-hours (agm)

(not that you asked, but I would not have personally downgraded an F- or G-chassis BMW to flooded...)

Ok I'll change it to 90ah. Thank you!

Would you mind helping me with the steps to code it correctly to 110?

I'm starting to think the same. I read and watched some videos saying there were cost and durability benefits to switching but I failed to take into account they were mostly talking about the smaller cars.

Hey guys, so i just replaced my battery from AGM 90ah to AGM 95ah. I registered it with bimmerlink, tried expermode in bimmercode to tell it its a 95ah but there was no option for that so i used 90Ah. The car feels different no more vibrations, everything is great EXCEPT the auto start-stop stopped working, and shows a "/" over the start-stop logo on the dashboard when its supposed to go off. Any ideas why?

The errors i got (not sure if they have anything to do with the battery)

Junction Box:
-002031 VSM_EVENT_VEHICLESTATE
-0020040 PDC: reset due to watchdog timeout
Central Gateway module:
-101008 non resolvable ambiguous routing- SG not in the SVT target value
-100104 HW weckgrund ZGW
100204 Message monitoring: no system context signal
Integrated chassis management:
-48276E Autosar- standardcore- non volatile memory- interdity
-482651 slip angle estimator inputs not valis SBS
-482656 slip angle estimator internal degradation due to SBS.

I would appreciate any advice

I checked with Costco today guy checked the info for my car he said H8 Battery fits my car I will change the amp hours to 90 AH and register it for a different type and capacity.

DON'T DO IT!!!!!!! Stick with the factory rating. There's a reason the factory installed a 105Ah battery and not the 95Ah! NEVER downgrade!!!

Super Start Platinum AGM Battery Group Size 95R H9 - 95RPLT
From O'Reilly is a perfect fit. You may also get some discount.
I replaced with it last year . No issues.

[razfrankel]

I will go to Costco today and buy the battery and then code it to a different size and register it maybe I will take it to the mechanic shop so they can do. I had the same issue in my e60 525i. I hope that will fix the no crank and no start issue.
