Well you're incorrect..

On E89s everytime the battery is changed the change needs to be registered to allow the DME to work out best to manage that battery..

Additionally if you change the capacity of the battery you need to code it..that is allow the DME know that the capacity and maybe type has changed.

If you don't code or register the new battery as appropriate, it will still work, but you won't get the best life and performance out of it.

Ok, prove that statement please, I mean PROVIDE DOCUMENTED PROOF. I say again, if the spec is the same, the battery is the same. This requirement is based on the ecu knowing what to charge and for how long. If its identical... what would you change aside from the date and serial number, and as most people will tell you is to simply put a line of zero's. Mainly because it's almost impossible to find a serial number on a battery and mostly because the ecu doesn't care what the serial number is.
If you ever think I'm off my rocker.. Just put me back in it and walk away... It's the kindest thing

Notice! Register battery replacement
After installing a new battery, the service function 'Register battery replacement' should be run. The battery replacement has to be registered in order to tell the power management system that a new battery has been installed in the vehicle. If the battery replacement is not registered, the power management will not function properly, with the result that Check Control messages may be displayed and functions limited by individual electrical consumers being switched off or having their power consumption reduced, for example.

and..

Proper operation of all of these safety and convenience functions requires a battery that conforms with specifications and that is properly registered in vehicles with energy management systems (IBS, power module).

Vehicles with energy management systems (IBS, power module): Register battery exchange.

The vehicle electrical system is informed about the vehicle battery characteristic data, such as type, size, age and current power capacity. Therefore, there will always be only one work scope provided that is permitted by the current status of information.

When installing a new vehicle battery, the battery must be registered and thus must also be registered with the vehicle electrical system.

Diagnosis system:

Register battery exchange.

Service functions
Body
Voltage supply
Register battery exchange
When retrofitting, a more powerful battery may be used. Standard batteries may always be replaced by AGM batteries with the same specifications.

When installing a battery of a different size or a different battery type, this change in vehicle data must be programmed into the vehicle data in accordance with specifications.

Programming system:

lovely, now where does it say .. "even if the replacement battery is absolutely identical" you have to waste a part of your life telling the cpu its identical in every way ? i feel like Dave Lister feels when he talks to Rimmer. Are you going to put me on a charge ? No wait .. not a charge, :headbang:
as TIS so elequently explains.. "intelligent battery sensor and battery" IF its intellegent WHY you have to tell it ?

i wonder... if you cover a seat with an identical seat cover do you have to tell carly ? or the wife, or the bank manager , or the bad taste god?
see below for proof of my existance.
as for BMW saying register it - i rather suspect a VISIT TO THE DEALER is imagined - ca ching..

Has the pope got a balcony ?
Does it count if you just scan irrelevent documentation to prove god exists ? :poke:

should i get out more ? should i get out less ?

ahh i hear the frantic banging of keyboards from here :rofl:

poking aside - i see absolutely no mention of identical battery fitting instructions, why would there be ?

TELL YOU WHAT. this is a challenge to all OCD folk ( might be one or two on here i suspect)
when you replace your battery next with IDENTICAL specifications, run it for a MONTH without telling carly or his mates like TIS, and measure battery (SOC) capacity THEN tell the computer you have a NEW shiny identical battery and after another month see if there is a differance.

Would BMW expect you to fit a different amperage battery? Probably not
Do they expect replacing with the same? Probably, so they give instructions to register it.

You're wasting your time (as I have)..probably in the same 60 cigarettes a day never did my Dad any harm etc..since he can't read or maybe English comprehension wasn't his strong point... :poke: :headbang:

Key point for all others ..pls register a replacement battery, and if its different capacity code it then register it! :thumbsup:

Sharing some knowledge for old-folks scared of zappy electrons as it is close to me everyday at work (no wonders EVs are not welcomed...):
-A new battery, even if identical make, model and capacity is in fact NOT the same, if it were then the old battery would not need changing as it would hold charge and crank just fine!
-The old battery has suffered three things: a loss of capacity, an increase of resistance (lower cranking amps) and an increase in self-discharge (dies on it own when car is parked)
-The car continuously adapts to that evolution and will adjust by keeping SOC to a higher/lower/narrower level and/or charge more gently and such, hence the need to tell it a new battery has been installed so it can reset and re-learn, sorry things have changed since the 80s :driving:

Some additional background infos for interested members. Ignorers should ignore it! :headbang:

Registering means resetting & updating most of the (old) battery statistics collected inside of the DME.

You asked for proof. You were given proof. It’s up to you what you do with it.

If you don’t like it. Then don’t follow it. Simples. Anyone else it’s there for a reason.

For a 5 min solution, why risk a £100-200 battery. We know how fussy the car can be over battery health.

I believe Mr Road Warrior's experience is with the E85, which does not have the same IBS and therefore doesn't need all this coding. The E89 does.
However, don't worry about it because if he does try his own suggestion then in a month he will have reached the edge of the world and fallen off. :D

I don't think so.

The whole IBS stuff came up with the start/stop functionality. The DME has to know the constitution of the car's battery before switching off the motor at a ( i.e.) crossing.

That's the reason why the DME is tracking each battery activity: loading, unloading, temperatures, histories etc.
It calculates the aging process in the background 24/7 and at least gives an advice on the dash to get it renewed after an individual time of usage.

If you don't reset this history, dashboard messages may reappear even with a new battery, as the system requires some time to adapt the condition of the new battery (SOC & QOC). It's indeed a learning curve, which again will arise over time.

It's not so critical for "our" E89's, as there is no start/stop function implemented on the 6-pot engines. The 4-pot's indeed were delivered with this functionality and require this "reset"/registering.

My 2013 28i doesn't have start / stop. So is this something that a previous owner has coded out?
