I know the thread is long, but all the info is there. The problem isnt because of not registering the battery, although you will not get optimal life/performance from the battery if you didnt register it. Not registering a battery isnt going to cause the BST cable to pop off or the battery to explode.

Bringing the thread back to life. If one doesn't spend stupid money on OEM, is resetting the battery adaptation via BT scan tool, the same as "registering" it?

Yep..here is what you have to follow:

Engine Module, Commands, Battery Replacement Adaption, Click Send Button

But that can only inherently tell the system that the same battery design and capacity has been installed.

Unless Ah valuation has been provided, it can only revert to what was originally programmed.

Now, going up in Ah (capacity) should be a non-issue. If the system wants to maintain the battery at about 80% SOC, and then put energy in, what it will end up finding out is that when it puts energy in, there is more capacity to put even more in. The SOC is determined by evaluation of voltage, which under load has to utilize an estimation for cell impedance in order to be correct (Vt=Voc-IR). If a smaller battery was installed, the logic should still cut out based upon SOC, but the conditions may be such that it causes overcharge conditions or puts too much energy in too quick.

Now I have a 135i, and Im just reading about the BMW batteries. I think mine is black, but Ill have to check. What Im trying to understand even after reading 18 pages is the actual difference between programming and registering... From there Ill go figure if the E8x needs it like the E9x.

Thanks!

Its the same for an E8x. If you go from lead acid to agm (white to black) you need to program. If you change capacity with the same style battery, you only register it.

Got it. BTW, AGM is a type of Lead Acid battery. The more accurate way to describe them is "Flooded" versus "AGM".

Anyway, thanks so much for the info and clarification, sure appreciate it!

Maybe wait somewhere else than behind the car?

What ended up happening to the creases in your rear bumper? Were you able to get them out? Any other damage?

The push bumpers on CHP cars are supposed to have a lot of cushion. Am kind of surprised that there was damage.

Good to know. Thanks for the info.

[regensburg94]

BUMP - very curious about the bumper ripples and how OP may have fixed them.

[regensburg94]

BUMP again.

heard about this before ut glad i read to keep it in my mind for when the time comes
