Battery replacement isn't cheap

[GuamX1]

What is the difference between registering and programming? My battery is dead and it costs $325 just for the battery at the dealer and it does not include registering or programming. I have a Carly app on my phone with the battery reset app. Can I do this? I installed an optima and when I drive the car after a while the battery gets weaker and would not start the car. I had to jump it to start. Its a 2008 BMW 128i convertible completely stock. Thanks

i think it only need reprogramming if you change type of battery, like normal to agm , or agm to normal ?

If you just replace the same part battery number by the same part number battery, why it would need programming ?

--> found somewhere

New battery + no registration = minimal/modest battery life
New battery + registration = maximum battery life

the computer of the car take in consideration that the battery is new, and will not overcharge it like an old one

I believe you can register a battery using the Carly app (aka BMW What). I think it has it as an in app purchase. Allows you to get a battery at the auto parts store or wallyworld and code/register it.

i paid 160 at bmw for white battery plus 30 bucks at an indy bmw shop to program it. now i have mhd so programming is free..

I just got a new battery installed while getting Dinan at the dealer. I think they charged me $150-$200 for the battery. Let me check my bill...

paid less than 120 i think with 5 years full warranty ...and progressive refund till 9 years

Cheap aftermarket battery and no registration? Let us know how that worked out for you.

Something tells me a lot of people that commented early on in this thread. Got a serious surprise when they asked their dealer about the expense of replacing the battery in their 135s..

You can buy and install the battery yourself, buy the Bimmercode app to code the battery and the adapter to allow coding for much cheaper than the labour cost.

Insanity to pay someone for this, also lazy.

Yeah even the location of the battery is much better than the E90s. I haven't replaced ine in my E88 but seems a lot easier since it's in the middle of the uder tray trunk and not hidden on the right side. 🙄
