I need to replace the battery for my wife's loaded 2016 535i with pretty much every option, so I need to stay with an 105AH AGM battery. The original battery is a VARTA 105AH, 950A. Looking at realoem.com, the battery I need is a 105AH battery, part number 61212353814 which according to bmwpartspros.com, BMW has replaced with a new part number, 61-21-5-A40-E33

I've talked to bmwpartspros (Steve Thomas BMW) which is a few minutes from my house and they said that the only option they have is the 92AH battery, part number 61-21-5-A40-E29. They told me that BMW has discontinued the 105AH 61-21-5-A40-E33 battery and has upgraded it to part number 61-21-5-A40-E29 and that they no longer have any 61-21-5-A40-E33 in-stock. The 61-21-5-A40-E29 is a 92AH battery and I know I can code it as an alternative option but it looks like the dealers are now only offer a 92AH battery even if the car specs for an 105AH battery. I guess I need to go aftermarket but I only see 100AH vs. 105AH available in most auto parts store. Better than 92AH I guess but it would have been ideal to have an exact spec matched battery.
