To start this video is based on your BMW being compatible with an app called MHD. You can check the compatibility here:
https://mhdtuning.com/mhd-flasher/
This app allows you to tune your turbo BMW but also offers support to register a new battery with just a click.
The process would be similar for pretty much any BMW from the last 12 years. I specifically am working on my 2008 335i E90 with the N54 engine.
If you ensure that you’re replacing your battery with a battery of the same specifications you can save a lot of time. If it’s AGM you’d put in an AGM, if it’s lead acid you’d put in a lead acid. If it’s rated at 80 amp hours you’d put in an 80 amp hour battery etc.
I understand this video may not help everyone so I still have my original video where I got into a lot of detail here:
I also have an even older video where I make the switch from AGM to lead acid here:
If you do not have a K + D Can cable you can get one here (affiliate):

Dissect the whole car apart to install the battery!
Oh yes it’s so much easier when you’ve got all those fucking accessories to work with
Will anything bad happen if i just unplug the negative terminal? Only did it because i just detailed my engine. Will let it sit over night.
Vehicular diy. So to be clear can you do this by plugging in the K+DCAN to a tablet instead of WiFi ? And do you pay for the MHD app?
Will my oem battery specs match up and be in spec with a non bmw battery?! Hell please
Alrighty, so I have the mhd and battery’s is the oem bmw white battery 2011 335i. Where can I find one that is the same?!
AGM batteries are lead acid.
Good.
Grief.
Higher Ah or cranking amps rating will not negatively impact anything (other than be more expensive).
MHD now rquires a license to register the battery.
0:32 AGM (absorbent glass mat) batteries are lead-acid batteries. The term "conventional flooded" will differentiate this from AGM. Both designs are lead-acid, as is gel cell. They all rely on the same reaction between lead and sulfuric acid.
