Honestly I've never done this, and neither has anyone else that I know of. That said it can't hurt to be extra cautious.

Yes, definitely, unless you want to frizazzle one of your ecu's...

How do you wait for it to go to sleep with the trunk open? My trunk light & headlights seem to stay on with the trunk open?
Bought a Duralast battery at Autozone. H8-AGM. 900 CCA, 95 AH. It was $199 but got $20 off "managers discount" (ask & ur shall receive).
It's bigger than the H6-BMW flooded acid battery it replaced (which was 640 & 80 AH). It fit and filled the entire space. Followed the directions, installed it easy.
Coded using Carly, connect, read battery info, choices are 80, 90 or 105... hmmm.... Carly says choose the next below the AH rating. Select 90, Register & done.
I didn't bother waiting until the car went to sleep. It worked & nothing terrible happened so that's good.
The only strange thing is that Carly didn't charge me anything to Register the battery. I'm one of the legacy purchasers who got in on the one-time charge for the app vs. now with the annual fee. But I thought registering the battery was still an added charge but it let me do it without a fee so I guess that's good.
Hopefully that stops my S-L-O-W crank issue. We'll see tomorrow.
Thanks
Matticus91 great DIY write up.
