Thanks for sharing the link for the sib. Mine is a 2007 X5 4.8i. Just bought a 105ah agm battery from the dealer, and registered and coded myself using ista d/ista p.
In this sib, it says that E70/E71 models before 09/2010 although can fit a 105ah, we decided not to take this risk, because vehicle integrity could be compromised in an accident. So what are they saying exactly? But after I programmed and encoded a larger size using ista p, I went back to check if all was registered correctly in ista d- it said the current battery registered is 80 ah? I don’t get it. Or does the dme need some time to fully register the new battery rating correctly?
Sure the trey was too small, but I can just move the holding bracket few inches to the right. There’s a drain hole (larger than 10mm bolt), maybe 12 mm will fit there just fine, plus some drilling of the bracket would be required.
I guess my question is, has anyone here replaced their factory 92ah agm battery to an oem 105ah on their E70 X5s successfully and has been a happy camper?
Thanks!

Watching this and your use of a tripod to prop open the cargo floor door reminded me how much I appreciated my 2007 E70 having a gas strut for this and how disappointed/annoyed I was to see BMW cheap out in later model years.

The kit is available for the later E70s. Holes are there and everything. It does make them seem pretty cheap.

I was searching for some kind of strap/clip like what exists on the E53 lol. Now I know what my next upgrade is going to be!

Yep, bought it for ours. Was ~$30 if memory serves. Hilarious BMW didn't include it in all E70s. Bean counters...

You can get a much cheaper equivalent strut on Amazon to bring total cost down to about half that.

Time to replace my battery again. Last time I used an Odyssey PC1350 49 H8. It was a Dec 2017.production, installed in June or so 2018. Lasted a little longer than the original BMW 8/2011 battery. Can't really complain for $320. Now Odyssey has a ODP-AGM49 H8 L5 and it's $430 at Napa. I used Carly to register it before as a 105Ah battery even though it was C/20 95Ah. That's what Odyssey recommended at the time.

Bonus! Napa had a 20% code so it was only $346! I also bought the Odyssey/Ctek OBC-25A charger to supplement the legacy OBC-20A I've had for years. I'll charge the new one for a week or few days to ensure it's topped off prior to installation.

Only until recently did I come to learn how much I don't know about today's type batteries. And there charging. So much has changed and to the favor of the consumer.
But please what ever you do...install the proper fit for the car!
Just made a run to the bone yard recently...there was a x3 07 there where the trunk was
burnt out only due to a small battery from Walmart.

(Walmart batteries are some of the best on the market)

I Couldn't make out the amps due to the char. But it was small say maybe H6?
Apply the proper fit/size.
