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!
