Those are the factory tenders that you get if purchased through parts or a replacement for a warranty concern. The FF battery recommended is a Odyssey battery as they hold a charge much longer and can handle the electronics of that car. The same battery is used in a F12 and California. And yes the battery cost around $685 (parts only) from the dealer the PC1350 on the Odyssey website is $401
For battery, try DieHard Gold EP-49 Model#50749. I think it's mentioned by CrazyMD above. I think it goes for MSRP of $195 or something around there.
Just got initiated- $650 for a crappy OEM battery and $250 for labor from dealer!!! 2014 FF. Just replaced my 5 year old battery on my 575M with my independent $300 battery and labor and he came out to the car for the install. CRAZY!
It’s under warranty and was stuck inside my garage. I prob should have,,,!! . It was easier though to call roadside and have them jump it and flat bed it all the way to dealer. I got a bit nervous with all the warning lights on etc and didn’t want to have any sort of liability by Changing the battery on my own. Wasn’t sure it was just the battery. Ultimately I wanted a brand new battery and all the warning codes cleared and have the car checked out since it’s still under warranty. Love my independent and going forward I may have to reconsider
