F12 Battery Replacement

I have had trouble with foam gaskets and felt gaskets in the past. Usually had to replace them. Your post #8 shows some of the foam torn off the air box. Maybe good idea to check on availability of replacements just in case. There was no tar or sealant in the far left corner against the windshield seal? Mine looked like there was so didn't risk it. Thanks.

 

To be clear, was there some kind of sealant on the back of the plastic trim piece you removed? If so, would you recommend re-apply sealant in the corner when re-installing? Thanks.

 

Thanks for posting this!

 

Thank you for posting this...very helpful.

I was under the impression that once the battery has been disconnected, the F12 then requires a "reset" (for lack of a better word) of the ECU. Perhaps I am mistaken...quite possible...curious as to your experience?

 

You could also install a LiFePO4 battery. Will save you some 16,5 kg. See https://www.ferrarichat.com/forum/threads/lifepo4-battery-weight-saving-ferrari-ff.641158/

Wrt to a reset. If you just have an auxiliary battery connected to + and - (as if you needed to start the car with a drained battery in the classical way, i.e., no jump-start), you won't loose your settings.

 

Just gonne throw this in there, that if anyone is doing this on an FF, where the procedure looks identical, you can essentially skip this step, and rotate the battery out of and into the slot, without disassembling the wiper-blade cowling.

 

If have the FF workshop manual at my disposition and there is indeed no mentioning of disassembling the wiper-blade cowling when replacing the battery. But an FF is not an F12...

 

The aeroblade on the F12 likely is the reason for the increased difficulty in battery replacement; thus needing the additional disassembly.

 

this great - thank you !
replaced battery today using your guide, worked out really well. lots of pieces and fasteners to attend to, but there was no way to get the battery out without removal of the wiper trim and fan box.

 

thx for write up - i gotta pull mine out tonight

 

FYI, I could not get this window trim out. Mine appeared to be glued to the windshield. You do not need to remove this to get the battery out. If you do it correctly, you can tilt the battery and pull it out without removing this piece or putting strain on anything.

 

I thought the same and replaced it without the glass trim removal. However, the false negative harness needs to come off the top of the battery and tilting will hit that aluminum component directly at the front of the battery tray. There is not 1mm of height to spare and with a +55 lb lead weight your lower back and wrists may also need replacing.

 

lol. yeah i was in pain after that

 

Can not thank you enough for this, saved us all a lot of frustration!!

 

Hi -- first, thanks for all these pics and details. I'm about to replace my battery today and you made the job doable. Question: in the above photo, with the small screwdriver, you are tightening down that little red plastic thing with the two screws. What does that do? Mine was virtually unattached when I removed the battery cover. Thank you. Frank

 

F12lover - Thank you for the time on your excellent procedure! Very helpful and detailed.
Much appreciated.

 

My 4th battery, which was installed at the beginning of year 3 of ownership (yes I did four batteries in 25 months), is now failing after 23 months. Unlike AutoZone, they only have a 12 month warranty.

 

Thanks a lot to the OP. With this I was able to change the battery on my 2015 F12. Took me about 3h and I have not a lot of experience. I had quite some respect to do it myself but the procedure was very well documented, so in the end I was glad to try it.
I used a Moll EFB 82094 as replacement and I hope that one will prevail a bit longer than other batteries.

 

These just attach the "Plus-Distributor-Block" (don't know the correct term) firmly to the battery
