Battery Upgrades ?

Oh wow haven't heard about this option, what's the fitment like ? Any modifications.
No modifications. It just drops in. The hardest part was coding it. Protool doesn’t have a setting for 50Ah AGM and recommenced I set it to the next highest which was 60Ah AGM.
A few weeks later I had a friend with an expensive tool recode it for me.

Yeah 800 is silly for a a battery but they say it will last 8 years, so maybe double the normal battery life, 2 400 braile batteries with a tray adds up to that. Idk just trying to justify me blowing more money.
How much did the i8 battery cost you kitty?

Every once and a while I see a fragmented, bread crumb conversation on batteries. Often it is on brands, then we reconcile branding down to the few actual manufacturers, AGM discussion, size alternatives, battery maintenance/conditioning, pricing, warranty, etc. Deka (East Penn Manufacturing), Delphi, Exide, Johnson Controls (Optima is a subsidiary btw). At least in the USA.
It would be nice to see an organized document that actually cataloged some choices, and framed basic stuff, like who is manufacture of the brand, capacity, fitment (and mods).
My last go around, after the usual 2 hours of research - I figured out who made the Advanced Auto Parts AGM battery (their high end offering), then I scraped a bunch of coupon code deals together, along with a special they were running on their batteries, considered the warranty (which seem pretty good). In my case it was an Autocraft Platinum AGM H6 760CCA for the wife's diesel MB, 3 year replacement warranty, and came to $140 which is dirt cheap. The Autocraft Platinum AGM is made by Johnson Controls (JCI).
Generally the AGM batteries seem to last longer by my anecdotal experience. The Z4 sees infrequent use so I keep that on the battery conditioner.
As for $500-2,000 batteries, to save a bit of ass-end weight, that's pretty much a poor trade-off by any set of metrics I can imagine.

It is a horrible way to spend your money. Literally one of the worst bang for your bucks IMO.
Put two of these in the car ~8lbs...
or one of these ~4.xlbs...
Just don't expect Li to work well when it's <40f outside... They will turn the car over when it's warm out though. Not good for a daily. Great for an enthusiast... Not sure why you would spend $1000 on a "brand name" product that is grossly over-stating their batteries CCA and AH ratings... Li battery's are not tested and advertised the same way as a traditional battery so those numbers are pure BS. A "30 AH" Li battery is really like 8-9AH. 1000CCA Li battery is really like 300CCA. You need about 360cca to turn our engine over, from my experience. The PC925 battery is rated at 330CCA but it has a burst rating of much higher so it actually does turn the car over. I had a generic 20lb agm battery that stated it was rated for 400cca, tested at 360cca, and did NOT turn the car over whereas the PC925 dis.

Paid around $320 from a SoCal dealer. No issues to report to date. I just made sure to top off the charge using my Ctek and everything has been great since.
No issues with long cranking due to me running on E85 either.
Long cranking actually was due to failed injectors. This battery fires it right up with fresh index 12s.
I’ve been beating on the battery and no errors. Heated seats, radio, radar detector, convertible top use. It’s a good upgrade.
