I am curious whether anyone has found a non-Jag dealer source for the FIAMM AGM 90Ah 850A battery CW93-10655-AA in USA supposedly required for Jags with the start/stop feature.
While I do not need one (yet) I am unable to find a source for this specific battery or a suitable alternative. I expect I could always pay the proverbial arm/leg to a Jag dealer but it is just a battery!

 

Isn't it just a normal AGM battery in the H8 size? Easily available in any auto parts store

 

Perhaps you are correct but whenever I select a battery (H8 included) or a battery manufacturer, no batteries appear to fit the 2020/21 F-Type 3 liter

 

Jaguar replacement batteries are sourced thru Interstate with a Jaguar sticker.

 

I replaced my battery recently (V6S) and I noticed that it looks a lot slimmer but longer than "normal" batteries to fit in the required space, so you might have to go the Jag dealer battery route.

 

I did a lot of research on this a few months ago and worked out that the "best" direct replacement for the OEM battery was the Varta G14. At least for all F-Types up to MY 2020, not sure about MY 2021.
It's correct in every way - Ah, CCA, size, shape and terminals - and in fact it was used by JLR for a while as the OEM battery in place of the Fiamm.
Two problems though - it is ridiculously expensive (try $599 AU) and it may not be available in the US other than as an import from UK/Europe which would mean horrendous shipping cost.

 

160 of our English pounds here ...

 

Yep, us long suffering Aussies get ripped off big time on the cost of "luxury" cars like the F-Type and nearly all replacement parts, and the dealerships are the worst of the bunch.
Fact is in nearly eight years of Jag ownership across three Jags I have never bought a locally available part (other than various fluids and the non-standard battery I bought a couple of months ago) because they are simply unavailable here in Oz other than from the JLR dealership. So I buy from Rock Auto, BritCar etc and eat the shipping costs, which still works out waaaay cheaper than buying from the dealership.

 

You got to choose - low prices or decent weather!

 

Has anyone looked into an AC Delco 49AGMHR battery? According to one of the on-line auto part retailers that is a correct replacement battery. Lists for $165 US.

 

I just measured my FIAMM battery at 13.9in (L) x 6.9in (W) x 7.5in (H).
Actually I measured closer to 13.75 in but figured I was off due to the difficulty of accessing in place.
The other thing I realized was that the OEM FIAMM battery is a European battery size H8.
H8 has the same dimensions as a US BCI Group 49.
The AC-Delco 49 AGM certainly seems to fit the bill, even though supplier web sites state that it does NOT fit the 2021 F-Type.
Once the battery is identified as a group 49 AGM, several options pop up in addition to the Ac Delco battery.
Strange that none of them are stated to be correct for the F-Type!

 

I should have noted that I have a 2015 model. Go to the R....auto site and put in your info to see what pops up.
