Looking at getting a new battery for my 1989 Jaguar XJS v12 Marelli.

Australia so using Aussie brands/websites

Is the below good? Or better to get a higher cca ?

Been a loooong time since I left the Indudtry.

CCA is the Grunt to start the thing, so anything over 450cca is bonus. UNLESS you have a hard to start V12, and have not sorted that yet. A V12 should fire up at NO more than 2 rotations of the engine. If not, fix it. I know I am a PITA, its allowed at my age, and way too many Jags.

Reserve Amp is less concernig, UNLESS it has aftermarket gadgets consumong power after shitdown.

Memory, ha, I used an Exide (IBD in the day) N54 in all the S2 and XJS. That tray is :just: big enough.

A Battery Monder is a good thing, all my fleet have one attached when sitting at home, like playing Tesla, oops, bad luck.
