Funnily enough I replaced my battery today. I got a deal on a 019 size battery making it cheaper than a like for like replacement. It's quite a bit larger but still fits.
Original - 760cca 70mAh AGM
019 size - 780cca 110mAh Calcium
I coded it in through ista-d and came across some interesting information. The original battery was an AGM type, which the alternator charges at 14.7V. Calcium batteries charged at this voltage can boil. When coded correctly, the car will charge a calcium battery at 14.4V.
I also changed the mAh to from 70 to 110.
