Just put a 110 size in mine, 15mm shorter than the original alfa battery and 80Ah - original was 88Ah.
Looked at many battery selector sites and found several diff variants recommended, none same size and spec as original. Many were not as long and 75-ish Ah (think that included the 096 size).
Trawled forum & again differing advice, but BigGinge has same car and had just fitted a 110 so went with that. Whilst its same length so wont slide around the tray, the 15mm shorter is an issue as the strap isn't adjustable (which I should've checked before buying I guess!). Didn't have any dense foam or anything to pack it out, so twisted it around a few times to shorten it - less strap surface area holding the battery down so will be more pressure, but don't see it as a problem, is tight and battery cover looks robust enough. I'm sure if planned you could find a suitable packer.
It also has more Ah than the 096s I found and 740 cold cranking amps - original was 580A iirc.
