My alarm, combined with leaving the ignition/headlight on whilst modding - IDIOT! - did exactly the same thing. In the end I went for a gel version of the YTX9-BS, altought a fair few other people on here have gone for the larger YTX12-BS (not the same as the YTX12A - beware!).
If you can get the seat to fit properly (the 12 is an inch or so taller than the 9, so a few have had problems), then suggest you go for the 12 as the capacity is nearly half as much again. Not sure if the toolkit will fit back in though.
I have way too many electrical toys on mine, so am chained to the Optimate - so much so I take it with me when going away for more than a few days.

If/when the current 9 dies, I will definitely try to fit a 12.
