I've got a datatool alarm on mine and it does flatten the battery quite quickly. I've taken to pulling the fuse to the alarm if the bike is going to be left for more than a couple of days, it's still immobilised and can't be started without reconnecting the alarm and pressing the button on the remote, but it stops the battery going flat.
In saying that though, a lack of capacity in the battery does sound like you've got one cell down. I would expect to see over 13v from a freshly charged battery too, so the 12.8 is another clue.
