Battery discharging, part 2

So, it appears the discharge is slowing down.  I'm going to take the battery down to the bike to try to start it up.  I'm not sure I should be heading out there today.  There was a slot of snow dumped onto our streets a couple of days ago.  Most of it should have been cleared but there might still be some lying around, still dangerous for a motorcycle.

Update:  I haven't tried connecting the battery back to the motorcycle yet but I suspect it's not going to work.  According to the following webpage, this battery is no good:

It appears that on day 1 (when I brought the battery into my apartment), it was down to 70% capacity already.  It nosedived to 12.3V then slowing down to 12.2V (or 50% capacity) over a few days.  With only 12.16V today, it's essentially dead.
