With standard motorcycle (or car) batteries, you're looking at a
battery that can deliver a large amount of current for fairly short
periods of time (just long enough to get the vehicle started). A
motorcycle battery will very seldom (if ever) be completely
discharged. With UPS batteries (or batteries for things like electric
golf carts), the battery is designed to be more-or-less completely
discharged on a more-or-less regular basis. I gather the key
difference is that "deep discharge batteries" need to have
tougher/thicker lead plates than "starter batteries".

Well, Above-All Electronics near Bloor and Bathurst carries some small
sealed lead acid batteries, some of which could work with some UPS
(note, anyone who remembers Above-All from say 5+ years ago should
know that they have moved, a handfull of doors west...).
