Just one of many hitts from a search on "li-ion battery care":

Most UPS "failures" are batteries that need replacing.  I've replaced 
them in both my small UPSes from Internet sites.  Just make sure you 
dispose of the old one properly (the county here has a hazardous waste 
disposal facility where I can drop them off).

They're all alike as far as I'm concerned - choose one that has the 
capacity/features you need and plug it in.

Actually, according to the link above, you should use only a partial 
discharge rather than a full one.  I really don't worry about what I 
discharge to - it's either when I plug it back in at whatever charge 
it's gotten to or maybe 10% if I've been pushing it.  I suspect it's 
more that you just take it off the charger and use it for an hour or so 
before plugging it back in.

Yeah, that would be tempting fate...  ;)

> What did you mean by "manual discharge"?

My "manual discharge" is simply using the computer or leaving it on 
without letting it sleep/hibernate.
