Actually the batteries APC uses in all of their UPS'es are of one of  
three or four standard sealed lead-acid types, and have been all along.

So they'll exchange the batteries for you, you just have to bug 'em,  
because they'd really rather just sell you a new UPS :-)

In our experience using them in the server room and phone closets, the  
UPS usually lives through three or four battery lifetimes, then  
something else in the circuit goes bad and we surplus 'em and get new  
ones.
