Keep in mind that pretty much all of them that don't have multiple battery/control modules and auto-switching (like the big APC Symmetra's) will have their own failure modes 3 or 4 years out if you just plug them in and forget them. That is, they will cause downtime even if you don't have a power failure.
*shrug* You run the self-test every so often, or have apcupsd do it. In any case, when the "replace battery" light *first* goes on, order new ones, and replace 'em when they come in.
I think we've had many where the "replace battery" light never came on until after they had dropped power.
