I have several Belkin Model F6C120-UNV UPS units in need of repair.
These are 1200VA UPS units designed for 120VAC type operation. Can
anyone recommend where schematics for these may be obtained?

If it turns out that the repair needed is simply to replace the sealed
lead acid batteries in these units is it generally considered cost
effective to do so or is one better off just getting a new unit.
