Question about Belkin (F6C800-UNV-PL) UPS System
Dc power from batteries is switched (inverted) by semi conductors. this involves switching on and off the dc supply buss to create an alternating voltage. if the devices are blown then as soon as the unit is connected to dc the dc shorts outs and blows the dc fuse, this could be your problem. unless you can get a good power electronics tech to fix this for a reasonable price you should recycle this and buy a new one. in some ups systems the dc from the batteries go via a dc up converter which increases the dc voltage to a level the inverter will run at. all this circuitry is difficult to work on and almost all of it is controlled by logic circuits and software.
one last word
batteries are always live and are very dangerous, remove all metal objects watches,rings etc before handling, wear eye protection and take account of all instructions supplied .
with batteries if in doubt the don't work with them.
