I have 2 MGE UPS systems Pulsar 14+, that have been sitting around
unused for a year. (Long story about life getting in the way...)
When last used, they lit up and took a charge fine. I pulled them
out today, now that I finally cleaned out and rearranged my computer
work area, and wanted to put them back in service. Nada- no lights,
no noise, no nothing. I expected the

What bob siaid. But while I'm here, every such thing I know should
work somewwhat or maybe well without batteries if you have AC. I
don't think this will help, but disconnect the batteries altogether
and see if all but one light lights. If not, start iwth the basics,
the cord, the switch, looking for damage on the circuit board.

Maybe check the lights too. Maybe they share a common ground that is
bad.

And check the output. Maybe you do have 110 coming out of it.

batteries to be flat, but the light for the incoming wall power
doesn't even come on.

Anybody out there (Jeff W.?) have any idea what is going on? These
are from a garage sale, so no docs. I looked on vendor web page, but
didn't find anything about dying in storage. Did the batteries (gel
packs, like a fire escape light?) crap out completely? They were
never dropped, never frozen, etc. Any point in trying to repair or
replace the battery packs? Or are new ones so cheap it isn't worth
the bother? And just how do I get rid of these, if they are junk?

Just an add, some UPSs completely shut done with bad or no batteries.
The
one right in front of me does that. I don't remember if the power
lights worked
or not with bad batteries, but I know the computer did not get any power.

And to add to the above, if the batteries were sitting around for a year
w/o charge, (and were old to begin with), they are probably completely
dead. If they are 12 volts, you could take your car battery out and
temporarily hook it up to the UPS to see if it would work. Or string
together a bunch of flashlight batteries, preferably rechargeable.
And to add to the add, many UPSs use 2
12 volt batteries in series, so
you might need 24 volts.
