Advice Needed on APC Uninterruptable Power Supplies

I have 4 different APC UPSs. They haven't been used in
a long time, probably 3 years, so I wasn't expecting them
to be ready to use. I plugged them in today hoping
that I'd be able to use the APC agent software to
get some idea of the state of the batteries.

To my surprise, all 4 UPSs are acting totally dead,
and don't respond to button pushes or queries from
the monitoring software. Again, I knew the batteries
would be dead but I expected the electronics inside,
when hooked up to wall power, would be able to function.

I was going to decide whether to replace the batteries
but now I'm not sure the UPSs are working at all.
Would you risk buying replacement batteries or would
you just send them to Excess and Salvage?

Thanks for any advice.

Cordially,
