Upon power-on, the unit runs thru a series of beeps and buzzes (normal,
as I recall), then the overload indicator lights up and the unit beeps
continually.

Is the unit toast, or is there a relatively painless fix?

Thanks.

I picked up a new battery last week from Chris Ewert, president of
Uninterruptible Solutions.

In my conversation, I asked him what were the 3 most often seen problems
with the UPS units he repairs and refurbishes (he has seen thousands of APC
and other UPS units)

In order of most seen, failures or other problems:

1. Bad batteries. Lead acid cells are really only good for about 3 years -
but that can vary considerably depending on environment (and batch of
batteries)

2. Inverter circuit failure. Can be repaired - but have to look for other
components that may have also failed OR changed in value (like resistors) --
and then fail a few months later.

3. Battery charger circuit failure
