I have an APC Back-UPS ES 750 to which I have plugged in my PVR (a not
particularly high-powered computer, and with only one HD). It is not

the power goes off, even for just a second or two, the UPS indicates
that it is overloaded (no indicator lights, and continuous sound).

Is it worth replacing the battery just in case, or is this thing ready
for the recyclers?

Whether it's "worth it" or not would depend on how much you're willing
to spend on the battery. Whether or not that will cure things, shrug
no way for me to say. The battery is the most likely thing to be
failing, but without a whole lot more information than you're likely
going to be able to give online, there's no way to be certain that's
truly the problem.

If you can get your hands on a battery cheap, it's worth trying. If
not...


Ditch the Back-UPS and get a Smart-UPS off eBay--they're much easier on
batteries. I collect the rebadged ones (IBM 750T) and stick Powersonic
batteries in them. I have four running at the moment.
