My old UPS (APC Back-UPS ES 725VA) has died. It might just need a new battery, but I'm in doubt. A few months ago I started getting a constant alarm (which I disabled in powerchute), and after the last outage a few days ago it now claims the battery isn't even connected.
I'm looking for a new UPS. The models I've been looking at are in the 1200-1500VA range. My old unit was 725VA but I think it's a bit small now. The 1200-1500VA range might be more than I need but the pricing seems decent on those.
For about $200, I can get an APC Back-UPS RS 1500VA.

Besides newegg, I can get similar models locally.
For the same price (shipped), I can get this:

That's a used SU1400NET. They say "refurbished" but let's be skeptical and assume it's just an old UPS with a new battery. My understanding is that this is an old model, but I don't know how old.
Is there anything wrong with buying a used SmartUPS? Assuming a good battery, do they pretty much run forever? Or do other parts tend to wear out?
I know that in good condition, a SmartUPS is more desirable. I'm not too worried about sinewave vs step-wave, but presumably the SmartUPS also has generally better build quality.
But I'm wondering if there's an aging issue to consider. Should I expect the new Back-UPS RS to last longer than an old and used SmartUPS?
