So I have an old (~10-12 years) GeekSquad 1285VA UPS (same as listed in this thread) and I have replaced the batteries several times, last of which was 3 years ago and now I have instant power loss on less than 75W load when the power cable for the UPS is pulled from the wall so the batteries are due to be replaced again. It did work during a brown out a month or so ago so the unit appears to still be functional. Note: it is possible that the PSU could be at fault due to aging caps not being able to hold a charge long enough for the UPS to kick in as it is 5 years old but it has worked flawlessly so far and I am not about to tear down my PC/PSU to inspect it as it doesn't have modular cables. The batteries are at the end of their expected life span so they should be replaced anyway. Should I just spend $40 and replace the batteries (with these) or should I buy a new unit (min 1000VA but would prefer 1350VA or 1500VA)? If replace unit, what should I buy? I want one that can deal with an active PFC power supply that my PC uses but nothing else fancy is connected. I think a simulated sign wave UPS would be fine but I am not 100% sure. I was looking at a sale on Newegg (and Amazon and BH) for a 1350VA one and 1500VA one. I don't really want to spend $100+ but don't want to throw $40 at a problem and it not last at least 3 years (expected life of new batteries). I can afford to buy a new UPS but would rather not spend the $ unless it would make more sense in the long run. What say you [H]? Throw some knowledge my way.
