I have a Cyberpower UPS that's been working great for several years. I noticed yesterday that when I had a power glitch, it died immediately. I took it out of line and put it on my bench with no AC input. Power up and it says it has plenty of capacity, (no AC input) but when I add a small load to it, it dies completely. I took the batteries out and they show 12.72 and 13.03 volts respectively. I have no way to load test the batteries properly.
Any ideas? Allen R. Brier N5XZ 1515 Windloch Lane Richmond, TX 77406 713-705-4801
