This is my second APC Black-UPS. My first one is still going after four years, and not one problem. This UPS has every thing you need for a computer station. I always get a great price from APC.COM.
The life of my old battery was about 3.5 years, normal for this application. When I installed the new battery, I still heard the ear-shattering squeal. Turned out, the black connector came loose as I stuffed the battery back into the UPS. Normally these type connectors are somewhat tight; these are not.
