We were having trouble with the APC rackmount UPSs getting flaky, so that's why we went elsewhere. The 2U smartups tended to fail by overcharging the batteries causing them to bulge to the extent the batteries could not be removed except by complete disassembly of the UPS. We had 3-4 UPSs taken out of service for this reason. I had a 3U smartups start to pulse the output power and it killed a computer in the process, and I've had the 3u fail to take advantage of a new battery pack.
That said, the APC units work mostly flawlessly within a datacenter with proper cooling. However, out in the field in cold barns, basements, outdoor cabinets or warm closets, they haven't been sufficiently reliable. The tripplites have different charging rates, the 700hf is 6amp, the 750 is 20amp I think, the 1250 perhaps more. This lets me recharge quickly and be ready for another outage. If it's on generator power, it means the batteries can be fully recharged before we run out of gas. On Wed, Jan 21, 2009 at 10:49:15AM -0800, Marlon K.
