The SmartUPS are... but then, overwhelmingly, mine are rackmount. I have mentioned here, before, though, that at least with the SmartUPS, you can easily, and far less expensively, buy replacement batteries, but they *MUST* be HR (high rate) batteries; anything else, and the SmartUPS don't believe they've been replaced correctly.
quality VRLA (SLA, AGM) batteries are capable of delivering massive current loads, I've not had any problems using these on good UPSs. At home, i've got an /ancient/ SmartUPS2000 (2KVA) tower unit that I repopulated with Panasonic 12V 20AH 'motorcycle' batteries. its been running great now for nearly 10 years, and STILL can keep my entire home computer load going for 4+ hours in a failure. These batteries are WAY past the 'normal' end of life, but are still doing very strong. I even put a safety light on them, a floor lamp with a 7W LED bulb bounced off the ceiling, thats left always-on, as this room is quite dark.
