Sure, but I've never had one of those ATSes fail. For a sample size of ~15 over a decade. Where I've pretty much had every APC BackUPS and SmartUPS (mostly 1500RM 2U, some 3000 3(?)U, some 2200 floor units) drop power at some point. That includes being very liberal with battery replacement, the last one was <3 months with a new battery. I would say that they seem to be reliable within 3 years, It's outside of that 3 years that I've had problems.
