Never met a properly designed plug-in UPS. Current lead acid battery technology says the UPS battery should last up to 20 years. Even a car battery lasts up to 10 years when sitting outside and used almost daily. Why then do plug-in UPS batteries rarely last more than 3 years.
Furthermore, why do those UPSes use unique batteries that cost almost as much to replace the battery as it does to replace the entire UPS?
That does not meet the criteria for reliable. It does meet the criteria for cheap. But then we traditionally buy on price; not value. It is reasonable for a plug-in UPS to last up to 20 years and more than 10 years. A UPS does nothing spectaculor, nothing exotic, nothing stressful, and nothing that could not be done 20 years ago. $300 is too much to spend on a battery that only lasts 3 years.
Remember when automakers assumed you would replace shock absorbers every two years. Then the Japanese appears with cars that never required shock absorber replacement.
