Eaton is the only UPS manufacturer that seems to be trying. All others (I’ve worked with most all of them) do simple float charging of their batteries and scheduled “tests” which just involve blindly switching load over to battery for a few seconds.

Eaton’s ABM* at least doesn’t do that, so your UPS doesn’t drop the load during tests when the batteries are unhealthy. They also make plausible claims that it substantially improves battery lifetimes (which eventually becomes a larger expense than UPS purchase price). But pay attention as not all Eaton UPS units have ABM.
