The more recent (less than 20 years old) APC SmartUPS series can be
configured via their serial/USB interface to float charge at less than
the default[1] 2.3v per cell setting, allowing you to chose a less
corrosive 2.25v per cell (13.5v per 12v SLA) setting. I'm not sure, but
I think even that ancient SmartUPS2000 of mine originally had such
provision (I could look at but I could not touch any of the settings for
some undetermined reason).

I know this has been discussed before, but can you please give a link to
a resource for doing this (for those A{C units that support it)?

I have three APC units here, and I'd be interested in doing it. My
batteries last 3-4 years depending on the unit.
