I would find out the following, how do you know when the back-up battery is
dead? I've seen the following on an APC system (can't tell you whether
others are the same)...
- Back-up battery silently died
- The way to "check" the battery is with a scheduled "battery test"
- A "battery test" switches to battery power and checks all is well.
- The battery is dead so as soon as the "check" happens, everything keels
over!
Also, some APCs require you power off to replace a dead battery. OK if you
don't mind but useless for a high-availability system.
Also, APCs have a single serial connection for "Power-Chute" which won't
shut down more than a single PC. The add-on "more serials ports" board is
very expensive. You might find alternatives that can support more than a
single PC shutdown.
