First, appliances should be OS-independent; they should talk a "common
language", that doesn't care if it's on Windows, Linux, Unix, etc.

Secondly--as you'll continue to see me state in this post--the problem
is that everyone wants "cheapest possible".  That means they go for
things like lead acid--cheap, mature--and LCD on any drivers or
associated software.

Essentially, batteries are batteries.  The vendors aren't going to go to
the immediate cost of custom "smart" batteris and support costs of a
specialized battery.

To meet that criterion, you essentially need to find a local battery
supplier who has either original vendor replacement batteries, or
acceptable aftermarket units designed for your UPS.  Given the economy
and the decline of bricks'n'sticks stores, good luck.

Again--the end users are demanding cheap.  They get cheap.

Cheap.  See above.

The most depressing part of all of this is that companies producing
professional-quality units aren't rewarded, so they either die or turn
out low-end junk...as we're seeing.
