Reed,

The last sentence about having to reset is true for some units and not 
true for others.  You can find those that automatically reset.  They are 
a bit more expensive.

"As batteries begin failing, automatic restart back into a protected 
operating mode when power is restored becomes more challenging for the 
UPS to provide.  You can overcome it by ensuring that your battery set 
is frequently tested and replaced well before failure.

What else can you do to ensure that your application will restart 
automatically when power is restored?

Get a UPS with BATTERY INDEPENDENT RESTART ability.  UPS systems that 
include this feature will restart back into a protected UPS-enabled 
operating mode when power is restored, so long as batteries are in 
good-enough shape to provide protection.  If batteries aren't in 
particularly good health when power is restored, a UPS with BATTERY 
INDEPENDENT RESTART will automatically begin passing BYPASS OUTPUT to 
power your connected equipment right-away after power is restored, 
regardless of the condition of the battery set.  While bypass isn't a 
protected operating mode (it won't provide UPS protection), it's better 
than nothing!  This allows your applications to begin operating right away."
