Hi Marco,

I am most definitely comparing old to new, but:

I still find it completely unacceptable that the APC units can *cause*  
a power loss. Again, they stopped supplying power to the things  
plugged into them while they were still getting power from the wall.

The least expensive batteries I could find for the 1kVA APC were about  
$55 apiece before shipping, or about $130 shipped for the pair. It was  
worth $20 to go from beige to black.
