Probably true. Particularly if the batteries were charged when put into 
storage and kept relatively cool.

Generally, it is recommended to charge lead-acid batteries every 3 to 6 
months. More on storage here:

Sounds fine. I wouldn't recommend doing a full discharge runtime test. 
(Apparently some people do that on a regular basis and APC has taken to 
printing warnings in their literature not to do this, as it shortens the 
battery life considerably.)
