Greg,
These are plain 6-volt sealed lead-acid (SLA) batteries, with an obvious 5AH 
rating.  Just get on the web and find 6V/5AH SLA batteries with the same 
dimensions and terminals, and you're all set.
Some battery vendors are:

Google for SLA Batteries

I went to a bookstore and asked the saleswoman, "Where's the
self-help section?" She said if she told me, it would defeat the
purpose.
