Successfully revived two Orbital batteries for backup purposes. 
 
Battery specs. are here:

The plan is to tie them together as a backup supply for the entire shack in conjunction with an inverter (anyone got one cheap to trade or sell?).  
Total cash outlay so far, $18.00 ("core value" for the two batteries).  They were new, but on the shelf at work since '05.  
They seem to be good as new after charging with my Samlex APS 1215 (shown below, 15A cont., 20A surge) which will be devoted to keeping them charged.
