Something to check from a safety standpoint when extending to alternate 
batteries is that some ups's battery leads are floating  near ac line 
voltage. At least my little apc that I have has warnings on it to that 
effect. Just be careful when you do it. There may be more than 12 volts 
lurking on the b+ to earth ground.
