Thanks Brad!  Let me know if I can ever return the favor.  Industrial 
electronics is my profession.

The High Voltage Warning stickers on these units were telling the truth.  
I have never measured 245 volts from a battery before.  Most of the
batteries are still good, which is suprising.  They are of the 1994
vintage and lead acid batteries usually provide 5 years of good service.  
They appeared to have lived a good life.  The batteries that went bad,
looked like 245 volts went through them and did their worst.  I'm guessing
the batteries with holes burned from one side through the other are bad.  
Now I just need to save up for 24 marine batteries and insualted cases.

Hopefully, I should get these wired into my bomb shelter by the weekend.  
I plan on making an Extreme-UPS-HOWTO with pictures about this...
