Clarke-
After researching more,
would be the maker of the floor scrubber
to get parts for these even batteries, you
need part numbers.
lol
Luckly I have the battery numbers
And to buy these bat's new, wow!
$234.00 to $260.00 each, (maybe each after seeing that price I didn't
care to look much more, LOL)
Anyways,
These are .... 250 AH
And yes I got the other two today, 
Total of six now!
Maybe I'll be able to wire up a bank at
30V DC to be able to test
the BEST inverter, (it needs 28-38 VDC)
