flooded v. sealed batteries [RE-wrenches]

[Darryl Thayer]

Matt 
Are your batteries lead-antinmony or Lead-calcium? 
How many AH is a typical size?  How much do they
weight.  

After lugging around heavy batteries, how about
getting single cells and assemble on site? About all I
can handle is 800 AH cells.
