Something like this battery?

It costs $170 for 6V ($3400 for 20 = 120V). It has lots of Ah though (250Ah). How many amp hours do you think I should be looking to get? How many years/miles/recharges could I expect for each type of battery? It sure would be nice if some company would produce a 120V battery (it may be huge, but it would be just one part.) I wonder if the Sears 2 year guarantee applies to electric car batteries?
(My current Saturn SC2 looks like that right now with the kayak on the roof, but it doesn't do a good job carrying lumber, chairs, TVs, dirt, rocks, grills, and a few other items.)
