My Dad has a bunch of AGMs' that he scored from a guy.We looked them up, about $325 each!!He put 3 in a Caroche he bought.It ran a suprisingly long time on a charge.I don't know exact use time,but he said that he could run it around for days at the house with out charging.The ones he has are the size of a Group-31 Heavy-Truck battery.I put one in my kids power-wheels,charge it for 3-4 hrs,they ride it for about the same amount of time(And boy does it move and do wheelies!).
