I am looking for mobility, so I was looking more towards using 2 of the 7.2 backup batteries from past years, but I cant find the amp hour rating them. Does anyone have any idea what it might be?

After looking around I think I will do a LM317T circuit on the batteries, but I would hate to buy all of the stuff and then find that it lasts for 10 minutes or something.
