my corrado's battery has just died, went to GSF for a replacement, was advised that the corrado actually requires a 61ahr battery (not the 40 that was in it). I was also advised that this type of battery had to be specially made for the corrado to fit into such a small space, but they are now discontinued. Has any one else heard this? Does any one know if i can get a 61ahr battery to fit the corrado?
