Wow, What a find. Great for the FX-FJ brigade. All you need is to find someone who can recondition it. Do you know if it is the same dimensions as an oringinal 12 Volt battery. It looks to be taller and narrower than a twelve volt. Maybe you can get the extra plates put in to make it a twelve volt batery if it is the same dimensions.
