Look at the date codes and make sure that they are not way old. They would have been communication batteries or some kinda UPS battery. The amount of power that a moped puts out probably wouldn't hurt the batteries and they would keep the lights shining when you were at a stop light. The problem would be in the voltage of the charge. The gel cell batteries aren't designed to take as high a voltage as the wet cell batteries. If you have the numbers off of the old battery, you might be able to get one cheap thru JC Whitney. They sell the 6 volt battery for my Fa50 for something like $5.00 plus a little to ship but the small motorcycle batteries don't cost much to ship anyway.
