Help me fix my batteries?

[Gee]

I hear coca cola will clean corrosion of battery terminials on cars. If you try it you should unsolder one of the wires from the dean plug and then soak the dean in a bit of cola. The taps might be a bit of a problem. Maybe try and use a stiff brush with some cola on it to clean them. Best thing would be to cut the wires back and install new deans.
