They are.... It uses the Banana Block. Then there are molded pieces that fit over the connection on the cell itself. I don't know of anyone with an O2ptima that's experienced corrosion issues in that area. The overall design of the head and it's location all contribute to the lack of issues.

Thanks! Found the same info from the Optima manual. Then it is quite easy to use for example coax connectors on the cell ends if one wants. Also it is even easier to bin corroded connector and just put a new piece of cable in.
