I've got the immatation batteries from NAPA. Orbital is the name I think. The colors are different - blue is deep cycle , Red is combination , and gold is starting. I have the red and blue in mine.
All these batteries are made in Spain,,,,wonder if both brands are from the same manufacturer.

The only problem I've heard of 'round here is - if you drain it all the way it can damage it. If almost all the way you have to charge them real slow or it damages them.
Comments??????
