I would also suggest checking with your local distributors technical expert on the Optima battery. Here in VA it is Inerstate Battery and they were very knowledgeable, asked me several questions about the useage for the batteries. Then made a suggestion, for race care application, one red top ( battery attached to charging system) and one yellow top ( batttery charged periodically). I felt good talking to a real person, they also provided me with knowledge on how Optimas need to be cared for, very important.
