my car wont fit a yellow top under the hood the bat box isnt big enough, so i bought an exide orbital battery for under the hood. i wanted to install a 2nd battery so i bought a yellow top for the back, then my local shop told me that you have to have the same battery in the front as you have in the back or they will "fight" each other. is this true? i returned the yellow top and bought another orbital but im still not getting enough power. is that true? and how do i contact iraggi?
