I paid 103 for mine but I had the hookup... its goes in my 68 when I go racing and off road in my truck when I go mudding, its been dropped, fell into my fan once, then into the timing chain cover... never has let me down... lets me listen to my system for long amounts of time while the cars off. I will not buy another cheaper battery... you caa get one with a 1 year warranty for 40 bucks or an optima with the 3 year...
