I'm suggesting that if you goto Walmart the Energizer batteries are less than that.

 

I've always had good luck with a regular GM Delco.

 

I always tell all my customers that have a basic stereo setup to got to interstate batteries and get the best 7 yr battery they have that will fit in your car, you don't need to do any big deep cycle battery but basic batteries are getting shittier and shittier so a good warranty is always a good idea
