Johnson Controls makes the Everstart batteries sold at Walmart. Ever since they started making them, I have used them in all my vehicles.

Diehards used to be manufactured by Johnson Controls, back when they used to last --remember? I was employed at Sears Auto Center when they switched manufacturers. The quality went way down when Exide started making them, and Sears lost alot of loyal Diehard battery customers. Exide also makes Autozone's batteries.

IMO the Everstart batteries are among the best values on the market today as far as automotive batteries goes.
