Another decent battery is the Duralast Gold. They come with a 3 year free replacement warranty and 8 year limited warranty. They are made by the same company as Optima batteries (Johnson Controls Battery Group Inc.). I'm on my second one, killed first after draining it beyond 0% with dead alternator they gave me the free replacement and warrantied the new battery. They are great truck starts every time even at times when I've majorly depleted the battery(like when the alternator died truck started without hesitation at 0%).
