Go with Deka Marine Batteries, they are the best in the business and made in the USA, not China, like the other manufactures of Batteries. Sears Die Hard Batteries are sold by Johnson Controls, who buy all their Batteries from China, as do most battery companies.

I'm an Optima believer. It's been awhile but I think their warranty is 3yr free replacement with another 2yr prorated... but double check.

I believe East Penn makes Deka batteries. West Marine carries batteries manufactured by East Penn.
