I've been told DEKA batteries are worth considering. A couple of friends have told me their Optima batteries didn't work out as they had hoped. Those are made in Mexico these days...maybe they always have been. Once upon a time I was told they were made in the USA but not today. I bought a 12v battery at Wal-Mart that cost me about $85 and it is working fine (EverStart or something like that), but honestly speaking I don't expect miracles with any of today's batteries so I'm usually not disappointed.
Good luck.
