I like Duralast Gold batteries and is what I have in my 2004 MC SS and my 98 K3500 truck. I have not had good luck with O'reilly's Super Start batteries in the K3500 and the Bosch battery that was in the MC only lasted about three years before going bad. I have a Walmart Maxx battery in the 98 K1500 truck with no problems and a Superstart battery in the one 92 Cavalier with no problems.
