new battery

Go with the AutoZone battery, Made by Johnson control one of the leading Manufactors in batterys... Second I would Do a voltage drop test on your battery, Post to terminal, Ground to Block, Ground to body, and power terminal to Starter, Excessive resistance in any of these area will cause problems, Third i would do a Amprage draw test with a multimeter should not have more than .050 milli amps with the key off doors closed with nothing powered up..Last check for charging system overcharge, could cause early batterie Death!!!!
