whats a good battery to buy?

the 3 motomaster batteries were crap i bought 1 it went in 2 mths they gave me another 1 on warranty and it went 1 year later, then my buddy gave me his motomaster eliminator battery and it was junk, had car looked at by someone cuz i couldn't find anything and they determined it was a bad line of batteries, bought an optima thinking it was so great at $200 worked fine but when i parked it for winter battery wont stay charged anymore, and i guess i have now been told those batts a good just cant let them sit without use, i need a batt i can let sit for a couple mths and still take a charge
