I am about to go to AutoZone to purchase a new battery for my Altima. I'm clueless when it comes to ALOT of stuff about cars. Which would be a good battery to get? To give you a little background.. this is a POS car and I'm intending on trading it in asap (within the next 6 months) so... a 2 year warranty etc really isn't imporant to me. But I would like a good dependable battery. Any reccomendations?
