Cheapest place to buy car batteries?

I go for the RC rating. Reserve Capacity. It's a measure of how long the battery can supply 25 amps at 80F.

It's an indicator of how long the battery can keep your car running if your alternator fails you on a trip.

Is this for your new car? It seems like just a year or so back that you picked up your new digs.
