The Optima Red Top installed 4/2014 gave up today - it was $152 delivered from Amazon in March 2014. Measured at 204 CCA. I recently had an alternator fail - it's been two weeks since the alternator was replaced.

I replaced the battery w this:

5 year warranty. I understand this is a rebranded Northstar and similar to Odyssey. When tested on counter it was putting out 800 CCA.

I paid $239 (w 10% coupon from the Montrose Mafia), came to $258.17 out the door.
