In the just-released April Acura ServiceNews (linked in the stickied ServiceNews thread at the top of the forum), a new matrix of various battery CCAs was released. The purpose was to help parts staff properly identify the correct battery for each model. Our model happens to use a 550 CCA battery. Just passing it on in case you weren't aware.

 

Good info Bob, that comes in around 700 or so CA which I would think to be the minimum for this car with issues such as telescoping steering wheel,etc.
