Alternative start battery

[gus]

Lin,

The only thing I pay attention to is CCA since this measure has been around much longer and gives me a better reference.

CA is relatively new, and, in my opinion, is only used because it is a larger number and most buyers don't have a clue. The mfgrs know this. Keep the customer confused!

Reserve capacity is good if you have starting problems but most DDs start right up on the first turn if fuel supply is good. Guys in the northern frozen wastelands might consider this more important, but our climate is mild!

To me, Ah only applies to deep cycle house batteries. For those, CCA and CA don't mean much.
