Actually, I did not write that...
but the website that was referenced, specifically cautions AGAINST using the amp
hour rating because different battery manufactures use different hour increments. I
battery that has it's amp hour rating for a period of one hour would have a higher
rating than one who used a 3-hour time period.

The web site cautioned against using CCA and Amp hour ratings and to instead look
at the Reserve and Cycle life to judge the quality of the battery.

I'd be interested to know if you think otherwise.
