I'm going by the numbers I saw on my original battery, and what I see advertised for the replacement.
According to the information in this Exide brochure, their 'Exide Extreme Group 47/H5 has 650 CCA/780 CA, which is exactly what CT advertises for the rebranded premium Eliminator battery I purchased.

FYI...you shouldn't just compare CCA/CA numbers alone. You should also look at and compare RC number as well. Some batteries will boast CCA/CA numbers (because that's just what everyone looks at) but lacks in RC, which means that you won't be able to crank too many times before your battery will die (in the case that your car doesn't turn-over).
