Battery Question

[warment]

What is the total combined CCA rating of two stock batteries in a 1973 911 T? I am getting ready to convert to a single battery and install it into the "smugglers box".

I am interested in a G26EP/PC925 Hawker/Odyssey battery. I know quite a few of you guys use a dyna-batt and say they work just fine, but I am interested in going up one size from a dyna-batt for good measure. The battery is rated at 470 CCA, 590 CA, 700 HCA, 925 PCA (9 sec), 870 PCA (10 sec), and 765 PCA (20 sec). This seems more than adequate and appears to be much more powerful that the stock 2 battery setup.

Thanks for any help.
