Does anybody know the CCA for the 991 70Ah battery is? Is it 760, as that is the only number I see on the battery. Also, it is a AGM battery, correct?

70Ah capacity, 450 CCA according to the 981 Boxster service information guide. I'd be surprised if it were any different on the 991 but YMMV.
They show a part number of 999.611.070 in this book. Definitely AGM.
