Ever wonder whats in a replica battery?
Now that is 'classic'!
I thought they were just slip covers for regular Die-Hards......
The "Deluxe" 20H Group A-body battery that was stock was a whopping 38 Amp/Hours...about 200 CCA. Those 2 UPS batteries in parallel are probably close. I got a jump starter that takes 1 UPS battery, Duty cycle of about 5% crank for 10 seconds, let it rest for 3 minutes.
