When mine was brand new, it'd wouldn't start the car after about 7 days. The only load on the battery while the car was parked was the alarm. After about 2 years, it was only 3-4 days before it would need a jump start. You'll want to make sure your cold start is spot on too, even when it was brand new and fully charged, it would only crank the motor (~9.2:1 static cr) for maybe 10-12 seconds before it needed a boost.How is the PC680 battery going? How does it like starting when youve left the car parked up for a couple of weeks?
I use this Full River dry cell in the race car
I had to post this up lol
Try 2 batteries
