The stock AC Delco battery is ~42 pounds, the ZZP race battery is 11.1 pounds. It is powerful enough to start your car no problem. Weight savings will lower your 1/4 mile ETs and give much better road racing performance. It will provide 12 amps for 30 minutes so it can be used as the car's only battery. We have tested to zero degrees F and had no starting issues. However this is a race mod, it should be noted that the reserve capacity is a lot less than a stock battery, so it should not be used for extended periods without the car running and it is not recommended to be used as the main battery under 40° F.
