I started with a 11 lb Braille battery, which worked fine for starting the car year-round. But I was also using it to power two outboard amps for the cars stereo and it did not quite have the current when the subwoofer was really booming. I called up the folks at Braille and told them about it and they said no problem, send the battery back and we will send you their 15 lb battery for just the difference in price of the batteries. I was very impressed by their customer service.
The 15 lb Braille works fine both starting the car and driving the outboard amps. The coldest starts I have had have been in the low 20's and it pops right over. I would think if you got their 17 lb battery, which they rate for winter use, you would do fine and save a few lbs. If you are interested in saving weight for your car, it is one of the very cheapest ways to go.
