| Even when it's ice cold outside. Back in the day when I had auto shop in high school, the rough rule of thumb was to have at least one CCA for each cubic inch of displacement. So a 350 V8 engine would need at least 350 CCA's to start it. Our engines are much smaller (and TT's have low compression on top of that) and don't need much juice to get them started. Even SpecialtyZ's tiny lightweight battery starts the Z without much problem.
