T-W, a car battery will typically draw +/-30 amps when charging. A battery pack is rated somewhere around 300 amps or more. The dead battery would have minimal effect on starting in warm weather. Cold weather may be a different story. That’s why you need to charge an emergency battery pack every couple of months if you never use it.
