No, a bad cable just won't be able to deliver as much current which is
critical when cranking.   If you leave the car until it's reached a
final cold temperature, say 8 hours and it starts OK, but won't crank
about the same after sitting for say 24 hours or 48 hours at the same
temp, that suggests you have a small load that is not turning off and
draining the battery.

You can disconnect one of the battery leads and insert an amp meter.
With everything off, the current should only be 10ma or so, which
would be the clock, etc.   If it's substantially more, something is
drawing current and you need to track it down.
