honestly draining the capacity is risky business on a very cold day. you only get a few tries to start the car.

a lot of folks crank too short and kill the starter and try a re-attempt while it is better to just keep cranking it for up to 10sec or so in one shot. (i suppose it will 'warm up' the battery too while doing so)

not sure how long the cranking duration is on the Z since it's a push-start..and i dont drive the z in the winter.
