it is also a way to start a car that has been sitting a long time and has borderline compression.

Unless you must start it right away, why not use a trickle charger? Let it charge for a few days or even a week. Slow charging a dead battery will let the power soak in and minimize sulfation on the battery's plates.

Take the battery out of the car, keep it in a warm (but ventilated) place, and keep it off concrete (Set it on a block of wood).
