Instead of taking it out you would be better off putting a battery maintainer/conditioner on it.Just unhook it when get ready to drive. The cold does take away some cranking amps as to warmer weather. The maintainer/conditioner may help the battery last a little longer if is getting weak.The worst thing you can do for a battery is let is sit around and let the voltage go down if nothing is keeping it up. The other thing to consider is your oil. If you have a heavy weight oil it will naturally crank slower. Most manuals in those days would state to use a lighter weight oil for colder temps. This is also better on the engine. Gets the oil flowing in the engine better. The newer vehicles all use 5w30 these days so not much of an issue like back then.
