Batteries in storage will discharge no matter the temperature. In cold storage the electrolyte in the battery can freeze (will in these current Alberta temperatures). Worse, if the battery is left in the car and freezes and splits the case it will cause serious damage.
Properly stored batteries are less likely to have problems if maintained during storage. Using a good charger, not a trickle charger, is the better way to go. There are chargers with a "float", "storage" or "maintenance" mode. A battery "tender" will cycle on and off to keep the battery at the right level without over charging.
Remember that the original Model A system is 6 volt so make sure the charger has that capability. Ensure the terminals are clean before connecting the charger. Using an electrolyte grease will reduce corrosion on the terminals.
Bring the battery into a heated area where you have access to service it as required.
Most 6 volt batteries these days are the "low maintenance" type. This is important as the charging is not the same as "no maintenance" modern batteries. Check the setting on the charger to make sure you have the correct setting.
If you leave the battery in the car, disconnect the battery cables. Using a "quick disconnect" makes the operation a little easier. Remember to disconnect the charger when making any changes. Use caution when charging as the battery will give off hydrogen gas so only charge in a well ventilated area.
The old story about not storing a battery on concrete is not as critical as in the past. Most batteries now have a plastic case which does not react with cement the way the early ones did. To be safe rather than sorry it would not hurt to use a piece of wood under the battery.
Hope this helps getting a quick start as soon as the weather warms up!
