What you are effectively doing is preventing the chemical reaction that produces the voltage from ever happening. It will not harm your batteries. Just make sure you give them enough time to thaw before you intend to use them. NEVER FREEZE ANY BATTERY WHICH CONTAINS WATER (obvious reasons). In addition, placing batteries in a cooler (not freezing) will prolong the life of the batteries. Brian Hall
