The batteries I am working with are: Energizer Lithium Photo, Duracell D Alkaline, and Rayovac D Zinc-Chloride. Any help would be appreciated!

Remember that molecules move slower when the are colder.
Because batteries use chemical reactions create electricity, the amount and flow of power is dependant on how fast the molecules are moving. Normally batteries are kept around room temperature, so they work at the voltages listed on the pack.
However, when you subject them to a cold environment, the atoms start moving slower, and the voltage and amperage decrease.
Also- remember that the voltage listed on the pack is based on a reading of the voltage at room temperature. Anything else is changing that variable, and therefore may change your overall outcome.
Hope this helps.

The power of the battery decreases with temperature. The reason this occurs is because the baterry power is produces as a result of chemical reaction. The reaction rate decreases with temperature.

Chemical reactions typically depend strongly on the temperature. Once you get to reaction rate equations, you'll see the temperature variable showing up.

the cold slows the reactions inside the battery, making them weaker
