Effects of Temperature on Battery Performance

Overview

I am a Remote Control car fan. I drive my cars throughout the year. In the winter, the battery drains faster than it does in the summer time. This led me to have the question of how does temperature affect different types of battery performance? For my Science Fair, I investigated how temperature affects battery performance. I exposed three different types of 9-Volt batteries; Alkaline, Lithium and Nickel-Metal Hydrate (NiMH) to three different temperatures; warm, cold, and freezing and then tested the voltage of each battery to see if the temperature impacted each battery’s performance. My testing showed that the cold temperatures did have an effect on the batteries' performance. This information would clarify how temperatures can affect the performance of anything running on a battery, such as Electric cars and phones and which types of batteries preform best in cold temperatures.
