Quick Answer
While there are many battery brands available, some are specifically designed to perform well in cold weather, including Goal Zero, Anker, and Energizer. These brands offer batteries with low-temperature performance and long shelf life.
Battery Performance in Cold Weather
When choosing a battery for cold weather use, look for one with a low self-discharge rate and a voltage that remains stable at low temperatures. Some batteries, such as lithium-ion batteries, tend to perform better in cold weather than others, like alkaline batteries. For example, Goal Zero’s lithium-ion batteries maintain 90% of their capacity in temperatures as low as -20°C.
Cold Weather Battery Testing
To determine the performance of a battery in cold weather, look for testing data provided by the manufacturer. Anker’s PowerCore batteries, for example, have been tested to retain 80% of their capacity in temperatures as low as -10°C. When choosing a battery, also consider the type of device it will be powering and the expected duration of use. A battery that can provide a full charge to a device in 30 minutes at -20°C is likely a better choice than one that takes several hours to charge at the same temperature.
Battery Selection for Extreme Cold
For use in extremely cold weather, such as in Arctic or Antarctic environments, consider a battery with a high energy density and a low self-discharge rate. Energizer’s Ultimate Lithium batteries, for example, have a 20-year shelf life and maintain 80% of their capacity in temperatures as low as -40°C. When selecting a battery for extreme cold, also consider the type of device it will be powering and the expected duration of use, as well as any environmental factors that may affect battery performance, such as humidity and wind.
