Quick Answer
Batteries typically last 30-50% of their normal lifespan in extreme cold weather, which is defined as temperatures below 32°F (0°C).
Battery Discharge Rates in Cold Weather
Battery discharge rates drop significantly in cold temperatures. For every 10°F (5.6°C) drop in temperature, battery discharge rates decrease by 50%. This means a battery that normally lasts 10 hours at room temperature may last only 5-6 hours in 20°F (-6.7°C) temperatures.
Cold Temperature Battery Storage Tips
To extend the lifespan of batteries in cold weather, store them in a warm place (above 50°F or 10°C) when not in use. If this is not possible, store them in an insulated container or bag. Avoid exposing batteries to cold temperatures for extended periods, as this can cause permanent damage.
Common Batteries and Cold Weather Performance
Most AA, AAA, and D-cell batteries experience a moderate decline in performance in cold temperatures. However, some batteries like lithium-ion and alkaline batteries tend to perform better in cold weather than others. Nickel-cadmium (Ni-Cd) batteries, on the other hand, tend to degrade faster in cold temperatures. Check your specific battery type for its expected performance in cold weather.
