Quick Answer
Alkaline batteries can be used in winter, but their performance and lifespan may be significantly reduced.
Performance in Cold Temperatures
Alkaline batteries start to degrade in performance at temperatures below 60°F (15°C). At 32°F (0°C), their capacity is reduced by about 35%, and at 14°F (-10°C), their capacity is cut in half. This means they will not deliver the same amount of power as they would in warmer temperatures.
Using Alkaline Batteries in Winter
If you must use alkaline batteries in winter, choose high-capacity batteries (e.g., AA or AAA batteries with a 3000mAh rating). Store them in a warm, dry place (above 50°F or 10°C) for at least 24 hours before using them in cold temperatures. Keep them away from moisture and extreme cold.
Alternatives to Alkaline Batteries
Consider using lithium batteries, which maintain their performance and capacity in cold temperatures. Lithium batteries are available in the same sizes as alkaline batteries and have a longer lifespan (up to 10 years). They are also more energy-dense and can power devices for longer periods. If you plan to use batteries in extreme cold, consider investing in lithium batteries as a more reliable option.
