Quick Answer
Battery ratings that indicate cold weather performance include the Cold Cranking Amps (CCA) and Marine Cranking Amps (MCA) ratings, which are measured at 0 degrees Fahrenheit or -18 degrees Celsius. Another rating to consider is the Reserve Capacity (RC), which shows a battery's ability to power a device for a certain period in cold temperatures.
Understanding Cold Weather Battery Ratings
Cold Cranking Amps (CCA) is the most commonly used rating to measure a battery’s performance in cold temperatures. It measures the number of amps a battery can deliver for 30 seconds at 0 degrees Fahrenheit (-18 degrees Celsius) to start an engine. A higher CCA rating usually indicates better cold weather performance, with most deep cycle batteries ranging from 350 to 1200 CCA.
Battery Selection for Cold Weather Gear
When selecting a battery for your gear in cold weather, look for batteries with a high CCA rating. For example, if you want to power a 25-pound trolling motor in cold temperatures, you would need a battery with a CCA rating of at least 400-500. Consider also the battery’s Reserve Capacity (RC), which measures its ability to power a device for a certain period. A higher RC rating usually indicates a more reliable battery in cold temperatures.
Additional Factors to Consider
Other factors to consider when selecting a battery for cold weather gear include the battery’s age and maintenance. Old or poorly maintained batteries can perform poorly in cold temperatures, even if they have a high CCA rating. Make sure to check the battery’s date code and ensure it has been properly charged and maintained before use in cold weather conditions.
