Cold Cranking Amps (CCA) is a rating used to describe a battery’s ability to start an engine in cold temperatures. CCA measures the number of amps a battery can deliver at 0°F (-18°C) for 30 seconds and maintain a voltage of at least 7.2 volts for a 12-volt battery or 14.4 volts for a 24-volt battery.

In cold temperatures, a battery’s performance is reduced due to the slower chemical reaction inside the battery. The CCA rating indicates the battery’s ability to deliver enough power to the starter motor to crank the engine and overcome the increased resistance caused by the cold temperatures.
A higher CCA rating means that a battery can deliver more power to the starter motor and is more likely to start the engine in cold temperatures. However, a battery with a higher CCA rating may also be more expensive, heavier, and have a shorter lifespan.
It is important to select a battery with a CCA rating that is appropriate for your vehicle’s make and model and the typical cold temperatures in your area. A battery with a CCA rating that is too low may struggle to start the engine in cold temperatures, while a battery with a CCA rating that is too high may be unnecessary and add unnecessary cost and weight.
Overall, CCA is an important rating to consider when selecting a battery for your vehicle, particularly in areas with cold temperatures. A higher CCA rating can provide added assurance that your vehicle will start even in extreme cold conditions.
