So, buckle up and get ready to learn everything you need to know about cold cranking amps and how they keep your car running smoothly, even in the coldest conditions.
Understanding Cold Cranking Amps (CCA)
What are Cold Cranking Amps?
Cold Cranking Amps (CCA) is a measure of a car battery’s ability to deliver a high electrical current in extremely cold temperatures. It represents the number of amperes a fully charged battery can continuously deliver for 30 seconds while maintaining a voltage of at least 7.2 volts at 0 degrees Fahrenheit (-18 degrees Celsius). This is a crucial factor because as temperatures drop, the internal resistance of a battery increases, making it harder to start the engine.
Think of CCA as a measure of a battery’s “cold-weather toughness.” A higher CCA rating indicates a stronger battery capable of providing the necessary power to crank your engine even in freezing conditions.
Why are CCA Important?
The importance of CCA becomes evident during cold starts. When temperatures plummet, the engine’s oil thickens, making it more difficult for the starter motor to rotate the engine crankshaft. A battery with insufficient CCA might struggle to provide enough current to overcome this resistance, resulting in a slow crank or even a complete failure to start.
Consider these scenarios:
Even a relatively new battery might lose its CCA over time due to aging or improper charging.
How CCA is Measured
CCA is determined through a standardized laboratory test. During the test, a battery is subjected to a controlled discharge while being cooled to 0 degrees Fahrenheit. The maximum current it can deliver for 30 seconds is recorded as its CCA rating. This test simulates the demanding conditions encountered during a cold start.
Factors Affecting CCA
Several factors influence a car battery’s CCA rating:
- Battery Chemistry: Different battery types, such as lead-acid, AGM, and lithium-ion, have varying CCA capabilities.
- Battery Size and Capacity: Larger batteries with higher amp-hour (Ah) ratings typically have higher CCA.
- Battery Age and Condition: As batteries age, their CCA gradually declines.
- Charging Practices: Improper charging can negatively impact CCA.

How is CCA Measured?
Cold Cranking Amps is measured using a specialized test device that simulates the load of an engine starter motor. The test device applies a load to the battery and measures the current output. The battery is then discharged at a specific rate, and the current output is measured over a period of time.
The CCA rating is calculated by dividing the total energy delivered by the battery by the time taken to deliver it. The resulting value is expressed in amps, with higher values indicating a more powerful battery.
Factors Affecting CCA Ratings
Cold Cranking Amps is influenced by several factors, including:
- Battery type and chemistry
- Battery age and condition
