In reality, CCA specifications vary by battery technology, such as lead-acid, lithium-ion, and AGM (Absorbent Glass Mat) batteries. Each type has distinct construction and performance characteristics affecting its CCA rating. For example, lithium-ion batteries generally have lower CCA ratings compared to lead-acid batteries due to their different chemical storage mechanisms. -
Higher CCA always indicates a better battery:
The belief that a higher CCA rating always means a better battery is misleading. While higher CCA can be beneficial for starting larger engines in cold weather, it does not account for other factors like battery longevity, reliability, or overall efficiency. Users must consider their specific needs, such as climate and vehicle requirements, instead of focusing solely on CCA numbers. -
CCA testing is not influenced by temperature:
The notion that CCA testing is not affected by temperature is a common myth. In fact, temperature plays a significant role in battery performance. CCA ratings are defined at specific temperatures, and testing at wide fluctuations in temperature can lead to false readings. For instance, a battery may perform poorly at cold temperatures but show acceptable performance at warmer temperatures, impacting its practical utility for end-users. -
CCA provides a complete assessment of battery health:
Lastly, the misconception that CCA provides a complete assessment of battery health is incorrect. CCA only measures the ability to deliver starting power under specific conditions.
