Cold Cranking Amps (CCA) refers to the amount of power that a battery can discharge for 30 seconds at 32°F (0°C). It really is the amount of power you need to start your engine in any weather except winter. However, CCA is used to rate the starting performance of lead-acid battery products' in cold climates, and we normally will not use it to rate your device, which is a lithium-ion jump starter.
Generally, we will use the peak current to measure the jump starter’s performance. Learn more about the peak current:
