Cold Cranking Amps (CCA)
CCA is the current a battery can deliver at -18 °C for a set time while keeping enough voltage.
What is Cold Cranking Amps (CCA)?
It is printed on the battery label. Diesels and large engines need higher values. Different standards, such as SAE and EN, measure CCA in slightly different ways, so values on labels are not always directly comparable.
How it works
Higher CCA means stronger starting power in cold weather.
Why it matters for your car
Choose at least the value specified for your car. A battery tester measures how much of the rated CCA the battery can still deliver, which shows its state of health.
