Question

What is the difference between cold cranking amps (CCA) and reserve capacity (RC)?

Answer

CCA measures the battery's ability to start an engine in cold weather, while RC indicates how long the battery can supply a minimum voltage under a constant load.

Explain

Both parameters are important; CHEPQ testers provide comprehensive readings to evaluate batteries for both starting power and long-term energy supply needs.
