Understand that battery ratings describe different performance characteristics of a battery under specific conditions.
Recognize that Cold Cranking Amps (CCA) measures the battery's ability to start an engine in cold temperatures, specifically tested at 0 °C (32 °F).
Know that Hot Cranking Amps (HCA) is tested at a higher temperature (usually 80 °F or 27 °C) and measures starting power in warm conditions.
Reserve Capacity (RC) indicates how long a battery can supply a certain load before dropping below a usable voltage, not related to temperature testing.
Ampere-Hour (Ah) measures the total charge capacity of a battery over time, independent of temperature testing conditions.
