What Are Cold Cranking Amps?In order to understand where the term “Cranking Amps” comes from, it is important to understand the history behind traditional automobile engines. Prior to the electric car starting system, a hand crank was used to turn over the engine. This was a dangerous task...
"Cold cranking amps" is one of those phrases that's commonly tossed around when discussing truck and auto batteries. It's often used as a way of showcasing a battery's capacity, with the implication being that a higher number of CCAs equals a better battery. So, should you buy the bat...
A: When a lead acid battery is fully charged the electrolyte is sulfuric acid with a freezing point of below -40°C. When the battery is fully discharged all the sulfate ions are consumed and the electrolyte is mostly pure water with a freezing point of zero degrees C. So it is not ...
CCA (Cold Cranking Amps) - The number of amps that the battery can produce at 32 degrees F (0 degrees C) for 30 seconds while keeping its voltage above 7.2 volts RC (Reserve Capacity) - The number of minutes that the battery can deliver 25 amps while keeping its voltage above 10.5 vol...
Cold cranking amps (CCA): This is a measure of a battery's capacity to start a car at 0 degrees Fahrenheit (-17 degrees Celsius), when the engine oil is thick and the battery's chemical potential is low. The higher the CCA, the better it will start in the cold. Most batteries list...
