Cold cranking amps
What’s the definition of cold cranking amps? Battery ratings require time and temperature standards To properly rate a battery’s jumping ability, you have to test it at an industry defined temperature, for an industry defined time period, with an industry defined maximum drop in voltage. Here’s the definition of cold cranking amps: Cranking amps definition Cranking amps (CA) refers to the number of amps a battery can output at 0°F (-17.8°C) for 30-seconds while still maintaining at least 7.2 volts. The reason cranking amps is more important than peak amps … Read More
What are Cold Cranking Amps
What does cold cranking amps do I need for my new car battery? Car batteries are rating using several different tests like: cold cranking amps (CCA), cranking amps and reserve capacity. Of these ratings, CCA is probably the most important. Since a lead acid battery produces power through a chemical process, it’s sensitive to outdoor temperatures. In cold weather this chemical process slows down and produces less power. Cold cranking amps The official test to determine a battery’s CCA rating requires the battery to be chilled to 0°F (-17.8°C). Then … Read More
