"The rating used to define a battery's ability to start an engine in cold temperatures is called Cold Cranking Amperage (CCA). The CCA of an auto battery is the amount of current a given battery can deliver for 30 seconds at 0 °F (-18 °C) without dropping below 7.2 volts for a 12 volt battery. To find the power of a car battery we multiply the CCA number by 7.2 volts.
For example, P = IV P = (600 A)(7.2 V) P = 4320W
Most modern cars require relatively low cold cranking amps that range from 400 to 600. Sports cars and light trucks require higher cranking amps ranging from 700 to 1000."
The test procedure appears to be standardised for all manufacturers. But I think that CA or Cranking Amperes also exist, from a test at a higher temperature.
Define the difference between MCA and CCA. MCA = CA
The marine cranking ampere (MCA) rating of a battery is very similar to the CCA rating; the only difference is that while the CCA is measured at a temperature of 0°F, the MCA is measured at 32°F. All other requirements are the same — the ampere draw is for 30 seconds and the end of discharge voltage in both cases is 1.20 volts per cell.
As for the Accord battery, it is the same as the one installed in Civics and not much bigger than a motorcycle battery. The 410 CCA then makes sense. Honda has always put small batteries in its cars.
And even if a canadian spec Corolla comes from the same canadian or US plant as US bound Corollas, doesn't necessarily mean that alternator, battery and starter are the same?
That was the reason behind my questionning of the battery and alt power of US 03+ Corollas of fellow US members of this great forum...
