What does CCA mean?
Cold Cranking Amps is a rating used in the battery industry to define a
battery's ability to start an engine in cold temperatures. The rating is
the number of amps a new, fully charged battery can deliver at 0°
Farenheit for 30 seconds, while maintaining a voltage of at least 7.2
volts, for a 12 volt battery. The higher the CCA rating, the greater the
starting power of the battery.
What are MCA or CA rates?
This is a rating used to describe the discharge load in amperes which a
new, fully charged battery at 32 degrees F (0C), can continuously
deliver for 30 seconds and maintain a terminal voltage equal or greater
than 1.2 volts per cell. It is sometimes referred to as Marine Cranking
Amps or Cranking Amps.

Yes.
CCA is measured at 0°F
CA is measured at 0°C (cranking amps)
A 1000 CA battery is probably around 750-850 CCA.
