  • Cold Cranking Ampere (CCA): 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 -18 °C (-0.4 °F) 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.
  • RESERVE CAPACITY (RC) : Reserve Capacity is a battery industry rating, defining a battery's ability to power a vehicle with an inoperative alternator or fan belt.
    • The rating is the number of minutes a battery at 26.7 °C (80 °F) can be discharged at 25 amps and maintain a voltage of 10.5 volts for a 12 volt battery.
    • The higher the reserve rating, the longer your vehicle can operate should your alternator or fan belt fail.
