CCA rating is used to determine the battery’s ability to crank an engine in very cold temperatures when the chemical reaction inside the battery slows down. A battery puts out 100 percent of its rated power at 27 degrees Celsius, 65 percent at 0 degrees, and only 40 percent at -18 degrees. CCA is great for comparing battery performance in cold climate areas. But in hot climates, batteries with extremely high CCA ratings may have a shorter life!
CA is the discharge load in amperes at which a new and fully charged battery at 0 degrees Celsius can continuously deliver power for 30 seconds while maintaining a voltage equal to or higher than 1.20 volts/cell. CA ratings can be misleading because they can be up to 30 percent higher than the equivalent CCA rating!
RC is the number of minutes a new, fully charged battery at 27 degrees Celsius can be discharged at 25 amperes while maintaining a voltage of 1.75 volts per cell or higher. For a 12-volt car battery with six cells, RC is the number of minutes it can hold a voltage of 10.5 volts with a 25-amp draw. Many modern cars with lots of accessories can see a current discharge rate much greater than 25 amps. Basically, the bigger the battery’s RC, the better!

You depend on your car to get you where you need to go, so when it doesn’t start, it can be a pretty big problem. How do you know if it’s the alternator or battery? Knowing the difference between their defaults will let you make a quick diagnosis and the proper repairs.
Once the engine is running on its own, the charging system takes over, generating current to recharge the battery and power the vehicle’s lights, audio, climate control, navigation, and other systems. Here’s how to maintain your car’s battery and charging system for reliable performance, no matter the weather!
