What is CCA?
If you're shopping for a new car battery, you might notice that different batteries offer different CCA ratings. But what does CCA mean on a battery? CCAs, or cold cranking amps, describe how well a battery can start a car under cold conditions. Standard CCA refers to classic 12-volt car batteries – the higher the CCA, the better the battery is at starting in the cold.
How Many CCAs Do You Need?
Car and truck batteries are primarily used for starting up your engine and powering your lights and vehicle accessories. Once the engine starts, the alternator supplies power to your car, so the main job of your battery is to give you a short and strong burst of energy.
So, if your battery is used as a starting power, you might be wondering how many CCAs you really need? The main considerations will be the climate you live in and the model of your car. Typically, warmer climates require lower CCAs, since it's easier to start up a car battery in warm temperatures. If you live somewhere with very cold winters, it might be worth shopping for a higher CCA.
Your vehicle manufacturer can also help you find how many CCAs are best for your car. The amount of start-up power you need also depends on your engine size, circuit resistance and accessories, so consult your vehicle handbook or drop by your local Batteries Plus Bulbs location for help finding the best car battery for your needs.
