Making the right choices will enhance the performance of your vehicle.

Cold Cranking Amps (CCA)

Cold Cranking Amps (CCA) is the measurement of a battery’s ability to start an engine in cold temperatures. CCA is a crucial specification because it tells you how much power the battery can provide at 0°F (-18°C). A higher CCA rating means the battery can deliver more power in cold weather, which is important for starting your F-150. If you live in a cold climate, choosing a battery with a high CCA rating is a good idea. This ensures reliable starting, especially during the winter months.

• Why CCA Matters: A higher CCA rating provides more power, which allows your engine to start reliably in cold temperatures. Cold temperatures make engines harder to start because the oil thickens, and the battery’s chemical reactions slow down. A battery with a good CCA rating overcomes these challenges. Always match or exceed the CCA recommended by your vehicle’s manufacturer.
• Matching CCA to Your Needs: The required CCA rating varies depending on the engine size and type. Larger engines need more power to start. Consider the climate you live in. If you live in a place with cold winters, choose a battery with a higher CCA. Consult your owner’s manual or an auto parts professional for the recommended CCA.
• CCA vs. CA (Cranking Amps): Cranking Amps (CA) is another measure of a battery’s starting power. It’s measured at a higher temperature, typically 32°F (0°C). CCA is generally a more important metric for most vehicle owners. When purchasing a battery, always give preference to the CCA rating.

Reserve Capacity (RC)

Reserve Capacity (RC) is the time, in minutes, that a battery can supply a certain amount of power at 80°F (27°C). It represents the battery’s ability to keep your car running if the charging system fails. A higher RC means that the battery can keep your truck’s electrical components running for a longer time. This feature is particularly helpful if you accidentally leave your lights on or if your charging system has problems.

• What RC Means: The RC rating indicates how long a battery can provide a sufficient amount of power before it is fully drained. It is a critical feature, providing you with a safety net in case of electrical system issues. A higher RC provides more time to address a charging problem or prevent being stranded. You can use this to keep your truck running in emergency situations.
• Choosing the Right RC: Choosing a battery with a higher RC can offer extra protection. However, the recommended RC is usually determined by the vehicle’s electrical demands. Consider your usual driving conditions and the potential for electrical system issues. A higher RC is especially helpful if you often use accessories.
