A battery with a sufficient CCA rating can better support these systems and ensure they function properly.

Moreover, a battery with a higher CCA rating is likely to have a longer lifespan. Batteries degrade over time, and their CCA rating gradually decreases. Starting with a battery that has a higher CCA rating means that it will take longer for the CCA to drop below the minimum required level. This can save you money in the long run by reducing the frequency of battery replacements.

Another reason why CCA matters is that it can affect the performance of other electrical components in your Mazda CX-5. A weak battery can cause voltage drops, which can lead to erratic behavior or even damage to sensitive electronic systems. By ensuring your battery has a sufficient CCA rating, you can help maintain a stable voltage and protect your car's electrical components.
