Hi there,
Using a marine battery in your car can lead to several issues, especially because automotive and marine batteries are designed for different applications. Here are some reasons why:
1. Marine batteries are designed for deep cycle applications wherein they provide sustained power over a long period. It may not deliver the high-cranking amps needed to start the engine. Car batteries are designed for short, high-current bursts to crank the engine.
2. Mismatch is the voltage and amperage. If those two aspects do not match, it will result in a condition that you are experiencing.
3. It is best to replace it with a car battery that meets the CCA requirements for your 2012 Mazda CX-9.
4. Other electrical issues. While less likely, there might be other underlying electrical problems in your car causing the no-crank and no-start condition. If you replace the marine battery with a car battery the problem remains. It is best to have your car checked by a certified mechanic.
