Hi,

If you are referring to cold cranking amperage (CCA), that is too small. The original equipment battery provided 730 CCA.

I attached the specifications below related to the battery. Take a look and let me know if that is what you were referring to and if you have other questions.

Take care,

Joe

Hello,

The catalog calls for a H7 battery for this Jeep Grand Cherokee 3.7L.
If you are mentioning the Cold cranking amp then it will need to have 730 CCA.

Let me know if you have any questions.

Thank you.
