I am going to get my car battery replaced or I am going to get battery of my car replaced? [closed]

Solution 1:

Car battery.

In English, anything that belongs to the car is called "car" something. Car door, car keys, car bonnet, etc.

I teach ESOL, and notice that a lot of non native speakers of English say and write things like "my car's door" or "the door of my car", which are logical, but not what we say.
