The winch is rated at 4500 pounds if that makes any difference. Thanks for any input in advance.

In my opinion you need a deep cycle. My son manages the local Interstate dealership and he fixed me up with two Interstate deep cycle batteries. They are over five years old still strong.

My trailer came with two batteries although I think most just come with one. They mount in battery boxes on the tongue, however I notice in a lot of new trailers they mount under the counter in a battery box that is vented to the outside.
