winch battery recommendations

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.

I had a winch reinforcement plate welded under the floor off to the side on the new trailer. Will be adding the battery/box right beside it against the side wall. I figured a center mounted winch would be a constant nuisance with a cable stretched out right in the middle of where the pit bike/golf cart will be tied down.

I have a group 27 deep cycle battery mounted under the bench. It is wired to charge from the tow vehicle going down the road and I use a battery tender when it sits in the yard.


I did this when I purchased the trailer in 2010 and I have had no issues.
