If I use a DC plug in my AC generator head can I charge a battery?

I guess the question might be a little confusing. I didn't know how to word it into a question. But allow me to explain: I have an AC generator head. A pretty big one I must say I think it's around 3.5K Watts full throttle. I live near a river and it seems like the wind is always blowing and quite strongly too. I'd say around 10 m.p.h. 10 out of 14 days. ANY who. If I use the Generator head and then use a DC head cord thing (like the one used to power a Nintendo like back in the day that big ol' box you plug into the wall which converts AC to DC) If I use one of them cords could I trickle charge a battery? I don't see why not, but I'm not 100% sure if someone has experience with this please share your info with me I would sure appreciate it. Thanks!
