Your post is very difficult to understand because there is no punctuation, but I think I have the basics of what you are asking.

First, check the condition of the pulleys to make sure that the belt is not being worn away. Are they all even? Smooth inside? Is there belt dust around the area?

Are you over tightening the belt?

When you connected the new battery, did you connect it backwards?
