You have not specified the battery model. It should be in your topic title.

It's not. When you you connect it PRES bit will be active, now it's not.

Output LED can be off for another reason. First find SP pin.

 Please return back initial cycle counter and production date. They have nothing to do with charge or discharge issues.
