How Do You Fix A Broken Xbox 360 Battery Pack?
• Make sure that there IS an actual battery leak in the battery pack! • Get some cotton swabs; about 3-6 would work. • Wet some cotton swabs and dig in the battery pack at the brown stuff in the back and the metal pieces, CAREFULLY. Because you could break a metal piece in the back and it will never work again. • You will notice that there is a brown tint to the cotton part of the swab and some black pieces on it. This is OK • Repeat this step multiple times until you notice it is cleaner than before. Then use your dry cotton swabs to dry out your Xbox 360 controller battery pack, and be sure it is dry before you put it back into your controller!
