Hey @corpsecatfan1! Aside from replacing the battery, have you also tried cleaning the battery bay with a dry cloth or non-abrasive anti-bacterial wipes? If not we'd recommend trying that, but please don’t use alcohol or an abrasive cleaning solution. Additionally, we wouldn't recommend putting any foil or anything into your controller as that could potentially cause further damage.
Are you seeing any lights on the controller that are on (blinking or solid)? Any vibrations? And is the right controller working fine?
