Dell shows two batteries for that laptop. Parts-People also shows two types, though they are currently out of stock. It's good that you caught it.  A swelling battery can damage components such as touchpad and keyboard. Please do not throw it in the garbage. Take it somewhere that it will be properly disposed of. In many places, stores such as Best Buy and Staples will accept old "tech" for proper disposal/recycling. A recycling depot may also accept batteries. These links should be helpful to you: Swollen Battery Information and Guidance | Dell Canada How Do I Recycle or Dispose of My Dell Battery | Dell US Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
