Signs the Battery Needs Replacing

  • The laptop shuts down soon after unplugging
  • Battery time has dropped sharply
  • The charge percentage will not rise
  • The pack swells or the base lifts

Why Replace It Early

A tired pack leaves a work laptop tied to a socket, and a swelling one can press on the trackpad or crack the case. Replacing it early keeps the laptop safe and portable.

What You Get

You receive a new B31N1915 battery pack with warranty from QASWATEC. Our team can check the fit for you before you buy, so you avoid a wrong order and a second trip to the shop.

Care Tips for Longer Life

  • Avoid draining the pack to zero often
  • Keep the vents clear of dust
  • Do not leave it at 100 percent for days

A cooler pack ages slowly, which slows capacity loss.
