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 thin ultrabook 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 Y9N00 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.

Before You Order

Match the part number and your laptop model. Send a photo of the label if you are unsure.
