• The laptop shuts down at a middle charge level
• Runtime has fallen far below the original
• The charge level will not rise
• The base cover lifts or bulges

Why Replace It Early

Thin business laptops have no space for a swelling pack, which can crack the cover or press the trackpad. Replacing it early protects the body and keeps you working away from a socket.

What You Get

You receive a new C41N1903 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 laptop away from heat
• Do not leave it at 100 percent for days

A cooler pack ages slowly, which slows capacity loss.
