Signs the Battery Needs Replacing

• The Ultrabook powers off at a middle charge level
• Battery time is much shorter than it used to be
• The charge percentage will not rise
• The pack bulges or the bottom cover lifts

Why Replace It Early

The S7 body is thin, so a swelling pack can crack the cover or press the trackpad. Replacing it early avoids repair costs and keeps the Ultrabook usable on the move.

What You Get

Care Tips for Longer Life

• Avoid deep discharge to zero
• Keep it away from heat and direct sun
• Do not keep it on charge at 100 percent for days

These habits reduce heat in the cells, which slows capacity loss.
