Signs the Battery Needs Replacing

• The laptop turns off soon after unplugging
• Backup time is only a few minutes
• Battery percentage drops or jumps suddenly
• The laptop is plugged in but not charging

Why Replace It Early

A worn battery ties a laptop to the wall. In a power cut the machine switches off at once and unsaved work can be lost. A fresh pack gives travellers and office users real mobility again.

What You Get

You receive one new battery pack ready to fit into your ASUS laptop. It is checked before sale, and you can ask our team to confirm the fit against your old battery before you pay.

Care Tips for Longer Life

• Use the original charger or a good quality adapter
• Do not keep the laptop at 100 percent on charge for weeks
• Keep the vents clean so heat does not age the cells
• Charge the new battery fully the first time
