ASUS A31N1519 3-Cell 36Wh 11.1V Laptop Battery for ASUS X540 Series

When an ASUS X540 laptop dies the moment the charger is pulled, the battery is almost always the cause.

Signs the Battery Needs Replacing

• Backup time has fallen to a few minutes
• The battery percentage drops suddenly or jumps
• The laptop shows plugged in but not charging
• The base of the laptop looks bulged or lifted

Why Replace It Early

A weak battery turns a laptop into a desktop that must stay plugged in. During load-shedding a power cut then shuts the machine down instantly and unsaved files can be lost. A fresh pack restores real mobility for students, office users and shop owners.

What You Get

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

Care Tips for Longer Life

• Use the original charger or a good quality adapter
• Avoid leaving the laptop at 100 percent on charge for weeks
• Keep the vents clear so heat does not age the cells
• Charge it fully the first time after fitting
