ZenBook Battery Replacement: What You Need to Know

ZenBook ultrabooks use ultra-slim Li-polymer batteries that require precision matching for both fit and power delivery. Locate the part number on your existing battery (e.g. C31N1901, B31N1730, C41N1904) or use your ZenBook model number to find an exact replacement. Due to the slim form factor, handle the battery carefully during installation — avoid bending or puncturing the cell.

Signs Your ZenBook Battery Needs Replacing

• All-day battery life (10+ hours) has dropped to 3–4 hours
• Battery percentage jumps erratically or drops suddenly during use
