How to Replace a Lenovo Laptop Battery: Step-by-Step Guide (2024)

Are you sad when your Lenovo laptop dies too fast? You need a new battery! This guide helps you fix it all by yourself. No need to pay a shop to do it!

Signs You Need a Battery Replacement

How do you know when it’s time for a new battery? Look for these signs:

• Battery drains super fast
• Laptop turns off when not plugged in
• The battery looks puffy or fat
• Your ThinkPad X1 Carbon or other Lenovo model has low “battery health” in the Lenovo Vantage Tool
  You can check your battery health with the Lenovo Vantage Battery Health Tool. This tells you if your 3391mAh laptop battery is still good.

Finding the Right Replacement Battery

Getting the right battery is very big! You need to:

1. Check your old battery label
   • Look for model codes like “L19M3PF1” for ThinkBook 15 G2
   • Find the voltage (like 11.7V or 15.48V power cells)
2. Pick between types:
   • OEM Lenovo laptop battery (made by Heyuan High-Tech Batteries)
   • Non-OEM battery alternatives (cheaper but may not last as long)

“A genuine Lenovo battery costs $80-$120 while third-party options run $30-$60. Genuine batteries often last twice as long.”
