Lenovo parts
In many cases, yes—you can replace a Lenovo laptop battery yourself, especially when the bottom cover is screw-mounted and the battery is clearly accessible. The key is ordering the correct battery (FRU/Part Number) and avoiding risky situations.
DIY is usually OK if…
- The bottom cover opens cleanly without forcing clips.
- You can keep track of screws and reassemble carefully.
- You have the correct replacement battery identified by FRU/Part Number.
Use caution (or use a service) if…
- The laptop is ultra-thin and heavily clipped.
- There’s a suspected charging-port issue in addition to battery problems.
- Safety red flags: battery swelling, unusual heat, smell, or chassis deformation.
How to order the correct battery first time
- Match the printed FRU/Part Number.
- Verify V, Wh, and connector shape.
- On some ThinkPads, confirm internal vs external battery.
