Shop Lenovo parts
Yes, most Lenovo laptop batteries can be replaced. The difference is how easy it is. Older models may have external batteries, while most modern ThinkPad/IdeaPad/Yoga/Legion devices use internal batteries accessed from the bottom cover.
What type of Lenovo battery do you have?
- External battery (less common today): quick swap.
- Internal battery (most common): replaceable, but requires opening the bottom cover.
- Dual-battery/Power Bridge (some ThinkPads): you may have an internal + external battery.
Before replacing: avoid Lenovo-specific confusion
- Check Lenovo Vantage for charging thresholds (60–80% is normal in conservation mode).
- If charging is unstable, confirm your charger wattage (USB-C PD must be strong enough).
Pick the correct replacement
- Use the battery FRU/Part Number printed on your old battery.
- Match voltage (V), capacity (Wh), and connector.
