Lenovo 01AV421 Replacement Battery Review
Lenovo 01AV421 replacement battery, the 3-cell 11.46V 24Wh internal front battery for the ThinkPad T470 and T480, also listed by Lenovo for the A475, A485 and ThinkPad 25.
The T470 and T480 run two batteries at once. This is the fixed one inside the base, reached by removing the bottom cover. Lenovo treats 01AV419, 01AV420, 01AV421 and 01AV489 as interchangeable service parts for it.
What to check before you buy
Disconnect the internal battery in the BIOS (Disable Built-in Battery) before opening the base cover. This pack is separate from the removable rear battery, which is a different part.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- ThinkPad T470 and T480 owners whose internal battery no longer holds charge
Not for
- The removable rear battery (01AV424, 01AV425 or 01AV427 families)
