Lenovo 01AV423 Replacement Battery Review

Lenovo 01AV423 replacement laptop battery, 11.4V 24Wh 3-cell. Fits Lenovo ThinkPad T470, Lenovo ThinkPad T480, Lenovo ThinkPad T570, Lenovo ThinkPad T580 and more.

Lenovo sells this pack as ThinkPad Battery 61 (option 4X50M08810): 3-cell, 24Wh, 2.08 to 2.10 Ah, 11.40 to 11.55 V nominal. The same rear bay also takes the larger 61+ (48Wh, 01AV425) and 61++ (72Wh, 01AV427 / 01AV492) packs, which stick out further from the base.

What to check before you buy

01AV421 is the internal 24Wh pack in the T470/T480 (Battery 1, inside the base). It is a separate pack for a different bay and is not interchangeable with the removable rear 01AV423 (Battery 2). This pack does not fit the T460s, T470s or T480s, which are different chassis.
