Lenovo L21M4P71 Replacement Battery Review

Lenovo L21M4P71 replacement laptop battery, a 15.48 V, 52.5 Wh OEM pack listed for the Lenovo ThinkPad P14s Gen 5 AMD.

The L21M4P71 is an OEM-sourced battery rated at 15.48 V and 52.5 Wh. The only laptop listed for it is the Lenovo ThinkPad P14s Gen 5 AMD with the Ryzen 7 PRO 8840HS, 32 GB and 1 TB configuration. The 52.5 Wh capacity is a seller claim, not a figure we measured, so treat it as the listed rating. Shipping is classified UN3481. If your ThinkPad is a different model or generation, check the battery code on your old pack before ordering, because this listing names a single laptop and no alternate part numbers.

What to check before you buy

This code spans several ThinkPad T14 and P14s generations. Confirm against your specific Gen 5 AMD unit before ordering.
