Lenovo L23D4P71 Replacement Battery Review
Lenovo L23D4P71 replacement laptop battery, a 15.48 V, 52.5 Wh OEM pack listed for the Lenovo ThinkPad T14 Gen 5, replacing L23B4P70, L23C4P73 and L23M4P72.
The L23D4P71 is an OEM-sourced battery rated at 15.48 V and 52.5 Wh. The listed laptop is the Lenovo ThinkPad T14 Gen 5 with a Core Ultra 7 155U, 16 GB and 512 GB. It also replaces the part numbers L23B4P70, L23C4P73 and L23M4P72, so any of those on your old pack's label point to this one. The 52.5 Wh capacity is a seller claim rather than a measured figure.

What to check before you buy
Confirm Gen 5 on the base of your T14, since Lenovo has cycled through several battery codes across ThinkPad T14 generations.
