Replacement Battery for ThinkBook 14 and 15

The KingSener L19C4PDB is a new lithium-ion battery rated at 15.44V and 3912mAh, delivering 60WH of capacity. It matches the original part numbers L19C4PDB, 5B10Z21209, SB10Z21205, L19M4PDB and 5B10Z21201. The black pack weighs 242g and is built for Lenovo ThinkBook 14s Yoga ITL, ThinkBook 14 G2 and G3, ThinkBook 15 G2 and G3 models.

Straightforward Swap with Model Verification

Installation follows the standard ThinkBook bottom-case removal process: unscrew the base, disconnect the old pack, connect the new one and reassemble. The main risk is ordering the wrong variant, because not every compatible model appears in the list. Opening the laptop to read the original battery model number before purchase avoids mismatches.

For ThinkBook Owners Needing a Direct Replacement

This unit suits users whose ThinkBook 14 or 15 G2 and G3 batteries have degraded and who can confirm the exact part number on the existing pack. It is not for buyers who cannot access the internal battery label, for machines outside the listed ThinkBook series, or for anyone needing a different voltage or capacity.
