Check your exact model

Verify that your laptop is a ThinkBook 14-IML, 14-IIL or 15-IIL before ordering. This battery does not work with the ThinkBook 14s variant. Match your original part number against the supported list such as L19C3PF0, L19M3PF1, L19D3PF1, 5B10X55572 or 5B10V25250.

Questions about this item

Does the battery come with any tools or cables for installation?

The package contains only the battery itself; no screwdrivers, cables or mounting hardware are included.

Should I pick the 45 Wh or the 57 Wh version for my ThinkBook 14-IIL?

The supplier ships either the 45 Wh or the 57 Wh unit depending on stock; both share the same part numbers and fit the listed ThinkBook 14 and 15 models.

The label shows four different voltages — will the 11.55 V variant work safely in a laptop that originally used 11.1 V?

Yes, the manufacturer states that L19C3PF1, L19L3PF1 and L19M3PF1 are interchangeable despite the voltage differences, so any shipped unit will operate correctly.
