Compatible ThinkBook 14/15 replacement battery

This new GreenTechLLC battery replaces the original Lenovo pack in ThinkBook 14-IML, 14-IIL, 15-IML and 15-IIL models. It uses a 3-cell lithium-ion design rated at 11.1V and 4140mAh for 45Wh capacity. The unit is a direct swap for OEM part numbers such as L19L3PF8 and 5B10V25237. It suits owners who need a fresh power source for daily mobile work.

Verify your exact model and part number

Check the label on your existing battery for one of the listed OEM references such as 5B10V25236, 5B10V25238, L19M3PF9 or SB10V25242. Confirm the laptop chassis matches ThinkBook 14-IML 20RV, 14-IIL 20SL, 15-IML 20RW, 15-IIL 20SM or 15 G2 ARE 20VG. The connector and screw positions must align with the original 3-cell layout. Buyers with other ThinkBook series or different voltage requirements cannot use this pack.

Black 3-cell pack with safety certifications

The black housing matches the factory colour and fits the internal battery bay without modification. Each unit is tested for correct voltage, circuit protection, stable current and low self-discharge before shipping. CE, FCC and RoHS markings confirm compliance with electrical safety and environmental standards. The 3-cell format keeps the profile slim for the ThinkBook 14 and 15 chassis. Users who need higher capacity or a different cell count should look elsewhere.

Questions about this item

Does the battery arrive ready to install in a ThinkBook 14-IML or do I need extra tools?

The GreenTechLLC unit is a direct replacement for the original 3-cell lithium-ion pack and fits the ThinkBook 14-IML, 14-IIL, 15-IML and 15-IIL chassis without additional hardware.

All the listed part numbers show 11.1 V and 4140 mAh — is there any capacity difference between them?

Every compatible part number from 5B10V25237 through SB10X55573 shares the same 11.1 V, 4140 mAh, 45 Wh specification, so runtime is identical regardless of which OEM code your laptop originally used.

What does the 45 Wh rating mean for daily use on a ThinkBook 15-IIL?

At 11.1 V and 4140 mAh the pack stores 45 Wh, which typically delivers several hours of mixed office work on a ThinkBook 15-IIL before needing a recharge.
