Ready-to-install replacement battery

This 3-cell lithium-ion pack delivers 11.4 volts and 24 watt-hours of capacity. It matches the form factor and connector of the original Lenovo units used across the ThinkPad X240, X250, X260 and X270 families as well as the T440 and T440s lines. Buyers who need a higher-capacity 6-cell design or a battery for the T460s, T470 or T470s models cannot use this part.

Low thermal impact under normal loads

The cell chemistry runs cool during typical office workloads and light web browsing, adding no audible fan noise to the system. Power draw stays within the original design envelope, so the laptop’s existing thermal solution handles the load without extra stress. No special cooling or configuration changes are required after installation.

Direct-fit mechanical compatibility

The pack aligns with the original screw holes and latch mechanism, so no tools beyond a screwdriver are needed for the swap. Firmware recognises the battery immediately, restoring full charge reporting and power-management features. No driver discs, calibration utilities or proprietary software bundles are included or required.

Questions about this item

How do I install this 3-cell 11.4 V battery in a ThinkPad X250, and what step is often missed?

Power off the laptop, remove the external pack first, then slide this internal battery in until the latch clicks; the step often missed is re-enabling the internal battery in BIOS after the swap.

What maintenance or replacement will this 24 Wh Li-ion pack need later?

Capacity fades with each charge cycle; plan to replace the pack when runtime no longer meets your workload — no user-serviceable cells inside.

What limit appears first on this 11.4 V battery during sustained heavy use?

The 24 Wh capacity is the limiting factor — runtime drops quickly under continuous high drain before thermal throttling becomes an issue.
