Compatible ThinkPad models

This replacement battery fits the Lenovo ThinkPad X121e, X130e, X131e and X140e series, including the X130e 2340 and X140e 20BL000BUS variants. It matches FRU part numbers 42T4943, 42T4945, 42T4949, 42T4951 and 42T4961. Buyers with other ThinkPad lines or non-Lenovo laptops cannot use this unit.

6-cell 11.1 V lithium-ion pack

The battery uses a six-cell lithium-ion chemistry rated at 11.1 volts. This voltage and cell count are the single specification that determines whether the pack will be recognised and charged correctly by the supported ThinkPad models. A different voltage or cell configuration will not work.

4400 mAh capacity with 49 Wh energy

The 4400 mAh rating provides 49 watt-hours of energy for typical office workloads and web browsing on the compatible X-series chassis. Runtime decreases under sustained heavy loads or when the pack ages beyond its design life. Users needing significantly longer unplugged time will find the capacity insufficient.

Questions about this item

How long will the 4400 mAh capacity actually run a ThinkPad X131e?

The 49 Wh pack typically delivers several hours of mixed office work on an X131e, though exact runtime varies with screen brightness, CPU load and battery age.

Does the 11.1 V output match the original Lenovo FRU 42T4961 specification?

Yes, 11.1 V is the exact nominal voltage listed for FRU 42T4961 and the other compatible part numbers.

Will the 6-cell black casing fit the battery bay on an X140e 20BL000BUS without modification?

The pack is moulded to the same footprint as the original 6-cell Lenovo batteries, so it seats and locks in the X140e bay directly.
