Replacement battery for ThinkPad X131e and X140e
This 6-cell lithium-ion pack is built as a direct replacement for multiple Lenovo ThinkPad models including the X121e, X130e, X131e and X140e series. It matches the original 11.1V specification and 4400mAh capacity to restore factory runtime. The unit is new and carries a one-year warranty from the manufacturer.
Practical limits of the 11.1V lithium-ion standard
The chemistry delivers a nominal 11.1V across six cells, which fixes the energy ceiling at 49Wh for this capacity class. Voltage drops as the pack discharges, so sustained loads near the current limit will reduce usable runtime. The integrated protection circuit stops charging at the safety threshold and cuts output on short circuit, overheat or overload events.
4400mAh capacity and typical headroom
A 49Wh pack of this size typically powers a compatible ThinkPad through several hours of light office work or video playback. Heavy multi-core workloads, maximum screen brightness or attached peripherals will drain it faster. The smart control chip optimises charge cycles for longer service life, but the physical cell count means the pack cannot match higher-capacity 9-cell alternatives.

Questions about this item
Which capacity should I choose for my ThinkPad X131e?
This pack provides 4400 mAh at 11.1 V, giving 49 Wh of energy.
How long will 49 Wh last in daily use?
Runtime depends on the laptop's power draw; a typical ThinkPad X131e consumes 10–20 W, so expect roughly 2.5–5 hours per charge.
What connector and voltage does the battery use?
It matches the original Lenovo 11.1 V interface used by part numbers such as 42T4943, 42T4945, 42T4949 and 42T4951.
