Replacement battery for ThinkPad X131e series

The Dr. Battery MPL10244P-07 is a six-cell lithium-ion pack rated at 11.1V and 4400 mAh, built to match the original specifications for Lenovo ThinkPad X121e, X130e, X131e and X140e models. It suits owners of those machines who need a new power source that meets the OEM voltage and capacity figures.

Simple swap with built-in safety chip

The pack installs by releasing the original battery latch and sliding the replacement into the same bay, a process that normally takes under a minute. A smart control chip handles charging current and provides short-circuit, overheat and overload protection, reducing the risk of damage if the pack is seated incorrectly or the connector is misaligned.

Steady output during long sessions

Rated at 49 Wh, the cell chemistry is designed to deliver consistent voltage across extended discharge cycles rather than only in short bursts. The protection circuitry maintains stable output while the laptop draws continuous load, helping to avoid sudden shutdowns when the remaining charge drops low.
