Dr. Battery MPL10244P-23 6-cell 11.1V 4400mAh laptop battery

Dr. Battery 6-Cell 11.1V Replacement

This new 6-cell lithium-ion battery replaces original Lenovo packs for ThinkPad X121e, X130e, X131e and X140e models. It delivers 11.1V and 4400mAh capacity with a built-in smart control chip for managed charging and discharge cycles. The black enclosure matches the original form factor for direct installation.

Upgrade from Degraded or Failed OEM Packs

Swap this unit in when the original battery no longer holds a useful charge or shows reduced runtime under load. The 49Wh rating restores the design capacity these models shipped with, so the improvement is clear whenever the old pack falls short of that baseline. Integrated protection guards against short circuit, overheat and overload during the transition.

4400mAh Capacity for Standard Workloads

The 4400mAh rating supports typical office tasks, web browsing and video playback on compatible ThinkPad chassis. Runtime scales with screen brightness, CPU load and peripheral use, so heavy multitasking or maximum brightness will draw the pack down faster. Users needing all-day operation without mains access should plan for a recharge or a second pack.
