Replacement battery for Dell Latitude and Precision
The Dr. Battery MPL05222P-09 is a new 6 cell lithium-ion pack rated at 11.1V and 4400 mAh. It replaces Dell part numbers including DFNCH, FU268, FU272, FU274, FU439, NM631, KY265, PT434 and W1193. Compatible models span Latitude 6400 ATG, E6400, E6400 XFR, E6400 ATG, E6410, E6410 ATG, E6500, E6510 and E8400 as well as Precision M2400, M4400 and M4500 workstations. Buyers who need a different voltage or cell count cannot use this pack.
Thermals noise and power draw in normal use
The integrated smart control chip manages charging to reduce power consumption and extend discharge time. Built-in safeguards protect against short circuit, overheat and overload conditions during operation. No active cooling components are present so the battery runs silently. Users who require detailed thermal metrics or acoustic ratings will not find them in the specifications.
What the bundled accessories
The package contains only the battery unit itself; no installation tools, cables or software discs are included. Dr. Battery provides online resources such as a website and YouTube channel for fitting guidance. The manufacturer backs the product with a one year warranty from 2020. Customers who expect a hardware kit or proprietary management application will not receive either.

Questions about this item
How do I install the MPL05222P-09 in my Dell Latitude E6410 and what step is often missed?
Power off the laptop, disconnect the AC adapter, slide the release latch, remove the old pack, insert the new 6-cell unit until it clicks, then lock the latch; the step often missed is re-engaging the latch fully so the battery seats on all contacts.
What maintenance or replacement will this 11.1V 4400mAh lithium-ion pack need later?
The pack uses six lithium-ion cells rated at 49Wh; capacity will gradually fade with charge cycles, so plan to replace the battery when runtime no longer meets your needs.
What limit appears first during sustained use of this 6-cell replacement battery?
The 4400mAh capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or voltage protection triggers.
