Replacement battery for Dell Latitude and Precision
The Dr. Battery MPL05222P-06 is a new 6-cell lithium-ion pack rated at 11.1V and 4400 mAh. It replaces original Dell batteries such as FU274, FU439, NM631, KY265, PT434, W1193 and 1M215. The grey housing fits Latitude E6400, E6410, E6500, E6510, E8400 and Precision M2400, M4400, M4500 workstations. Buyers needing a different voltage or form factor cannot use this unit.
Smart control chip with protection circuits
A built-in smart control chip manages charging and discharge to deliver quicker charging, lower power consumption and longer run time. The chip also enables short-circuit, overheat and overload protections for safer operation. No software bundle or additional accessories are included in the package.
49 Wh capacity for typical mobile workloads
The 49 Wh rating supports everyday office tasks, web browsing and video playback on compatible Dell laptops. Runtime will vary with screen brightness, CPU load and battery age. Heavy workloads such as sustained rendering or gaming will deplete the charge faster, and users requiring all-day operation without recharging should consider a higher-capacity alternative.

Questions about this item
How many charge cycles will the 6-cell lithium-ion pack handle before it needs replacing?
The built-in smart control chip manages charging to extend usable life, and the one-year warranty covers defects in materials or workmanship during that period.
What is the first limit reached during continuous heavy load on the 4400 mAh battery?
The 49 Wh capacity determines runtime; sustained high draw will deplete the charge before any thermal or voltage threshold is hit.
Does the 11.1 V pack run hot or make noise when the laptop is on all day?
The lithium-ion cells and protection circuitry operate silently; normal warmth occurs during charge or discharge, but no fan or moving parts are present.
