Replacement battery for Dell Latitude and Precision
The Dr. Battery MPL05222P-10 is a new 6-cell lithium-ion pack rated at 11.1V and 4400 mAh. It matches the original specifications for Dell Latitude E6400, E6410, E6500, E6510 and E8400 models as well as Precision M2400, M4400 and M4500 workstations. Buyers who need a different voltage or a higher cell count will not be served by this unit.
Practical limits of a 6-cell 11.1 V lithium-ion pack
The battery delivers 49 Wh through the laptop's native connector and relies on the system's own charging circuitry. It includes short-circuit, overheat and overload protection managed by an internal smart control chip. Runtime will vary with workload, screen brightness and power-management settings, so exact hours cannot be guaranteed.
Capacity and headroom for mobile workloads
At 4400 mAh the pack supports typical office tasks, web browsing and light content creation on compatible Dell machines. Heavier loads such as sustained rendering or discrete GPU compute will draw the reserve down more quickly. Users who regularly work away from mains power for a full day may need to carry a second charged pack.
