Dr. Battery MPL05222P-23 replacement laptop battery
This 6-cell lithium-ion unit delivers 4400 mAh at 11.1 V for compatible Dell Latitude and Precision models. It targets owners of E6400, E6410, E6500, E6510, E8400, M2400 and M4400 systems who need a direct swap for an ageing pack. Buyers whose laptops use a different form factor or voltage cannot use this battery.
Sustained discharge and smart-chip management
The built-in control chip regulates charging current to reduce heat buildup during long sessions and extends usable discharge time compared with unmanaged cells. Protection circuits cut power on short-circuit, overheat or overload events, keeping output stable under continuous load rather than only in short bursts. Capacity is rated at 49 Wh for consistent runtime.
Thermals, noise and power draw in normal use
As a solid-state power source the battery produces no audible noise and adds no active cooling requirement to the chassis. Internal resistance stays low during typical office workloads, so surface temperature remains close to ambient and the host laptop's fan profile is unchanged. The pack draws only the energy the system requests, with no parasitic overhead.

Questions about this item
Does the 11.1 V 4400 mAh battery run hot or drain quickly when the laptop is used all day?
The 6-cell lithium-ion pack is rated at 49 Wh and includes a smart control chip that manages charging and discharge to limit heat buildup during extended use.
What must I already have in the laptop for this MPL05222P-23 to fit and work?
The battery replaces Dell part numbers such as 451-10583, 4M529, 4N369, 9H626, C719R, DFNCH, FU268, FU272 and FU274, so the laptop must use one of those original batteries.
Will this 6-cell 11.1 V pack work in an older Dell Precision M2400 that I keep as a backup machine?
Yes, the compatibility list covers Precision M2400, M4400 and M4500 workstations alongside the Latitude E6400, E6410, E6500 and E6510 series.
