Replacement for Dell Latitude and Precision
This Dr. Battery MPL05222P-T01 is a new 6-cell lithium-ion pack rated at 11.1V and 4400mAh. It replaces original Dell batteries such as 4M529, KY265, NM631, PP27L, PT434, PT653 and W1193. The unit suits owners of Latitude 6400 ATG, E6400, E6400 XFR, E6410, E6500, E6510 and Precision M4400 or M4500 models.
Fits directly into the existing battery bay
No extra cabling, mounting hardware or firmware updates are required; the pack uses the same connector and physical footprint as the original Dell unit. A built-in smart control chip manages charging and discharging cycles while providing short-circuit, overheat and overload protection. The design frees the user from carrying an external power bank for typical mobile workloads.
Runs at the standard 11.1V with a 49Wh capacity
Under normal office use the pack delivers consistent voltage without excessive heat buildup. The lithium-ion chemistry and protection circuitry keep noise at zero because there are no moving parts. Power draw follows the laptop's own demand profile, so the battery does not impose additional thermal load on the system.
