Dr. Battery MPL08255P-21 replacement
This 6-cell lithium-ion pack delivers 10.8V and 4400 mAh for compatible HP and Compaq notebooks. It fits models such as EliteBook 6930p, 8440p and 8440w Mobile as well as Pavilion dm1 series laptops. Buyers needing a different voltage or a higher capacity pack will not be served by this unit.
Thermals noise and power draw
The integrated smart control chip manages charging current to reduce heat during normal operation. Overheat, short-circuit and overload protections keep the cell temperature stable under typical workloads. No active cooling is required because the battery is a passive component.
Bundled protections and warranty
Built-in safeguards extend discharge time and lower power consumption compared with cells lacking such circuitry. A one-year manufacturer warranty covers defects in materials and workmanship. No software utilities or extra accessories are included in the package.

Questions about this item
How do I install the Dr. Battery MPL08255P-21 6-cell 10.8V 4400mAh laptop battery, and what step do people often miss?
Slide the new pack into the compartment until the release latches click securely; the step many skip is confirming the original part number matches 646757-001, A2Q96AA, HSTNN-DB3B, HSTNN-LB3A, HSTNN-LB3B or HSTNN-YB3A before fitting.
What maintenance or replacement will this 6-cell lithium-ion 4400mAh pack need later?
Lithium-ion cells degrade with charge cycles; expect reduced run-time after several hundred cycles and plan to replace the pack when it no longer holds a useful charge for your HP Pavilion dm1-4110, dm1-4120, dm1-4150, dm1-4170, dm1-4190 or compatible models.
What limit appears first on this 10.8V 48Wh battery during sustained heavy use?
The 4400mAh capacity sets the total energy available; under continuous high load the pack will reach its discharge limit sooner than lower-draw scenarios, triggering the built-in protection circuit to shut down output.
