Replacement for HP and Compaq notebooks
The Dr. Battery MPL08217P-11 is a 6-cell lithium-ion pack rated at 10.8V and 4400 mAh. It fits a wide range of HP G50, G60, G70, HDX 16 and Pavilion DV4, DV5, DV6 series machines. Compaq Presario CQ40, CQ50, CQ60 and CQ70 models are also supported. The unit ships new with a one-year warranty.
Steps up from worn original cells
This pack replaces OEM part numbers such as HSTNN-UB72, HSTNN-UB73, HSTNN-W50C, HSTNN-W51C, HSTNN-W52C, HSTNN-XB72, HSTNN-YB72 and 462889-121. The jump is worth it when the original battery no longer holds a useful charge or shows swelling. A built-in smart control chip manages quicker charging, lower power consumption and longer discharge time. Buyers who need a higher capacity than 4400 mAh cannot be served by this model.
Steady output with safety guards
Under sustained load the smart control chip regulates current to prevent short circuit, overheat and overload conditions. The lithium-ion chemistry delivers stable voltage across the discharge curve rather than a brief peak. Cells are tested to meet OEM specification levels for reliable performance during extended sessions.

Questions about this item
Does this 6-cell 10.8V pack fit the HP G71t or HDX 16 battery bay?
The battery is listed as a direct replacement for HP G71t, HDX 16, HDX 16T and the HSTNN-UB72, HSTNN-UB73, HSTNN-W50C, HSTNN-W51C, HSTNN-W52C, HSTNN-XB72, HSTNN-YB72 and 462889-121 part numbers.
What is the correct way to insert the pack and the step users often miss?
Align the pack with the bay rails, slide it in until the latch clicks, then lock the external release switch; the step often missed is failing to engage the lock after the click.
When should the 4400 mAh unit be replaced?
Replace the pack when run-time drops well below the original 48Wh rating or the smart chip reports a permanent capacity loss after a full charge cycle.
