Dr. Battery MPL08257P-17 6-cell 4400 mAh 10.8 V laptop battery

Replacement battery for HP Envy DV6 and DV7 series

The Dr. Battery MPL08257P-17 is a 6-cell lithium-ion unit built to match the original equipment specification for a wide range of HP Envy DV6-7200 and DV7-7200 laptops. It delivers 10.8 V and 4400 mAh for 48 Wh of capacity. The pack includes a smart control chip that manages charging, discharge and safety protections against short circuit, overheat and overload.

Practical limits of a 10.8 V 6-cell lithium-ion pack

Voltage is fixed at 10.8 V, so the battery will only work in machines designed for that exact potential. Capacity of 4400 mAh sets the maximum runtime available from a single charge. The six-cell construction determines the physical envelope; the pack will not fit bays designed for 4-cell or 9-cell units. The integrated protection circuit prevents unsafe operation but cannot increase the energy stored.

Match your original battery part number before

Compatibility is confirmed only by comparing the original part number — such as HSTNN-LB3N, HSTNN-LB3P or HSTNN-OB3N — and the output voltage printed on the old pack. The supplier lists dozens of Envy and M-series models, but sub-models within those families may use different batteries. Verifying the original part number is the single step that decides whether this unit will fit and function correctly.
