Dr. Battery MPL08257P-09 6-cell 10.8V 4400mAh laptop battery

Replacement Battery for HP Envy DV6 and DV7 Series

This Dr. Battery MPL08257P-09 is a new 6-cell lithium-ion pack rated at 10.8V and 4400mAh. It is built as a direct replacement for a long list of HP Envy DV4, DV6, DV7 and M6 models including the DV6-7200 and DV7-7200 families. The black casing matches the original form factor so it fits the existing battery bay without modification. Buyers who need a higher-capacity 9-cell unit or a different voltage should look elsewhere.

Installation and Common Pitfalls

The battery slides into the standard compartment on the bottom of the compatible HP Envy notebooks and locks with the existing latches; no tools are required. A built-in smart control chip manages charging, short-circuit, overheat and overload protection automatically. The most frequent issue is ordering the wrong part: the supplier stresses verifying the exact laptop model, the original battery part number and the 10.8V output before purchase. Skipping that check leads to returns for incompatibility rather than defects.

Capacity and Voltage Determine Fit

The single specification that decides whether this is the correct part is the 10.8V 4400mAh (48Wh) rating combined with the 6-cell lithium-ion chemistry. Only HP Envy models designed for that exact voltage and cell count will charge and report capacity correctly. If the original battery shows a different voltage or a 9-cell 10.8V 7200mAh configuration, this pack will not work properly.
