Fits HP Envy DV4-5200 DV6-7200 and DV7-7200 series

This battery slots into the existing compartment on compatible HP Envy notebooks without requiring adapter cables or firmware updates. It replaces OEM part numbers such as 671731-001, 672326-421, 672412-001 and H2L55AA. The integrated protection circuitry frees the system from external power-management accessories. Installation follows the standard battery-release procedure documented by the laptop manufacturer.

Suits owners of listed Envy models needing a fresh

Buyers with an HP Envy DV4-5200, DV6-7200, DV7-7200 or compatible M-series machine can restore mobile runtime with this unit. It is not for users whose laptop model or original battery part number falls outside the supplied compatibility list. Shoppers requiring a higher-capacity 9-cell option or a different voltage should look elsewhere. Always verify the original battery label before ordering.
