Compatible HP Laptop Battery

This 9-cell lithium-ion battery replaces the HP MU09 and MU06 packs used in Pavilion DV6, DV7, DM4, G4, G6, G7, G42, G56 and G62 series notebooks. It is a new, direct-fit spare for part numbers such as 636631-001, 593550-001 and HSTNN-LB0W. The pack is ready to install without adapters or soldering.

Users needing 84 Wh capacity

Owners of the listed HP and Compaq Presario models who want the higher 84 Wh rating will find this unit matches the original MU09 specification. Buyers whose laptop requires the lower 58 Wh MU06 pack should look elsewhere, as the physical profile and connector differ. Systems outside the documented compatibility list are not supported.

84 Wh energy rating

The single figure that decides fit is the 84 Wh capacity, which is distinct from the 58 Wh MU06 variant. Cross-reference your device part number against 636631-001, 593550-001 or the HSTNN codes before ordering.

Questions about this item

Will the 9-cell 84 Wh MU09 battery fit my HP Pavilion dv6-3000?

The MU09 is listed as compatible with the dv6-3000 series; verify your original part number matches 636631-001 or 593550-001 before ordering.

What is the correct way to install the MU09 battery and what step do people often miss?

Power off the laptop, disconnect the AC adapter, slide the release latches, insert the 9-cell pack until it clicks, then charge fully before first use — skipping the initial full charge is the common mistake.

How long will the 7800 mAh MU09 last before it needs replacing?

The 9-cell lithium-ion pack is rated for extended life and delivers more than 5 hours per charge when new; runtime will gradually decrease with age and usage cycles.
