Replacement battery for HP Pavilion and Presario

This lithium-ion battery replaces the HP MU06 and MU09 packs used in Pavilion G4, G6, G7 and DM4 models as well as Presario CQ42, CQ56, CQ57 and CQ62 notebooks. It is a new component for owners of those specific laptops who need a direct substitute for the original power pack. Buyers with other HP series or non-HP machines cannot use this part.

Safety certifications and protection circuits

The cell carries UL, CE, FCC and RoHS certifications and includes overheat, short-circuit and overload protection circuits. These safeguards operate during both use and storage to limit thermal and electrical risk. No acoustic or power-draw figures are supplied for the battery itself.

Expected runtime of 2 to 2.5 hours

Typical operation time is quoted at 2 to 2.5 hours and will vary with the host device and workload. This single figure determines whether the pack meets a user’s mobility needs; no capacity in milliampere-hours or voltage is provided.

Questions about this item

How do I install the FOCUSTEC MU06 battery in my HP Pavilion G6 and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch to unlock the old pack, lift it out, align the new MU06 contacts with the bay, press firmly until the latch clicks, then charge fully before first use — skipping the full initial charge is the step most users miss.

What maintenance or replacement will the MU06 lithium-ion pack need later?

The MU06 is a sealed lithium-ion unit with no user-serviceable parts; expect gradual capacity loss after several hundred cycles, at which point the entire battery must be replaced — no cell-level servicing is possible.

What limit appears first during sustained use of this MU06 battery?

The expected operation time of 2-2.5 hours per charge is the first practical limit; actual runtime varies with device type and workload, and the pack will eventually require more frequent recharging as capacity ages.
