Product Identity

This is a 2-Power CQ42 lithium-ion replacement battery built for a wide range of HP Pavilion, Compaq Presario and HP 2000 series notebooks. It suits owners of compatible G4, G6, G7, DV4, DV6, DV7, DM4 and CQ32 through CQ72 models who need a fresh power source.

Deciding Specification

The pack delivers 10.8 volts with a 5200 milliampere-hour rating and 47 watt-hours of capacity across six cells. Matching this voltage and capacity to the original MU06 or MU09 part number confirms the correct fit for the listed machines.

Sustained Behaviour

Lithium-ion chemistry provides steady output through a full discharge cycle without the voltage sag seen in older chemistries. The 47 watt-hour capacity supports extended mobile work sessions between charges under typical mixed workloads.

Questions about this item

What does the 10.8 volt rating mean once the battery is installed in a laptop?

The 10.8 volt rating matches the original voltage required by compatible HP Pavilion, Compaq Presario and Pavilion DV series notebooks, so the system recognises the pack and charges it normally.

What interface or standard does the pack use, and what does that limit in practice?

The pack uses the proprietary multi-pin connector specified for HP part numbers MU06, MU09, 593553-001 and 593554-001, so it only fits laptops designed for those exact part numbers.

What physical space does the 6-cell pack need to fit or mount in the chassis?

The 6-cell lithium-ion pack measures 14.33 inches wide, 12.83 inches high and 9.06 inches deep, matching the extended battery bay on the listed HP models.
