Replacement for Presario CQ and Pavilion DV

This 6-cell lithium-ion battery replaces original packs in Compaq Presario CQ and HP Pavilion DV series notebooks. It delivers 10.8V and 4400 mAh capacity for everyday mobile computing. The pack is built to match OEM specifications for direct fit and function. Buyers who need a higher-capacity 9-cell option cannot use this unit.

Sustained discharge and thermal behaviour

The integrated smart control chip manages charging current and discharge rate to keep output steady during long work sessions. Built-in protections guard against short circuit, overheating and overload conditions. These circuits help maintain consistent voltage under continuous load rather than only in short bursts. Users who require hot-swap capability without shutdown will not find that feature here.

Mechanical fit and daily handling

The black 6-cell housing follows the original form factor for the listed Presario, Pavilion, G-series and HDX models. It locks into the existing battery bay using the laptop's native latch mechanism. No extra cables or adapters are needed for installation. Owners of ultra-thin models with internal-only batteries cannot install this pack.

Questions about this item

How much heat does the 10.8V 4400mAh lithium-ion pack generate during extended use?

The 6-cell lithium-ion design runs at standard laptop battery temperatures; the built-in smart chip manages charging current to limit excess heat during all-day operation.

Which original battery part numbers must match for this replacement to fit my Compaq or HP laptop?

Compatible part numbers include HSTNN-IB72, HSTNN-IB79, HSTNN-LB72, HSTNN-Q34C, HSTNN-Q37C, HSTNN-Q40C and HSTNN-Q58C.

Will the 10.8V output work safely with an older HP Pavilion DV4 or DV5 that originally shipped with a 10.8V battery?

Yes — the 10.8V rating matches the original specification for those models, and the onboard protection circuit guards against over-voltage and short circuits.
