Black six-cell housing with integrated protection

The battery uses a black plastic enclosure that matches the original form factor for direct installation. A built-in smart control chip manages charging and discharging while providing short-circuit, overheat and overload safeguards. No additional cables or adapters are required for daily use.

Limited to 10.8V 4400mAh specification

The pack operates at a fixed 10.8V output and cannot support laptops that require a different voltage or higher capacity. Runtime will vary with system load and battery age. Buyers needing extended runtime beyond 4400mAh or a different voltage must select another model.

Questions about this item

What voltage does the 10.8 V lithium-ion pack deliver to compatible HP and Compaq laptops?

It supplies a steady 10.8 V at 4400 mAh, matching the original specification for the listed Pavilion, HDX, G-series and Presario models.

Which battery bay dimensions and latch style does the 6-cell pack fit?

The black 6-cell housing is moulded to the OEM footprint for HP part numbers HSTNN-Q34C, Q37C, Q40C, Q58C, UB72, UB73 and W50C, so it slides into the same bay without adapters.

What is the correct first-use procedure for the built-in smart chip?

After inserting the pack, charge it fully without interruption, then run the laptop on battery until it shuts down; this single cycle calibrates the protection circuitry.
