Compatible HP models

This replacement battery fits HP Pavilion DV7 series and HP HDX 18 notebooks. It matches original part numbers including HSTNN-IB75, HSTNN-OB74, HSTNN-OB75, HSTNN-Q35C, HSTNN-XB75 and KS525AA. The unit is built for owners of those specific models who need a new power source.

Installation and common issues

The pack slots into the standard battery bay on the listed laptops without tools. Most problems arise when buyers order without confirming their exact model number or original battery voltage. A mismatched part will not seat correctly or will fail to charge.

Practical limits of the 14.4 V 4400 mAh design

The 8-cell lithium-ion layout delivers 63 Wh at 14.4 V, which defines the run time ceiling for this form factor. Capacity cannot be increased without changing the physical size or voltage, so users needing longer unplugged sessions must carry a spare pack.

Questions about this item

How do I confirm the 4400 mAh capacity is delivering the expected run time after installation?

The battery uses 8 lithium-ion cells rated at 14.4 V and 63 Wh; compare the reported full-charge capacity in your OS power utility with the 4400 mAh figure to verify it is working as intended.

What comes in the package and do I need any extra cables or tools?

The box contains the 8-cell replacement battery only; no additional cables, screws or tools are included so nothing else must be bought separately for the swap.

My original battery is labelled HSTNN-OB75 — is this MPL08218P-08 the correct version?

Yes, the MPL08218P-08 lists HSTNN-OB75 among its compatible part numbers along with HSTNN-IB75, HSTNN-OB74, HSTNN-Q35C and HSTNN-XB75, so it matches your original.
