HP and Compaq Battery Part Number Identification

HP and Compaq batteries are often identified by a white barcode sticker. The most useful codes may appear as Replace with HP spare, a six digit code plus dash and three digits, an HSTNN code, or a short battery model such as MU06 or KI04.

Quick steps

1. Turn off the laptop and disconnect the power adapter.
2. Remove the battery if removable, then inspect the white barcode sticker and rating label.
3. Look for Replace with HP spare, Spare, HSTNN, Model or P/N.
4. Record the complete number exactly, including dashes.
5. Search by the HP spare number or HSTNN code, then compare voltage, shape, connector and compatible model list.

Compatibility tip: HP batteries can show several numbers on the same label. The HP spare number and HSTNN code are both useful for cross-reference searches.
