Ideal for HP Owners Needing Direct Replacement

Voltage and Part-Number Match Decide Fit

The single specification that determines compatibility is the 11.55V rating combined with the listed HP part numbers. If your original battery shows one of those codes and the same voltage, this unit will fit. If either value differs, the battery will not work in your device.
