Direct replacement for HP Pavilion batteries
This new FOCUSTEC lithium-ion battery carries the HT03XL designation and supplies 11.55V from three cells with a rated capacity of 41.7Wh or 3470mAh. It matches part numbers HSTNN-DB8R, HSTNN-LB8L, HSTNN-LB8M, HSTNN-IB8OL, L11119-855 and L11421-1C1. The unit is built as a drop-in replacement for the original pack.
Check your exact model
Confirm that your HP Pavilion belongs to the 14-CE, 14-CF, 14-CK, 14-cm, 14-DF, 14-MA, 14Q-CS, 14Q-CY, 14S-CF, 14S-CR, 15-CS, 15-CW, 15-DA, 15-DB, 15G-DR, 15T-DA, 15T-DB, 17-by or 17-CA series families. Verify the current battery label shows one of the listed part numbers such as L11119-855 or HSTNN-LB8M. Ensure the laptop uses a 3-cell 11.55V pack rather than a different voltage or cell count.
Replaces worn or failed original packs in the same
Swapping to this battery restores full runtime when the original HT03XL no longer holds charge or shows reduced capacity. The upgrade is worthwhile when the existing pack delivers significantly less than the rated 41.7Wh, when the laptop shuts down unexpectedly, or when the system reports a battery health warning. It is not for users needing higher capacity than the original specification, different voltage, or compatibility with models outside the listed Pavilion ranges.
