HT03XL 41.7 Wh replacement battery

This lithium-ion pack delivers 3470 mAh at 11.55 V across three cells and is built to match the electrical profile of the original HT03XL and L11119-855 units. It fits a wide range of HP Pavilion 14, 15 and 17 series notebooks, including 15-CS, 15-DA, 15-DB, 15-DW, 15-DY, 17-BY and 17-CA families. The unit is new and ready for immediate installation.

Li-ion chemistry and fixed voltage

The 11.55 V output is set by the three-cell Li-ion design, so the battery only works in laptops that expect this exact voltage and connector layout. Capacity is limited to 41.7 Wh, which defines the maximum runtime available from a single charge. Systems requiring a different cell count, voltage or physical form factor cannot use this pack.

Replaces worn HT03XL and L11119-855 units

Swapping a depleted original restores full mobile operation without changing the charger or power-management settings. The upgrade is worthwhile when the existing battery no longer holds a useful charge or shuts down under load. It does not add capacity beyond the factory 41.7 Wh specification, so users needing longer unplugged time must look elsewhere.

Questions about this item

Should I pick the 3470 mAh or 41.7 Wh version?

Both figures describe the same HT03XL battery; 3470 mAh at 11.55 V equals 41.7 Wh, so there is no separate capacity option to choose.

What does the 41.7 Wh rating deliver in daily use?

The 41.7 Wh capacity powers compatible HP Pavilion notebooks for typical mixed workloads, matching the original OEM energy specification.

Does the 11.55 V output limit which Pavilion models I can use it in?

The 11.55 V, 3-cell Li-ion design matches the voltage requirement of all listed Pavilion 14, 15 and 17 series models.
