Compatible HP models

This replacement battery fits a wide range of HP Pavilion x360 convertibles and standard Pavilion notebooks, including 14‑inch, 15‑inch and 17‑inch series. It also covers several HP 240, 245, 250, 255, 340, 348 and 470 G5‑G7 models. The cell matches original part numbers such as L11119‑855, HT03XL and TF03XL for a direct swap.

Buyers needing other voltages or capacities

The pack delivers 11.55 V and 41.9 Wh from three lithium‑ion cells, so it suits only devices designed for that exact voltage and energy rating. Laptops requiring a different cell count, voltage or watt‑hour value will not operate correctly with this unit. Customers with those requirements should look for a battery specified for their machine.

41.9 Wh capacity and 11.55 V output

The 41.9 Wh rating determines how long the notebook can run on a full charge, while the 11.55 V output must match the system’s power rail. Verifying both figures against the original battery label confirms whether this TF03XL pack is the correct replacement for a given HP laptop.

Questions about this item

Will the TF03XL fit my HP Pavilion x360 15-cc series without modification?

The TF03XL matches the original 1:1 dimensions for HP Pavilion x360 15-cc, 14-ce, 14-cf, 14-ck, 14-cm, 14-df, 14-ma and 17-ar models listed.

Which connector do I attach first when installing the TF03XL, and what is the common mistake?

Disconnect the old pack, align the TF03XL multi-pin connector, press straight in until it clicks; the common mistake is forcing it at an angle and bending pins.

How long before the 41.9 Wh TF03XL typically needs replacing?

A Li-ion pack of this capacity normally delivers several years of daily cycling; replace when run-time falls below your needs.
