Replacement Battery For HP Pavilion 14

This KingSener SE03XL lithium-ion cell delivers 41.5Wh at 11.55V and replaces part numbers HSTNN-LB7G, HSTNN-UB6Z, TPN-Q171, 849568-541, 849908-850 and 849568-421. It fits HP Pavilion 14-AL series laptops including models AL028TX, AL029TX, AL127TX, AL107NE and AL102TX. The unit ships new in black.

Steady Capacity Through Full Discharge

The 41.5Wh rating reflects usable energy across a complete charge cycle rather than a brief peak. Lithium-ion chemistry maintains consistent voltage output while the notebook draws power for typical productivity tasks. Cell quality is backed by a two-year replacement guarantee from the manufacturer.

Verify Part Number Before Ordering

Match the original battery label to one of the listed part numbers such as SE03XL, HSTNN-LB7G or TPN-Q171 to confirm compatibility. Ensure the laptop model appears in the supported Pavilion 14-AL series list provided. No other specifications are required for installation.

Questions about this item

Does the 11.55 V lithium-ion pack run hot or draw extra power during all-day use?

The 41.5 Wh lithium-ion cell operates at its rated 11.55 V without additional power draw; normal charging and discharging produce only typical warmth for a replacement battery of this capacity.

Must my HP Pavilion 14 already have the HSTNN-LB7G or TPN-Q171 part installed for this SE03XL to fit?

Yes — the SE03XL directly replaces part numbers HSTNN-LB7G, HSTNN-UB6Z, TPN-Q171, 849568-541, 849908-850 and 849568-421, so one of those must be the original battery in the laptop.

Will the SE03XL work in an older Pavilion 14-AL003TU that currently uses the 849568-421 battery?

The SE03XL lists 849568-421 among its replaceable part numbers and supports the Pavilion 14-AL003TU, so it will function as a direct swap for that older unit.
