Replacement Battery for HP Pavilion 14-AL Series

This 11.55V 41.5Wh lithium-ion battery replaces part numbers SE03XL, HSTNN-LB7G, HSTNN-UB6Z, 849568-421, 849568-541 and 849908-850. It fits HP Pavilion 14 models including 14-AL000, 14-AL125TX, 14-AL136TX and the 14-AL027TX through 14-AL007NG variants. The pack uses Grade A cells and carries CE certification.

Upgrade from a Depleted or Failing Original Pack

The jump is worth it when the original battery no longer holds a useful charge, reports a permanent fault or physically swells. A fresh 3615mAh cell restores the runtime the laptop delivered when new. It does not increase capacity beyond the factory 41.5Wh specification, so buyers who want more storage or longer life than the original design cannot get it here.

Verify Model, Connector

Check the laptop model via Windows System Information (msinfo32) or the label on the chassis. Remove the back cover to confirm the existing battery carries one of the listed part numbers. Compare the connector position and cable length (long or short) against the product image to ensure physical compatibility.
