Replacement Battery for HP Pavilion Series

The LXHY LA04 is a new 11.55 V laptop battery built to replace original HP units across a wide range of Pavilion 14, 15 and 17 inch models. It matches the electrical specification of the HT03XL and HSTNN-UB7J packs used in many current notebooks. Install it to restore mobile power without adapting cables or connectors.

Sustained Operation and Capacity

Rated at 41.7 Wh, the cell pack delivers consistent energy during long work sessions rather than only brief bursts. The chemistry maintains stable voltage through the discharge curve so the system does not throttle unexpectedly under load. Cycle life meets the standard expectation for daily charge and discharge routines.

Voltage Match Decides Fit

The single specification that confirms compatibility is the 11.55 V nominal output; a different voltage will prevent the laptop from recognising the pack or cause charging errors. Verify that your original battery carries one of the listed part numbers such as L11421-422 or HT03XL before ordering.

What must already be in the laptop for this LA04 pack to work?

The laptop must use one of the listed HP part numbers such as HT03XL, L11421-422, HSTNN-UB7J or any of the other compatible P/Ns and belong to the supported Pavilion 14, 15, 17 or x360 series.

Will the LA04 battery fit an older HP Pavilion 15-CS model that originally used a 41 Wh pack?
