Replacement battery for HP Pavilion 15 series

The LXHY LA04 is a 41 Wh lithium-ion pack built to fit HP Pavilion 15-AU, 15-AW and 15T-AW models. It targets owners whose original cell no longer holds a useful charge and who want a direct swap without adapter cables.

Installation experience and common issues

Two screwdrivers are included so the bottom case can be opened and the old pack removed in minutes. The connector matches the motherboard header exactly, but the battery must be disconnected before the first boot or the system may not recognise the new capacity.

Capacity and realistic runtime

At 41 Wh the pack delivers several hours of typical office work or video playback on a healthy platform. Heavy multi-core loads or high screen brightness will drain it faster, and the four-cell design cannot match the endurance of higher-capacity six-cell alternatives.
