⚠️ IMPORTANT BUYING NOTICE:

• LA04 Cylindrical External Layout Blueprint: This professional-grade 14.80V Lithium-Ion (Li-ion) external replacement battery features a stick-profile barrel casing layout measuring exactly 273.94 x 33.25 x 22.30 mm and weighing 300.00 g. Unlike flat internal lithium-polymer ribbons trapped deep inside contemporary device casings, this module slides smoothly into the rear external docking tracks of your notebook's outer framework and locks instantly into position using dual spring-loaded chassis slider toggles.

• Model Generation & Platform Verification (Crucial Rule): This custom power module is engineered to bridge an extensive family of early touchscreen and standard mainstream laptops, specifically covering the 2013–2014 HP Pavilion 14 Notebook PC series, Pavilion 15 Notebook PC series, Pavilion TouchSmart 14 Series, and Pavilion TouchSmart 15 Series. Please note that it will not fit later redesigned iterations (such as the Pavilion 14-ab, 14-al, 15-ab, 15-au, or 15-cc lines), which utilize completely internal thin-profile lithium ribbon designs and lower voltage parameters. Before placing your checkout order, slide your laptop's physical locking levers open, release the old battery pack, and verify that its casing explicitly displays core tracking markers like LA04, LA04041DF, HSTNN-UB5M, HSTNN-UB5N, or 728460-001.
