⚠️ IMPORTANT BUYING NOTICE:

• HS04 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 273.90 x 34.90 x 20.90 mm and weighing 297.20 g. Unlike flat internal lithium-polymer ribbons trapped deep inside device casings, this module slides cleanly 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 entry-level commercial and mainstream consumer laptops, specifically covering the fourth-generation HP 240 G4, 245 G4, 250 G4, and 255 G4 Notebook PCs, alongside HP Pavilion 14-ac, 14-af, 15-ac, and 15-af consumer platforms. Please note that it will not fit G3 or newer G5, G6, or G7 versions of the same model lines, which utilize completely different locking teeth arrangements, structural casing thicknesses, and connection shapes. 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 HS04, HS03, HSTNN-LB6V, HSTNN-LB6U, or 807956-001.
