⚠️ IMPORTANT BUYING NOTICE:

• RI04 Cylindrical External Layout Blueprint: This professional-grade 14.40V Lithium-Ion (Li-ion) external replacement battery features a stick-profile barrel casing layout measuring exactly 275.70 x 34.00 x 20.50 mm and weighing 292.00 g. Unlike flat internal lithium-polymer ribbons, this module slides smoothly into the open rear docking tracks of your notebook's outer framework and locks instantly into position using dual spring-loaded chassis slider toggles.

• Model Generation & Framework Verification (Crucial Rule): This custom power module is engineered to bridge specific third-generation (G3) enterprise workhorses and specialized high-performance consumer laptops, specifically covering the HP ProBook 450 G3, ProBook 455 G3, ProBook 470 G3, and Envy 15-q (such as 15-q001tx) lines. Please note that it will not fit ProBook G0, G1, G2, G4, or newer generation frames, which utilize completely altered locking teeth configurations, structural casing designs, and voltage parameters. Before finalizing your order, slide your laptop's physical locking levers open, release your stock battery pack, and verify that its housing explicitly displays core tracking markers like RI04, RIO4, HSTNN-DB7B, HSTNN-PB6Q, or 805294-001.
