⚠️ IMPORTANT BUYING NOTICE:

• KU533AA / AV08XL External Docking Layout Blueprint: This professional-grade 14.40V Lithium-Ion (Li-ion) external replacement battery features a robust, cylindrical cell casing layout measuring exactly 268.50 x 53.40 x 20.20 mm and weighing 485.60 g. Unlike modern thin internal batteries, this module slides cleanly into the rear external alignment tracks of your notebook and locks securely using dual chassis spring latches.

• Model Generation & Voltage Verification (Crucial Rule): This custom power core is engineered around a high-voltage 14.40V circuit designed specifically for early-generation high-performance HP enterprise laptops and graphics-heavy mobile workstations. It will not fit or work with later, slim-profile EliteBook platforms (such as the EliteBook 850 G1 or newer series), which run on completely flat internal layouts with lower voltages. Before placing your order, slide your laptop's physical battery locking toggles outwards, release the old battery pack, and confirm that your original product label features matching tracking IDs like KU533AA, AV08XL, HSTNN-LB60, or 484788-001.
