⚠️ IMPORTANT BUYING NOTICE:

• PR08 8-Cell Heavy-Duty External Layout Blueprint: This professional-grade 14.40V Lithium-Ion (Li-ion) replacement battery features a robust 8-cell stick-profile casing layout measuring exactly 268.40 x 50.20 x 20.20 mm and weighing 487.70 g. Engineered specifically to sustain larger desktop-replacement configurations, this external module slides cleanly into the rear docking tracks of your notebook's outer framework and locks instantly into position using dual spring-loaded chassis slider toggles, requiring no technical installation tools.

• Model Generation & Display Size Verification (Crucial Rule): This high-efficiency power pack is custom-engineered exclusively for the massive 17.3-inch aluminum HP ProBook 4730s and ProBook 4740s corporate workstations. Please note that it will not fit smaller 13-inch, 14-inch, or 15-inch ProBook models from the same generation (such as the ProBook 4330s, 4430s, or 4530s, which rely on the 6-cell PR06 profile). It features a wider physical depth profile designed strictly for the 17-inch chassis alignment tracks. Before completing your checkout, slide your laptop's physical release tabs, remove your stock battery, and verify that its casing explicitly features tracking markers like PR08, QK647AA, HSTNN-LB2S, or 633807-001.
