⚠️ IMPORTANT BUYING NOTICE:

• RR03XL Internal Compact Layout Blueprint: This professional-grade 11.40V Lithium-Polymer (Li-Polymer) internal replacement battery pack features a specialized thin-profile footprint measuring exactly 184.50 x 93.50 x 7.80 mm and weighing an agile 228.00 g. It seats securely flat into your laptop's designated internal chassis tray alignment guides without generating structural pressure against the lower baseplate panel, preventing palm rest warps or mechanical trackpad click stiffness.

• Model Generation & Series Verification (Crucial Rule): This high-efficiency power engine is custom-built exclusively for the fourth-generation HP ProBook 430 G4 and ProBook 440 G4 business notebook series (including regulatory models HSTNN-Q01C, HSTNN-Q02C, and HSTNN-Q03C). Please note that it will not fit older ProBook platforms (such as the ProBook 430 G1, G2, or G3 generations), nor will it fit later redesigned systems (such as the G5, G6, or newer G8/G9 lines). Those alternative iterations utilize completely disparate internal physical layouts, alternative terminal connection tabs, and completely different voltage grids. Before completing your checkout order, unscrew your notebook's lower base cover plate to physically verify that your stock factory battery explicitly features tracking part numbers like RR03XL, RR03, HSTNN-LB7I, or 851477-422.
