CM03XL Block Internal Layout Blueprint: This professional-grade 11.10V Lithium-Polymer (Li-Polymer) internal replacement battery pack features a specialized dense-profile architecture measuring exactly 198.80 x 102.80 x 8.40 mm and weighing 274.35 g. It seats securely inside the designated sub-frame battery bay without placing upward stress on your internal hardware components, preventing palm rest warps or trackpad button stiffness.

Model Generation & Series Verification (Crucial Rule): This custom power module is engineered exclusively for the first and second generations (G1 and G2) of HP’s flagship enterprise platforms, specifically the HP EliteBook 840 G1/G2, 850 G1/G2, 740 G1/G2, 745 G1/G2, 750 G1/G2, alongside the ZBook 14 Mobile Workstation and ZBook 15u G2. Please note that it will not fit subsequent generations (such as EliteBook 840 G3 or G4 lines), which transitioned to a wider, completely flat internal layout. Before completing your purchase, slide off your laptop's toolless bottom service door or unscrew the lower shield to verify that your stock battery shows matching part numbers like CM03XL, CM03, HSTNN-D840, or 717375-001.
