⚠️ IMPORTANT BUYING NOTICE:

• SB03XL 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 189.60 x 98.00 x 12.50 mm and weighing 296.35 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 of HP’s ultra-portable 12.5-inch enterprise platforms, specifically the HP EliteBook 820 G1, 820 G2, 720 G1, 720 G2, and 725 G2 series. Please note that it will not fit newer generations (such as the EliteBook 820 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 SB03XL, SB03044XL, HSTNN-LB4T, or 717378-001.
