It drops securely flat into your laptop's designated internal chassis tray without generating outer casing alignment strain, lower plate warping, or mechanical trackpad click stiffness.

• Generation & Model Verification (Crucial Rule): This power layout is custom-engineered exclusively for the HP EliteBook 820 and 725 G3/G4 Series. Please note that it will not fit older EliteBook 820 G1 or G2 iterations, nor will it work with newer G5 or G6 models, which completely changed structural footprints, ribbon connector setups, and system voltages. Before completing your checkout order, please unscrew your notebook's bottom cover panel to verify that your factory original internal battery explicitly matches part numbers like SN03, SN03XL, SN03044XL, ST03XL, or 800514-001.
