Bench-Tested Before It Ships At N.N Laptops, every battery is bench-tested on a dedicated load tester before it leaves the shop. We verify that the cell voltage is within specification, that the protection circuit does not trip under normal discharge, and that the BMS communicates correctly with the HP battery gauge so Windows reports accurate percentage readings. Units that show cell imbalance or below-spec capacity are rejected — you receive only batteries that pass our full quality check. This is a brand-new replacement battery , not a refurbished or pulled cell. What Is in the Box 1 x HP EliteBook 820 G3/G4 replacement battery (4-cell, 50Wh) No tools required — standard bottom-panel screw removal is sufficient Tip: before first use, run a full charge cycle to calibrate the BMS accurately Confirming the Right Part To be certain this is the correct battery for your laptop, flip the unit over and check the model sticker. If it reads HP EliteBook 820 G3 , 820 G4 , or 725 G3 , this pack fits. Unsure?
