The HP EliteBook 820 G3/G4 Battery is a direct-fit, grade-A replacement for the slim 12.5-inch EliteBook 820 series — the business ultrabook that thousands of professionals across Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, and Peshawar still rely on daily. Priced at Rs. 6,899 in 2026, this is one of the most competitive HP EliteBook 820 G3/G4 battery prices in Pakistan for a quality-checked unit that actually holds its rated charge.
Specifications & What Fits
This 4-cell Li-Polymer battery runs at 11.4V with a capacity of 4,400mAh / 50Wh — matching the original HP spec sheet exactly. It is compatible with the HP EliteBook 820 G3, HP EliteBook 820 G4, and HP EliteBook 725 G3. The part number cross-references HP PN 800231-141 / 800513-001 / HSTNN-UB6T families. The slim-profile form factor fits flush into the battery bay without any modification; the locking tab and multi-pin connector align precisely with the motherboard connector on the first seating.
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
