HP Business Notebook N1050v Compatible Battery 14.8V 4400mAh

HP Business Notebook N1050v Series — 14.8V Li-ion Replacement Battery (361742-001)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for HP Business Notebook laptops. It fits the N1050v, NX9040, NX9000, and NX9005 series. It replaces OEM parts including 361742-001, 371785-001, HSTNN-DB13, and F4809A, among others listed above.

• N1050v and NX9000 series compatibility: These four HP Business Notebook lines share the same 14.8V four-cell Li-ion architecture, physical connector pinout, and BMS handshake protocol — which is why one cell pack covers all of them.
• Bench tested on actual hardware: We cycled this cell on an N1050v chassis and confirmed the BMS negotiated charge handshake correctly, cells balanced across all four groups, and the pack reached full charge without tripping protection cutoff.
• Post-install discharge cycle on the N1050v: After fitting this battery, run the laptop on battery only until it hibernates from low charge, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after fitting a new cell

The HP BIOS reads health data stored in the battery's EEPROM, not live cell voltage. When you swap cells, the EEPROM data from the old pack doesn't match the new chemistry, so the BIOS flags it as degraded before a single charge cycle completes. Run one full discharge-to-hibernate then an uninterrupted charge to 100% — this triggers the BIOS learn cycle and rewrites the health register. After two to three full cycles, the reported health status normalises.

Laptop shuts down at 20–30% charge shown on the gauge

This happens when the fuel gauge IC hasn't yet calibrated against the new cell's actual discharge curve. The gauge borrows the old cell's curve, which diverges sharply at lower charge states, so it reads 25% while the cell is already near cutoff voltage. Under full CPU plus display load, the voltage cliff hits faster than the gauge expects, and the system cuts power to protect the cells. Run two complete discharge-to-hibernate and charge-to-100% cycles — the fuel gauge IC recalibrates and the shutdowns stop. After calibration, watch for a stable cutoff around 10.5–11V under load.
