About this replacement
HP Pavilion DV4-5000 / DV6-7000 Series — 11.1V Li-ion Replacement Battery (HSTNN-YB3N)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion replacement battery for the HP Pavilion DV4-5000, DV4-5099, DV6-7000, DV6-7002 TX, and 418 additional models in these series. It replaces OEM part numbers including HSTNN-YB3N, HSTNN-LB3N, MO06, MO09, and PI06. The cell fits the standard battery bay and connects via the factory multi-pin connector on these Pavilion platforms.
- DV4-5000 and DV6-7000 platform fit: HP standardised the 11.1V three-cell Li-ion architecture and the same 9-pin SMBus connector across both the DV4-5000 and DV6-7000 chassis generations. This lets one battery cover a wide range of models without any adapter or modification.
- Bench tested on actual hardware: We cycled this cell on a DV6-7000 unit and monitored the BMS handshake through the SMBus. The protection circuit responded correctly to charge cutoff at 12.6V and discharge cutoff at 9.0V, with no spurious fault flags triggered.
- Post-install discharge cycle on HP Pavilion: After fitting this battery, run one full discharge until the laptop hibernates on low-battery cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to complete against the new cell and clears the inaccurate health warning that appears after every cell swap.
Why the DV4-5000 and DV6-7000 BIOS reports poor battery health after a cell swap
HP's BIOS reads cycle count, full-charge capacity, and wear level data stored in the battery's EEPROM. When a new cell arrives, that EEPROM data does not match what the system measured from the old pack — so the BIOS flags a health warning immediately. This is not a fault in the replacement cell. Running the learn cycle described above lets the BIOS re-populate its stored values from actual charge and discharge measurements. After one or two full cycles, the health warning clears and the reported capacity aligns with the rated 4400mAh.

This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The IC still uses discharge data from the old, degraded pack, so it maps the remaining capacity incorrectly against voltage. Under combined CPU and display load, the actual cell voltage drops faster than the gauge predicts — and the laptop hits the hardware undervoltage cutoff before the OS reaches 0%. Run two full discharge-to-hibernate and charge-to-100% cycles without interruption. After the second cycle the fuel gauge recalculates its end-of-discharge voltage reference and the shutdowns stop.
