About this replacement
HP G6000 / dv2000 Series — 10.8V Li-ion Replacement Battery (HSTNN-IB31)
This is a 10.8V, 4400mAh Li-ion replacement battery for HP G6000, G7000, Pavilion dv2000, and dv2000T series laptops. It replaces OEM part numbers HSTNN-IB31, HSTNN-DB31, 432306-001, and several related HP part numbers. Physical dimensions are 205.20 × 59.20 × 37.50mm — confirm your original matches before installing.
- G6000 and dv2000 platform compatibility: HP used the same 10.8V three-cell battery rail and connector pinout across the G6000, G7000, and dv2000 chassis. The BMS handshake uses the same SMBus protocol, so one battery covers the full range of affected models.
- Bench tested on actual hardware: We cycled this cell on a G6000 unit and confirmed the BMS handshake completed without fault codes. The charge controller accepted full current from flat and the protection circuit tripped correctly at low-voltage cutoff.
- Post-install calibration for the G6000: After fitting, run the laptop off battery only until it hibernates on low power, then charge uninterrupted to 100% before rebooting. This resets the BIOS battery learn cycle and clears the false "poor health" warning that appears after every cell swap on this platform.
Why the G6000 BIOS reports poor health immediately after a battery swap
The HP G6000 BIOS stores battery health data in its own memory, tied to the EEPROM profile of the original cell. When a new cell is installed, that stored profile no longer matches, and the BIOS flags the battery as degraded before it has run a single cycle. This is not a fault with the replacement cell — it is a calibration mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to write a fresh health baseline against the new cell's actual capacity.
Laptop shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge reports 20–30% remaining, but the cell voltage under full CPU and display load drops below the BMS cutoff threshold before that figure reaches zero. The laptop cuts power to protect the cell, not because the battery is faulty. Run two to three full discharge and charge cycles without interruption — the fuel gauge IC recalibrates against real load data and the shutdowns stop.
