About this replacement
HP Pavilion DM1-3000 Series — 11.1V Li-ion Replacement Battery (HSTNN-YB2D)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the HP Pavilion DM1-3000 series ultraportable notebook. It replaces OEM part numbers HSTNN-YB2D, GB06, 628419-001, and several other HP cross-references listed in the full compatibility table. The cell fits the DM1-3000, DM1-3000au, DM1-3001au, DM1-3002au, and over 86 additional variants in this lineup.
- DM1-3000 series compatibility: Every model in this range runs the same 11.1V battery rail, uses the same physical connector, and communicates via the same BMS handshake protocol — which is why one part number covers the full lineup without modification.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and a full BMS handshake verification on DM1-3000 series hardware. The BMS accepted the cell, negotiated correctly, and the charge cycle completed without cutoff errors or fault flags.
- First-cycle calibration on the DM1-3000: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that consistently appears after a cell swap on this platform.
BIOS reporting poor battery health immediately after installing a new cell
The DM1-3000 BIOS reads EEPROM data written by the original cell during its lifetime. When a new cell arrives, that EEPROM history is blank or mismatched, so the BIOS flags the battery as degraded — even though the cell is fresh. This is not a fault with the replacement. The BIOS needs at least one complete discharge-to-hibernate and full recharge cycle to build a new health baseline against the new cell's chemistry. After one or two full cycles, the health indicator corrects itself and the warning clears.
Laptop shuts down abruptly while the fuel gauge still shows 20–30% remaining
This is a voltage cliff issue, not a capacity fault. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track — the gauge is predicting remaining charge based on historical draw patterns, but the actual cell voltage hits the BMS cutoff threshold before the gauge catches up. The fuel gauge IC needs several real-world charge-discharge cycles against the new cell to recalibrate its model. Run three full discharge cycles to hibernate-cutoff followed by uninterrupted charges to 100%, and the shutdown threshold should stabilise above 5% remaining.
