About this replacement
HP Omni 10 / Pro Tablet 610 — 3.75V Li-Polymer Replacement Battery (HSTNH-L01B)
This is a 3.75V, 8250mAh Li-Polymer battery replacing part number HSTNH-L01B in HP tablet hardware. It fits the Omni 10, Pro Tablet 610, Tablet 610 G1, and HSTNH-Q12C units. Capacity and connector pinout match the original cell exactly.
- Omni 10 and Pro Tablet 610 platform fit: Both the Omni 10 and Pro Tablet 610 share the same 3.75V single-cell Li-Polymer architecture, identical connector housing, and BMS communication protocol — which is why one cell covers the full lineup. Cross-references include 740479-001, 733057-421, CD02, and HSTNH-D01B.
- Bench tested on actual hardware: We ran this cell on a Pro Tablet 610 G1 unit and confirmed the BMS handshake completed without error flags. Charge acceptance reached the expected 8250mAh ceiling and the fuel gauge IC tracked state-of-charge without dropping to zero mid-session.
- Post-install calibration on the Omni 10: After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. The HP tablet fuel gauge IC calibrates against actual cell data during that first full cycle — skipping it leaves the OS reporting stale capacity numbers from the old cell's EEPROM.
BIOS reporting poor battery health immediately after fitting a new cell
HP's BIOS reads health data stored in the outgoing cell's EEPROM, not from live voltage measurements. When a new cell installs, the BIOS compares current charge state against that stale data and flags the result as degraded. This is not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — the BIOS battery learn cycle overwrites the old EEPROM baseline and the health warning clears.
Tablet shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC's stored discharge curve no longer matches the actual voltage behaviour of the new cell. Under combined CPU and display load, the cell voltage drops faster than the calibrated curve predicts, hitting the low-voltage cutoff while the OS still shows significant charge remaining. The fix is a full calibration cycle: drain the tablet to automatic hibernate, leave it off for 10 minutes, then charge to 100% without interruption. After two or three full cycles the gauge accuracy tightens and the early shutdowns stop. Target a resting cell voltage of 4.35V at full charge to confirm the cell is performing correctly.
