14.8V at 2200mAh (32.56Wh) matches the original pack voltage and capacity for full runtime restoration on this chassis.
Connector seats into the HP battery slot with a single locking tab on the left side; verify the tab clicks fully before closing the service cover.
We bench-tested this cell in a 240 G4 with full CPU and display load; the BMS held 14.8V under sustained draw with no early cutoff or volt sag.
After installation, discharge fully to sleep mode, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HP 240 G4 / 245 G4 / 250 G4 Series — 14.8V Li-ion Replacement Battery (807611-131)

This is a 14.8V, 2200mAh (32.56Wh) Li-ion replacement battery for the HP 240 G4, 245 G4, 246 G4, and 250 G4 notebook series. It cross-references OEM part numbers including 807611-131, 807612-131, HS03, HS04, and HSTNN-LB6U among others. It fits the same battery bay, uses the same connector, and communicates with the HP EC firmware over the SMBus line.

  • 240 / 245 / 246 / 250 G4 platform fit: These four models share a common battery bay specification, SMBus pinout, and EC handshake protocol. HP used the HS03 and HS04 cell families across the entire G4 notebook line, so one cell covers the full range without modification.
  • Bench tested on actual hardware: We cycled this cell on a 250 G4 chassis and confirmed the EC accepted the EEPROM data, reported state-of-charge correctly, and held the charge curve through three full discharge-to-cutoff cycles without a BMS trip.
  • First-cycle calibration on the HP 240 G4: After fitting this cell, discharge the laptop fully until it hibernates, then charge uninterrupted to 100% without interruption. This resets the HP BIOS battery learn cycle and clears the inaccurate health warning that appears in HP Support Assistant after every cell swap.

BIOS reporting battery health as poor immediately after fitting a new cell

The HP BIOS reads health data from the battery EEPROM — a small memory chip on the cell that stores cycle count, rated capacity, and charge history. When a new cell arrives, that EEPROM data does not match what the BIOS logged from the old battery, so it flags a mismatch and reports poor health. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate cycle followed by a full uninterrupted charge. The BIOS recalibrates its fuel gauge IC against the new cell and clears the warning on the next boot.

Laptop shuts down abruptly at 20–30% charge shown on screen

This happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load before the OS fuel gauge reaches zero. The fuel gauge is calculated from a previous battery's discharge curve — it does not yet reflect the new cell's actual voltage-versus-capacity profile. The cell hits roughly 10.8V under load while the OS still reads 25%, and the BMS cuts power to protect the cell. Run two full calibration cycles as described above, and the fuel gauge will track the new cell's actual voltage cliff accurately.

Frequently Asked Questions

HP Support Assistant is showing the new battery as "Unknown" and 0% — is the cell dead on arrival?

It is not. The HP EC reads battery identity from the EEPROM on the cell, and immediately after a swap it has not yet completed a learn cycle against the new cell's data. Discharge the laptop fully to the hibernate cutoff point, then charge uninterrupted to 100% without removing the charger. After that cycle completes, reboot — the EC will have written fresh calibration data and Support Assistant will display the correct state-of-charge.

The system info screen shows a different Wh rating than the battery label — why don't the numbers match?

The Wh figure shown in Windows Device Manager or HP BIOS pulls from the EEPROM "design capacity" field, which is written at the cell factory and sometimes differs from the rated label by a small margin due to rounding in the chemistry specification. The actual usable energy is 32.56Wh as rated. This is an EEPROM metadata difference, not a capacity shortfall — confirm the real capacity by running a full discharge cycle and checking what the fuel gauge reports at 100% after recalibration.

The battery charges normally but the percentage jumps erratically — 60% one minute, 45% the next — what causes that?

The HP fuel gauge IC estimates state-of-charge by comparing live voltage and current readings against a discharge model built from the previous cell's history. With a new cell installed, that model is mismatched and produces unstable readings for the first few cycles. The gauge recalibrates itself as it collects discharge data from the new cell. Run two full discharge-to-hibernate then charge-to-100% cycles and the percentage readings will stabilise.
