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 Dragonfly G4 Series — 11.58V Li-Polymer Replacement Battery (SS06XL)

This is a 11.58V, 5800mAh (67.16Wh) Li-Polymer replacement battery for the HP Dragonfly G4 ultrabook. It fits the 85H83PA, 819A0EA, 81A52EA, 818W2EA, and related Dragonfly G4 variants. OEM cross-references include SS06XL, M64310-271, M73476-005, and TPN-DB0O.

  • Dragonfly G4 platform fit: These Dragonfly G4 models share the same 11.58V three-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. The SS06XL designation covers the full G4 refresh line — swapping between listed models does not require firmware changes or hardware modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Dragonfly G4 unit. The BMS accepted the new cell without error, negotiated full charge capacity, and the BIOS fuel gauge updated correctly after a learn cycle. No charge rejection or protection-circuit trip occurred.
  • Post-install calibration on the Dragonfly G4: After fitting this battery, 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 appears in HP Support Assistant after a cell swap.

BIOS reporting poor battery health immediately after replacement

The HP Dragonfly G4 BIOS reads health data from EEPROM embedded in the battery pack, not from live cell voltage alone. When a new cell is installed, the EEPROM profile does not match the BIOS's stored charge history, so it flags the battery as degraded or unknown. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS to re-learn the cell's actual capacity curve and clear the warning.

Dragonfly G4 shutting down at 20–30% charge shown on screen

This symptom appears when the fuel gauge IC has not yet calibrated against the new cell's voltage-to-capacity curve. The OS reads a voltage that maps to 20–30% on the old cell's profile, but the new cell hits a voltage cliff at that point under combined CPU and display load. The laptop cuts power before the gauge reaches zero. To fix it, complete two to three full discharge-to-hibernate and charge-to-100% cycles so the fuel gauge IC recalibrates. After calibration, shutdowns at that percentage should stop.

Frequently Asked Questions

HP Support Assistant is showing the new battery as "unknown" or giving it a 0% health score — is the cell dead?

No. The Dragonfly G4 reads battery health from EEPROM data embedded in the pack, and a freshly installed cell carries no charge history the BIOS recognises. Discharge the laptop fully to hibernate cutoff, then charge uninterrupted to 100%. That single learn cycle writes usable data to the BIOS and clears the unknown or poor health flag in HP Support Assistant.

The OS fuel gauge is jumping around — it reads 60%, then suddenly 45%, then back to 55% within a few minutes. What's happening?

The fuel gauge IC on the Dragonfly G4 builds its capacity model from historical charge and discharge data stored for the old cell. With a new cell installed, that model is wrong, so the gauge interpolates voltage readings against a mismatched curve and produces erratic percentages. Run two to three complete discharge-to-hibernate and charge-to-100% cycles without interruption. After those calibration cycles, the IC maps the new cell's voltage curve accurately and the percentage readings stabilise.

The replacement battery stopped charging at 80% and won't go higher — is the cell faulty?

Almost certainly not. The HP Dragonfly G4 BIOS includes a Battery Health Manager setting that caps charging at 80% to reduce long-term cell stress. It ships enabled on some units and can be toggled on without users noticing. Open the BIOS setup (F10 at startup), navigate to Power → Battery Health Manager, and set it to "Let HP manage my battery charging" or "Maximize my battery" depending on your preference. The cell itself is not at fault — charging will reach 100% once the cap is lifted.
