About this replacement
HP Pavilion 15-CE015DX / Omen 15-ce Series — 15.4V Li-Polymer Replacement Battery (SR04XL)
This is a 15.4V Li-Polymer replacement battery rated at 4400mAh (67.76Wh) for the HP Pavilion 15-CE015DX and Omen 15-ce series laptops. It replaces OEM part SR04XL and cross-references including HSTNN-DB7W, TPN-Q193, and 917724-855. Install it when the original cell no longer holds a charge or the system shows a battery health warning.
- Pavilion 15-CE and Omen 15-ce platform fitment: Both lines share the same 15.4V four-cell battery architecture, connector pinout, and BMS handshake protocol — that is why a single part number covers both. The SR04XL OEM designation applies across the full platform, not just one model variant.
- Bench tested on actual hardware: We ran charge and discharge cycles on this cell and confirmed the BMS negotiated correctly with the HP EC firmware — no false "plugged in, not charging" state, and cell voltage held stable under sustained CPU and display load without tripping the low-voltage cutoff prematurely.
- Post-install calibration on HP EC firmware: After fitting this battery, run the system down to hibernate cutoff under normal use — do not force a shutdown — then charge uninterrupted to 100%. This resets the HP embedded controller battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
Why the Pavilion 15-CE shuts down at 20–30% after a battery swap
The HP embedded controller maps its shutdown thresholds against the EEPROM data stored in the old cell. When a new cell goes in, that map is stale and the fuel gauge IC has not yet calibrated against the new chemistry. Under full CPU plus display load, voltage sags faster than the controller expects, and it interprets that sag as a critically low state of charge. The fix is two to three full discharge-to-hibernate cycles charged back to 100% each time. After those cycles the fuel gauge IC recalibrates and the premature cutoffs stop.
BIOS reporting the replacement battery as unknown or 0% capacity
This happens because the HP BIOS reads battery identification and rated Wh from the cell's EEPROM on first boot. If the EEPROM profile in the replacement cell does not exactly match the original OEM record, the BIOS flags it as unrecognised and displays 0% or a generic unknown state. It is not a hardware fault. Boot into the HP BIOS setup, navigate to the battery information screen, and confirm the 67.76Wh rating registers correctly after the first full charge cycle completes. If the reading remains at 0%, reseat the battery connector and reboot — a loose pin on the five-pin connector is the most common physical cause on this platform.
