About this replacement
HP 14-EE0000 Series — 11.25V Li-Polymer Replacement Battery (AE03041XL)
This is an 11.25V, 3450mAh (38.81Wh) lithium-polymer replacement battery for HP 14-EE0000 series laptops. It fits the 14-EE0001NB, 14-EE0002NB, 14-EE0002NF, and over 580 additional variants in the EE0000 line. Cross-references include AE03XL, HSTNN-AB1B, HSTNN-OB3E, TPN-DB1M, and N20951-series part numbers.
- EE0000 series fit: All EE0000 variants share the same 11.25V three-cell architecture, connector pinout, and BMS handshake protocol. That common electrical spec is why one cell works across hundreds of sub-models in this line.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on EE0000-series hardware. The BMS communicated correctly, charge acceptance reached full capacity, and no fault codes were triggered during load testing.
- First-cycle calibration on EE0000 hardware: After installing, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting battery health as poor immediately after replacement
The HP EE0000 BIOS reads health data stored in the battery's EEPROM and compares it against historical charge cycles from the old cell. A brand-new cell has no charge history, so the BIOS flags it as degraded or unknown on first boot. This is not a fault with the replacement cell — it is a calibration gap. Running one full discharge-to-hibernate followed by an uninterrupted full charge gives the fuel gauge IC enough data to write accurate health values. After two to three complete cycles, the health warning clears and reported capacity stabilises.

This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. Under combined CPU and display load, the cell voltage drops faster than the old curve predicts, and the system cuts power before the gauge reaches 0%. The BIOS is acting on stale discharge data. Run two full discharge-to-hibernate cycles — both times let the laptop hibernate naturally rather than shutting it down manually — then charge to 100%. After the second full cycle, the gauge recalibrates and shutdowns at false percentages stop.
