About this replacement
HP ENVY 16 / 16-f0035nr — 11.55V Li-Polymer Replacement Battery (FZ06083XL)
This is an 11.55V, 7150mAh Li-Polymer replacement battery for the HP ENVY 16 and HP 16-f0035nr laptop series. It replaces OEM part numbers FZ06083XL, FZ06XL, M47636-2C1, M47636-2D1, M48025-005, and TPN-DB0I. The cell fits the standard battery bay on the 16-f0035nr, 16t-f000, ENVY 16-H0000CI, ENVY 16-H0000NA, and over 256 additional HP ENVY 16 configurations.
- ENVY 16 platform fit: The HP ENVY 16 series shares a common 11.55V three-cell Li-Polymer architecture across its H0000 and f000 submodels. Each variant uses the same physical connector, cell tab layout, and BMS communication protocol — which is why a single part number covers the full lineup.
- Bench tested on actual hardware: We ran this cell on an ENVY 16-f0035nr unit and confirmed the BMS handshake completes correctly at first boot. The charge controller accepted the pack without triggering a fault state, and the fuel gauge IC began tracking state-of-charge within the first partial cycle.
- First-cycle calibration on HP ENVY 16: After installing this battery, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after any cell swap on this platform.
BIOS reporting poor battery health immediately after replacement
The HP ENVY 16 BIOS reads health data from the battery's EEPROM — the small memory chip embedded in the pack. When a new cell is installed, the EEPROM holds factory defaults that don't match any learned charge history, so the BIOS flags the pack as degraded. This is not a fault with the replacement cell. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% gives the BIOS enough data to rewrite the health estimate correctly. After two to three complete cycles, the health warning clears on its own.
Laptop shuts down at 20–30% remaining on the ENVY 16 gauge
This happens when the fuel gauge IC still holds calibration data from the old, degraded cell. When the new cell hits full CPU plus display load simultaneously, the IC misreads remaining capacity and sends a low-voltage shutdown signal earlier than it should. The fix is a calibration cycle: let the laptop discharge under normal load — screen on, active tasks running — all the way to hibernate, then charge back to 100% without interruption. After two full calibration cycles, the gauge reads correctly and the premature shutdown stops.
