HP Envy X2 13" Replacement Battery - Replaces BV02XL

Why this battery

Fits HP Envy X2 13" detachable display unit; replaces BV02XL, HSTNN-IB6Q, 776621-001, and eight other OEM part numbers.
7.6V and 4200mAh capacity matches the tablet component's original power delivery and charge cycle count.
Connector slides into the proprietary slot on the display back panel with a small locking tab that clicks when seated correctly.
We ran this cell through five full discharge-to-shutoff cycles on the detachable unit; the BMS held steady voltage under display-only load and flagged no communication errors.
After installation, fully discharge the tablet to system hibernation, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

About this replacement

HP Envy X2 13" — 7.6V Li-Polymer Replacement Battery (BV02XL)

This is a 7.6V, 4200mAh (31.92Wh) lithium-polymer replacement battery for the HP Envy X2 13" detachable hybrid. It fits the display unit — the tablet half of the 2-in-1. Compatible OEM part numbers include BV02XL, 776621-001, HSTNN-IB6Q, and TPN-I116, covering the Envy X2 13-J000 series and related variants.

Envy X2 13" display unit compatibility: These models share the same flat Li-Polymer cell, 7.6V voltage rail, and connector pinout on the detachable display board. The BMS handshake is identical across the J000 series variants, so one cell covers the full range.
Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Envy X2 platform. The BMS accepted the cell without fault flags, balanced correctly at full charge, and held the 7.6V nominal rail under load without sagging to cutoff.
Post-install discharge cycle: After fitting this cell, 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 after every cell swap on the Envy X2.

BIOS reporting poor battery health after replacing the Envy X2 cell

When you swap the cell, the BIOS still holds EEPROM data from the old battery. That data includes cycle count, wear level, and rated capacity — all tied to the original cell's history. Until the learn cycle runs, the BIOS compares the new cell against stale figures and flags it as degraded. One full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the firmware to re-anchor its reference points to the new cell. After that cycle, the health warning clears and the reported capacity aligns with the 31.92Wh rating.

Fuel gauge showing wildly wrong percentage for the first few charges

The fuel gauge IC on the Envy X2 estimates state of charge by tracking voltage curves it learned from the old cell. A new cell has a different voltage-to-capacity curve until the IC calibrates against it. You'll see jumps — 40% dropping to 10% instantly, or the gauge stalling near full. Run two to three full discharge and charge cycles without interrupting either phase. By the third cycle the IC has enough data points to track the new cell accurately and the percentage readout stabilises.
