HP Elite x2 1013 Replacement Battery ME04XL 7.7V 6400mAh

HP Elite x2 1013 G3 — 7.7V Li-Polymer Replacement Battery (ME04XL)

This is a 7.7V, 6400mAh (49.28Wh) Li-Polymer battery for the HP Elite x2 1013 and Elite x2 1013 G3 series detachable 2-in-1. It replaces OEM part numbers ME04XL, ME04050XL, HSTNN-IB8D, 937434-855, 937519-171, and 937519-1C1. The slim 4.05mm cell profile matches the original slab geometry so the tablet module re-seats into the keyboard dock without clearance issues.

• Elite x2 1013 and 1013 G3 fitment: All variants in this line — including 2TT41EA and 2TT15EA — share the same 7.7V two-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. One cell revision covers the full G3 production run.
• Bench tested on actual hardware: We cycled this cell on an Elite x2 1013 G3 unit. The BMS accepted the new cell without a connector error, charge current ramped normally from constant-current to taper phase, and the SMBus data lines reported capacity within expected tolerance across three full cycles.
• First-cycle calibration on the Elite x2 1013: After fitting, run the tablet on battery until Windows forces hibernate, then charge uninterrupted to 100% before use. This forces the fuel gauge IC to re-learn the new cell's charge curve and clears the inaccurate health warning the BIOS logs after every cell swap.

BIOS reporting poor battery health immediately after fitting the ME04XL

The HP BIOS reads battery health from EEPROM data embedded in the cell's SMBus circuitry. A brand-new cell ships with factory-default EEPROM values that don't yet match the host system's learned charge history, so the BIOS flags it as degraded before a single charge cycle completes. This is a data mismatch, not a cell fault. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — this executes the BIOS battery learn cycle and writes fresh reference data. After two to three cycles the health reading normalises.

Elite x2 1013 shutting down abruptly at 20–30% shown on the gauge

This happens when the fuel gauge IC still holds calibration data from the old, degraded cell. Under combined CPU and display load, the new cell's actual voltage curve diverges from the IC's stored model, and the system hits a low-voltage protection threshold earlier than the percentage shown suggests. The fix is a full calibration cycle: discharge to automatic hibernate, then charge to 100% without interruption. After two complete cycles the gauge IC maps the new cell's voltage-to-capacity curve accurately and the early shutdowns stop. If the problem persists past three cycles, check that the BIOS is on the latest firmware — some G3 builds had a fuel gauge update bundled in a later revision.
