From $74.99 USD $92.99
Shipping calculated at checkout.
Fits HP Elite x2 1012 G1 hybrid laptops replacing OEM part MG04XL, HSTNN-DB7F, HSTNN-I72C, and MC04XL.
7.7V 4750mAh Li-Polymer cell delivers 36.58Wh — matches original output for full-day portable computing without throttle.
Connector slides straight into the battery slot with locking tab on the right side; verify tab engagement before closing the chassis.
We bench-tested this cell on an Elite x2 1012 G1 under mixed CPU and display loads; BMS handled charge acceptance cleanly on first insertion with no fault codes.
After installation, run one full discharge cycle to hibernation cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false poor-health warnings that appear after every cell swap.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HP Elite x2 1012 G1 — 7.7V Li-Polymer Replacement Battery (MG04XL)

This 7.7V, 4750mAh (36.58Wh) Li-Polymer cell replaces the MG04XL battery in the HP Elite x2 1012 G1 2-in-1 hybrid laptop. It fits the full Elite x2 1012 G1 lineup, including the Y0F40UP, Z9M72PC, V5B96US, and X5F29US configurations, plus 166 additional variants. Compatible OEM part numbers include 812060-2B1, 812205-001, HSTNN-DB7F, HSTNN-I72C, and MC04XL.

  • Elite x2 1012 G1 platform compatibility: All Elite x2 1012 G1 units share the same 7.7V battery rail, MG04XL connector pinout, and BMS handshake protocol regardless of regional SKU. One cell covers the entire model range without modification.
  • Bench tested on actual hardware: We ran this cell through charge, discharge, and BMS handshake verification on the Elite x2 1012 G1 platform. The BMS accepted the cell without fault codes, balanced cells correctly, and reported capacity within expected tolerance.
  • First-cycle calibration on the Elite x2 1012 G1: After installing, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or low-capacity warning that appears after every cell swap on this platform.

BIOS reporting poor battery health after installing a new MG04XL cell

The Elite x2 1012 G1 BIOS reads health data from the battery's EEPROM, which still carries charge-cycle counts and degradation flags from the old cell at the moment of swap. A new cell arrives with its own EEPROM baseline, and the BIOS treats the mismatch as evidence of a worn pack. This is a calibration state, not a hardware fault. Run the full discharge-to-hibernate then uninterrupted charge-to-100% cycle once, and the BIOS will rewrite the health register against the new cell's actual data.

Elite x2 1012 G1 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge reports 20–30% remaining, but the cell hits its low-voltage cutoff before the display figure reaches zero. Under combined CPU and display load, voltage sag accelerates this cliff. Complete two to three full discharge-to-hibernate and full charge cycles — after that, the gauge IC aligns its curve to the new cell and the shutdowns stop. Confirm the cell rests at 3.85V per cell at 50% displayed charge once calibrated.

Frequently Asked Questions

The HP Elite x2 1012 G1 shows the new battery as "0%" or "Unknown" in Windows right after installation — is the cell dead?

The fuel gauge IC on the Elite x2 1012 G1 has not yet mapped the new cell's voltage curve, so Windows reads the EEPROM data as incomplete and displays 0% or an unknown state. We see this on every cold-swap of the MG04XL — it is not a dead cell. Discharge fully to hibernate cutoff, then charge uninterrupted to 100%. After one complete cycle the fuel gauge IC resets its baseline and Windows reports correctly.

Why does the HP Elite x2 1012 G1 BIOS show a Wh rating that doesn't match the 36.58Wh spec on the battery listing?

The BIOS reads the Wh figure stored in the cell's EEPROM at manufacture, which reflects a rated chemistry value and may differ slightly from the actual 36.58Wh capacity in the product data. This is an EEPROM labelling difference, not a fault with the cell or the laptop. No action is needed — the BMS manages charge and cutoff against real voltage, not the EEPROM Wh figure. The discrepancy closes after one or two full calibration cycles as the learn cycle writes updated data.

Charge stops at 80% on the HP Elite x2 1012 G1 and won't go higher — what's blocking it?

HP's BIOS on the Elite x2 1012 G1 includes a firmware-controlled charge limit that caps charging at 80% when Battery Health Manager is active in BIOS settings. This is a BIOS feature, not a fault with the replacement cell. Open BIOS (F10 at startup), navigate to Power → Battery Health Manager, and set it to "Let HP manage my battery charging" or "Maximize my battery performance" to allow a full charge to 100%. The cell itself has no internal restriction at 80%.
