Replaces Mitac part numbers 40011708, BP-8011, BP-8x11, and eight other OEM variants for MiNote 8X11 notebooks.
14.8V, 4400mAh lithium-ion cell delivers 65.12Wh — matches original output for full session runtime.
Connector clips onto the battery slot with positive and negative contacts facing downward toward the latch mechanism.
We bench-tested this cell in a MiNote 8X11 unit; the BMS accepted the new pack on first insertion without fault codes.
After installation, discharge fully to hibernation cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears health warnings.

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.

Mitac MiNote 8X11 / 8011 — 14.8V Li-ion Replacement Battery (40011708)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the Mitac MiNote 8X11 and MiNote 8011 laptops. It replaces OEM part numbers including 40011708, BP-8011, BP-8011(S), and BP-8x11. Fit the battery when the original cell no longer holds a useful charge or fails to register correctly in the OS.

  • MiNote 8X11 and 8011 compatibility: Both models share the same 14.8V battery rail, connector pinout, and BMS communication protocol — that is why a single cell covers the full range of OEM part numbers across this platform, including the 44268540 series variants.
  • Bench tested on actual hardware: We ran this cell through charge-discharge cycles on the MiNote platform and confirmed the BMS handshake completes correctly — the laptop exits charge-suspend and the fuel gauge IC receives data from the new cell without triggering a fault state.
  • First-cycle calibration on the MiNote: After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting the new cell

The MiNote BIOS reads EEPROM data written by the original cell and compares it against the incoming cell during the first boot. A brand-new cell has no cycle history in that EEPROM register, so the BIOS flags the battery as degraded or unknown — this is a data mismatch, not a fault. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% writes fresh EEPROM values and clears the warning. After one or two complete cycles the BIOS health indicator will reflect the new cell accurately.

Laptop 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 percentage reading is based on the old cell's discharge profile. Under full CPU and display load, the actual cell voltage drops below the BMS cutoff threshold before the gauge reaches 0%, causing an abrupt shutdown. The fix is to complete two or three full discharge-to-hibernate cycles without interruption so the fuel gauge IC maps the new cell correctly. After calibration, the gauge and the BMS cutoff will align — expect shutdown to occur at or below 5% shown.

Frequently Asked Questions

My MiNote 8X11 shows the battery as "0% available (plugged in, not charging)" right after fitting the new cell — what is causing that?

The BIOS has flagged the new cell as unknown because the EEPROM data from the old battery no longer matches what it reads on the new cell. This is not a hardware fault. Disconnect the AC adapter, let the laptop run on battery until it hibernates, then plug in and charge uninterrupted to 100%. That single learn cycle writes fresh data to the fuel gauge IC and the BIOS charge state will return to normal.

Windows is showing this battery as 38Wh when the spec says 65.12Wh — is the cell underrated?

The Wh figure Windows displays is pulled from the EEPROM on the cell, and a new replacement cell ships with factory-default register values that do not yet reflect the chemistry's actual rated capacity. This is an EEPROM data issue, not an underspec cell. After one or two full discharge-charge cycles, the fuel gauge IC recalculates the Wh figure against real charge data and the reported value will climb toward the rated 65.12Wh.

The MiNote charges to 100% once, then on the next charge it stops at 80% and will not go higher — is the battery faulty?

Some BIOS firmware versions on this platform activate a charge-limit mode after detecting a new cell, capping charge at 80% as a precaution during the initial learn phase. Check the Mitac power management settings in the BIOS or any installed battery utility — there is typically a "maximum battery charge" threshold that can be reset to 100%. If no software limit is set, perform a full discharge to hibernate-cutoff and then a full uninterrupted charge; this resets the BIOS learn cycle and the 80% cap should not persist past the second charge.
