Up to 20% off
New arrival
From $63.99 USD $79.99
Shipping calculated at checkout.
Fits Mitac MiNote 8X11 and MiNote 8011 notebooks, replaces OEM part numbers 40011708, BP-8011, BP-8011(S), and BP-8x11.
Delivers 14.8V at 2200mAh capacity, storing 32.56Wh total — sufficient for full-day unplugged operation on this ultraportable.
Connector slides into the original slot with positive lead forward and locking tab engaged on the right side.
We charged this cell in the MiNote dock and monitored BMS behavior — the pack accepted current smoothly through the full 0–100% cycle with no cutoff anomalies.
After installation, run one full discharge to hibernation-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.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

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, 2200mAh (32.56Wh) Li-ion battery pack for the Mitac MiNote 8X11 and MiNote 8011 notebooks. It cross-references OEM part numbers including 40011708, BP-8011, BP-8011(S), and BP-8x11. It replaces the original cell when the laptop no longer holds a usable charge away from the AC adapter.

  • MiNote 8X11 and 8011 platform fit: Both models share the same 14.8V battery bay, connector pinout, and BMS handshake protocol. A single cell revision covers both, which is why so many OEM part numbers — 4009657, 442685400001 through 442685400015, and others — point to the same physical pack.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the MiNote platform. The BMS communicated correctly with the system board, charge current tapered normally at full capacity, and no protection trips were triggered during load testing.
  • Post-install calibration on the MiNote: 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 commonly appears after a cell swap on this platform.

BIOS reporting battery health as poor immediately after fitting the new cell

The MiNote BIOS stores learned capacity data from the previous cell in firmware. When a new cell is installed, the BIOS compares current readings against that stored profile and flags a mismatch as poor health. This is not a fault with the replacement battery — it is stale EEPROM data. Run a full discharge-to-hibernate followed by a full uninterrupted charge. After two or three complete cycles, the BIOS rewrites its health profile against the new cell and the warning clears.

Fuel gauge reading wildly inaccurate for the first few charge cycles

The fuel gauge IC on the MiNote measures state-of-charge by tracking accumulated current in and out of the cell. After a cell swap, the IC has no baseline for the new cell's actual capacity curve, so its percentage estimates drift significantly — sometimes jumping from 60% to 15% with no warning. The IC needs two to three full calibration cycles to map the new cell's discharge profile accurately. Let the battery discharge fully to hibernate cutoff, charge to 100% without interruption, and repeat. By the third cycle, gauge accuracy stabilises and the percentage reading tracks reliably down to around 3.6V per cell under normal load.

Frequently Asked Questions

My MiNote shuts down at around 20–25% battery shown — is the new cell faulty?

The cell is most likely fine. The MiNote's CPU and display draw a combined load spike that causes the cell voltage to drop sharply at lower states of charge — what looks like 20% on the gauge is actually a voltage cliff where the cell can no longer sustain the load. This happens most often before the fuel gauge IC has completed its calibration cycles against the new cell. Run two or three full discharge-to-hibernate then full-charge cycles; the gauge IC recalibrates and the early shutdowns stop once it correctly maps the cell's usable voltage range down to approximately 14.0V pack cutoff.

The MiNote shows the battery as "0%" or "unknown" right after install — the laptop only runs on AC.

This points to the BIOS not yet recognising the new cell's EEPROM data. The system defaults to AC-only mode as a protection fallback when it cannot validate the battery. Shut down fully, remove the AC adapter, reseat the battery, then boot with AC connected. If the gauge still reads unknown after the first boot, perform a full discharge to hibernate cutoff and a complete uninterrupted charge to 100%; this forces the BIOS to write a fresh battery profile and clears the unknown status.

System info shows a different Wh rating than the 32.56Wh on the spec sheet — is the wrong battery fitted?

This is an EEPROM data difference, not a wrong battery. The Wh value displayed in Windows or the BIOS is read from the cell's EEPROM register, which may reflect the OEM-rated figure from a specific factory batch rather than the measured 32.56Wh chemistry value. The actual electrical capacity is unchanged. Confirm voltage reads 14.8V nominal in the battery report — if it does, the correct cell is installed and the Wh display discrepancy is a firmware label issue only.
