Up to 17% off
New arrival
From $133.99 USD $160.99
Shipping calculated at checkout.
Fits Medion MD96442, MD96559, MD96570, and MD97900 notebooks; replaces OEM part numbers BTP-BGBM, BTP-BFBM, and 40018875.
Delivers 10.8V and 8800mAh capacity, matching the original lithium-ion pack's energy output for full notebook runtime.
Connector seats flush into the battery bay with the locking tab engaged; orientation matches the original cell alignment.
We bench-tested this cell in an MD96442 chassis; the BMS reported healthy voltage curve and full charge acceptance without cutoff faults.
After installation, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear 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,
Michael

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.

Medion MD96442 / MD96559 / MD97900 Series — 10.8V Li-ion Replacement Battery (BTP-BGBM)

This is a 10.8V, 8800mAh (95.04Wh) Li-ion battery for Medion notebooks including the MD96442, MD96559, MD96570, and MD97900. It replaces OEM part numbers BTP-BGBM, BTP-BFBM, and 40018875. The connector and BMS handshake match the original Medion battery specification for these models.

  • MD96442 / MD96559 / MD96570 / MD97900 compatibility: These notebooks share the same 10.8V battery platform, connector pinout, and BMS communication protocol — one cell fits all listed models without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an MD-series board. The BMS accepted the new cell, communicated state-of-charge data correctly, and charge termination triggered at the expected voltage ceiling.
  • First-cycle calibration on Medion notebooks: After fitting this battery, run a full discharge until the laptop hibernates, 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 Medion firmware.

BIOS reporting battery health as poor after fitting a new cell

Medion notebooks store battery health data in EEPROM on the old cell. When a new battery is fitted, the BIOS compares the fresh cell against stale EEPROM values and flags it as degraded — even though the cell is new. This is a firmware-side calibration gap, not a fault with the replacement battery. Run one full discharge-to-hibernate cycle followed by a full uninterrupted charge. After two to three cycles, the BIOS fuel gauge IC recalibrates against the actual cell capacity and the health warning clears.

Laptop shuts down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet mapped the new cell's voltage curve — the percentage displayed does not match the actual remaining cell voltage. Under combined CPU and display load, the cell hits a voltage cliff that the OS did not anticipate, and the system shuts off to protect itself. It is not a fault with this battery. Run two full discharge-to-hibernate cycles with the laptop under normal use, then recharge fully each time — the fuel gauge will track the actual voltage curve accurately by the third cycle, and shutdowns at false percentages will stop.

Frequently Asked Questions

My Medion MD96442 shows 0% and "plugged in, not charging" right after fitting the new battery — what's wrong?

The BIOS is reading stale EEPROM data from the old cell and has not yet recognised the new one. Disconnect the AC adapter, hold the power button for 15 seconds to drain residual charge from the board, then reconnect and power on. If the fault persists, enter the BIOS, let it detect the battery fresh on boot, then run a full discharge-to-hibernate cycle followed by a complete uninterrupted charge to 100%.

Windows is showing the wrong Wh rating for this battery — it says around 48Wh but the cell is 95.04Wh. Is the battery faulty?

The Wh value Windows displays is pulled from EEPROM data embedded in the battery circuit — on a new replacement cell, that EEPROM figure sometimes reflects a different-capacity variant in the same OEM family rather than the actual chemistry installed. The cell itself is 95.04Wh as rated. Run two full calibration cycles and check whether the figure updates; on some Medion firmware builds, the reported Wh corrects itself once the fuel gauge IC has logged actual discharge data from the new cell.

The new battery charges fine but the percentage jumps erratically — it reads 60%, then skips to 85% within minutes. Why?

The fuel gauge IC inside the laptop maps charge percentage against a voltage lookup table built from the old cell's history. A fresh 8800mAh cell has a slightly different voltage-to-capacity curve, so the IC's estimates are off until it has logged real discharge data. This is a calibration issue, not a hardware fault. Run three full discharge-to-hibernate cycles with the laptop under normal load, charging fully after each one — by the third cycle the IC will have built an accurate map of the new cell and the percentage readout will stabilise.
