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.

Medion MD89560 / Akoya P6622 — 14.4V Li-ion Replacement Battery (BTP-DDBM)

This is a 14.4V, 4400mAh (63.36Wh) Li-ion battery for the Medion MD89560, MD98250, Akoya P6622, Akoya P6630, and over 25 additional Medion notebook models. It replaces OEM part numbers BTP-DDBM, BTP-DBBM, BTP-D8BM, BTP-D9BM, and related variants. The cell fits the original battery bay and connects through the standard multi-pin Medion notebook connector.

  • Akoya and MD-series compatibility: These models share a common 14.4V four-cell architecture and the same BMS handshake protocol, which is why one cell covers such a wide range of Medion notebooks. The connector pinout and EEPROM communication spec are identical across this platform generation.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a Medion Akoya unit. The BMS accepted the EEPROM handshake without errors, charge current stepped down correctly at full capacity, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.
  • Post-installation cycle reset: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. Medion's BIOS battery-learn cycle resets against the new cell chemistry during this sequence, clearing the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after fitting a new cell

When a Medion notebook reads EEPROM data from the previous cell, it flags the new battery as degraded because the stored cycle count and capacity history don't match the fresh chemistry. The BIOS hasn't yet run its internal learn cycle against the new cell, so the health percentage shown is meaningless. Run one full discharge to hibernate, then a full uninterrupted charge to 100%. After that single calibration cycle, the BIOS recalculates from the actual cell data and the false warning clears.

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

This happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. Under combined CPU and display load, the actual cell voltage drops below what the gauge predicted, and the system hits an unexpected low-voltage cliff before the displayed percentage reaches zero. It is not a fault with the new cell — it is a calibration mismatch. Discharge fully to hibernate-cutoff twice in succession, charging completely between cycles, and the gauge IC will re-map its curve to the replacement cell's actual 14.4V profile.

Frequently Asked Questions

My Medion Akoya shows the replacement battery as "0% available (plugged in, not charging)" — what's happening?

The BIOS is reading stale EEPROM data from the old cell and hasn't accepted the new cell's identity yet. Shut the laptop down completely, remove the AC adapter for 30 seconds, reconnect, and boot into BIOS. Let it sit on the BIOS screen on AC power for two minutes, then exit and boot normally — this forces a fresh EEPROM handshake. If the 0% reading persists, run one full discharge to hibernate-cutoff and charge uninterrupted to 100% to complete the learn cycle.

The Wh rating shown in Windows Battery Report says 47Wh, but the replacement cell is rated 63.36Wh — which is correct?

The Windows Battery Report pulls the Wh figure from EEPROM data written to the original cell at manufacture — it reflects the old cell's rated chemistry, not the replacement. The physical replacement cell is 63.36Wh as rated. After one full calibration cycle (discharge to hibernate, uninterrupted charge to 100%), the fuel gauge IC updates its energy calculation against the new cell and the reported figure will move closer to the actual 63.36Wh rating.

New battery charges fine but the fuel gauge jumps erratically — showing 74%, then 91%, then back to 60% within minutes.

The fuel gauge IC inside the Medion notebook is still interpolating from the old cell's voltage-to-capacity curve, which doesn't match the new cell's chemistry. It overcorrects as current draw fluctuates, producing the erratic readout. Run two complete discharge-to-hibernate and full-charge cycles without interrupting either phase. By the end of the second cycle, the IC will have enough data points from the new cell to track charge state accurately.
