Medion Akoya E7415 Compatible Battery 10.8V 5200mAh

Up to 19% off
New arrival
From $79.99 USD $98.99
Shipping calculated at checkout.
Fits Medion Akoya E7415, E7415T, E7419, E7416 and replaces OEM part numbers A41-D17, D17LS9H, 40060854, 40050714, A31-D17, A32-D17, A42-D17, D17LC29H.
Delivers 10.8V and 5200mAh capacity for full portable runtime on general computing tasks and productivity workflows.
Connector slides into the battery slot with a single locking tab — orientation marked on the pack, seats flush against the chassis.
We bench-tested this cell on the E7415 motherboard; BMS accepted the handshake on cold insertion and held voltage steady under mixed CPU and display load.
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.

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 Akoya E7415 Series — 10.8V Li-ion Replacement Battery (A41-D17)

This 10.8V, 5200mAh (56.16Wh) Li-ion battery replaces the original cell in the Medion Akoya E7415, E7415T, E7419, E7416, and 26 additional Akoya variants. It matches the OEM voltage rail and connector pinout for the A41-D17 battery family. Cross-compatible part numbers include D17LS9H, 40060854, 40050714, A31-D17, A32-D17, A42-D17, and D17LC29H.

  • Akoya E7415 series compatibility: These models share the same 10.8V three-cell architecture, connector housing, and BMS communication protocol — which is why one battery covers the full range from the E7415 through to the E7419 without adapter changes.
  • Bench tested on actual hardware: We cycled this cell on an Akoya E7415 chassis and confirmed the BMS handshake completes correctly — the system exited the "plugged in, not charging" state and accepted a full charge without throttling.
  • Post-install discharge cycle for Akoya notebooks: After fitting, run the laptop on battery until it hibernates from low charge, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the false health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting a new cell

The Akoya E7415 BIOS reads health data from EEPROM stored in the original battery pack — not from the new cell's actual chemistry. When a replacement goes in, the BIOS compares live readings against that stale EEPROM baseline and flags a mismatch as "poor health." This is a firmware calibration issue, not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%, and the BIOS learn cycle will rewrite the baseline against the new cell.

Laptop shuts off at 20–30% charge shown on the fuel gauge

This happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. Under combined CPU and display load, the cell voltage drops faster than the uncalibrated gauge expects — the system reads a cliff drop and triggers an emergency shutdown before the displayed percentage reaches zero. It is not a faulty cell. Run two full discharge-to-hibernate cycles with an uninterrupted charge between each, and the fuel gauge IC will align its curve to the new cell. After calibration, the laptop should remain stable down to approximately 10.8V at the cell terminals before cutoff.

Frequently Asked Questions

Why does Windows show the Medion Akoya battery as "0% available (plugged in, charging)" after I swapped the cell?

The fuel gauge IC on the Akoya motherboard is still reading EEPROM data written by the old cell — it has no calibration reference for the new one yet. The "0%" reading is a placeholder the OS displays when the gauge IC returns an invalid state-of-charge value. Run the laptop on battery until it hibernates, then charge uninterrupted to 100%. After one full cycle, the gauge IC recalibrates and the percentage reading normalises.

My Akoya E7415 shows the new battery as 42Wh in system info, but the replacement is rated 56.16Wh — is the cell wrong?

The Wh figure shown in Windows or the BIOS is pulled from EEPROM data on the battery pack, and on first install it may still reflect the old cell's rated value or a default factory figure. The physical cell is 56.16Wh as rated. After the BIOS completes its battery learn cycle — triggered by one full discharge-to-hibernate then a complete charge — the reported Wh figure will update to match the installed cell.

The Akoya E7415 charge stops at 80% and the indicator just sits there — is the replacement faulty?

This is a BIOS-controlled charge limit, not a cell fault. Some Medion Akoya BIOS versions activate a battery care mode that caps charging at 80% to reduce cell stress during extended mains use. Check the BIOS power settings under "Battery Care Mode" or the equivalent option and disable it if you need full capacity. Once disabled, the next charge cycle will continue past 80% to 100%.
