Battery Care Tips
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
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 MD95800 / WIM2070 Series — 11.1V Li-ion Replacement Battery (BTP-ABBM)
This is an 11.1V 4400mAh Li-ion battery for the Medion MD95800 notebook. It also fits the WIM2070, MD95453, and MD95454. Capacity figures come from the product data — 48.84Wh.
- MD95800 and WIM2070 platform fit: These models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The same 11.1V three-cell configuration runs across this entire Medion chassis family, so one cell fits all listed models without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the MD95800 platform. The BMS completed the handshake correctly, the charge controller accepted full current, and cell voltage held flat across the discharge curve until the low-voltage cutoff tripped at the expected threshold.
- Post-install calibration on the MD95800: After fitting this cell, run a full discharge to hibernate 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 on this Medion platform.
BIOS reporting poor battery health immediately after fitting this cell
The MD95800 BIOS reads EEPROM data embedded in the original cell and compares it against the new one. When those values don't match, it flags the battery as degraded even though the cell is brand new. This is a data mismatch, not a hardware fault. Run one full discharge-to-hibernate then charge to 100% uninterrupted — after one or two complete cycles, the BIOS relearns the cell and the health warning clears.
Laptop shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC hasn't calibrated against the new cell yet. The gauge inherited capacity data from the old, degraded battery, so it misjudges where the actual voltage cliff sits. Under combined CPU and display load, the cell voltage drops faster than the stale gauge predicts, and the system shuts off to protect itself. Complete two full discharge-to-hibernate cycles, charging to 100% after each — the fuel gauge IC recalibrates and the reported percentage aligns with real cell voltage by cycle three.

Frequently Asked Questions
Windows shows the Medion MD95800 battery as "0% available (plugged in, not charging)" right after fitting the new cell — what's happening?
The charge controller on this platform sometimes won't begin charging until it completes an initial BMS handshake with the new cell. Shut the laptop down fully, leave the new battery seated for five minutes, then power on with the AC adapter connected. If the gauge still reads 0%, discharge the cell on battery power until the system hibernates, then charge uninterrupted to 100% — this establishes the handshake and the charge controller resumes normal operation.
The system information panel shows the wrong Wh rating for this replacement cell — should I be concerned?
No. The Wh figure shown in Windows or the BIOS comes from EEPROM data written to the original cell at the factory, not from a live measurement of the new cell. The MD95800 reads that stored value and displays it, so a mismatch after a cell swap is expected. The actual chemistry in this battery is rated at 48.84Wh — run one full calibration cycle and the reported figure will update to reflect the new cell's data.
The Medion MD95800 fuel gauge is jumping around — 40%, then 65%, then back down — after the battery swap. Is the cell faulty?
The fuel gauge IC on this platform calibrates itself against cycle history stored in the old cell. A new cell resets that history, and the IC makes large corrections while it learns the new discharge curve. This erratic behaviour is normal for the first two to three cycles. Complete two full discharge-to-hibernate cycles with uninterrupted charges to 100% after each — the gauge stabilises once the IC has enough data points to map the new cell's voltage curve accurately.
