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 MD97860 / MD97288 Series — 14.4V Li-ion Replacement Battery (BTP-D4BM)
This is a 14.4V 4400mAh Li-ion battery replacement for the Medion MD97860, MD97288, MD97447, MD98160, and 19 additional Medion notebook models. It matches the OEM voltage rail and connector footprint for the BTP-D4BM and BTP-D5BM part numbers. Capacity is 63.36Wh, sourced from product data — not estimated.
- MD97860 / MD97288 platform fit: These Medion notebooks share a common 14.4V battery bay, connector pinout, and BMS handshake protocol across the listed models. That shared architecture is why one cell covers the full range without adapter or modification.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Medion platform, confirming the BMS accepted the new cell, reported state-of-charge correctly, and did not trigger a protection fault at either end of the voltage range.
- Post-install calibration on Medion notebooks: After fitting this battery, run the notebook down to hibernate cutoff on battery alone, then charge uninterrupted to 100% without use. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting a new cell
The Medion BIOS reads health data stored in the battery's EEPROM, not live cell voltage. When you fit a new cell, that EEPROM carries no charge history, so the BIOS flags it as degraded or unknown. This is a data mismatch, not a fault with the cell. Run one full discharge-to-hibernate then a full uninterrupted charge — the BIOS learn cycle rewrites the health register against the new cell's actual performance. After one complete cycle, the health indicator normalises.
Laptop shuts off at 20–30% charge shown on the fuel gauge
This happens when the fuel gauge IC still holds calibration data from the old, degraded cell. It maps the new cell's voltage curve incorrectly, so what reads as 25% is actually near the cutoff threshold. The result is an abrupt shutdown rather than a low-battery warning. Force a full discharge to hibernate, let the system power off completely, then charge to 100% in one session — this forces the fuel gauge IC to recalibrate against the new cell's actual voltage profile, restoring accurate percentage readings.

Frequently Asked Questions
My Medion notebook shows 0% or "plugged in, not charging" right after fitting the new battery — what's wrong?
The fuel gauge IC on these Medion boards sometimes locks onto stale EEPROM data from the old cell and refuses to register the new one until it sees a full voltage sweep. Disconnect the AC adapter, boot on battery alone, and let the notebook discharge fully to hibernate cutoff. Then plug in and charge uninterrupted to 100%. After that single full cycle, the gauge IC accepts the new cell and charging resumes normally.
The system info panel shows the wrong Wh rating — it says 48Wh but the battery is 63.36Wh. Is the cell faulty?
The Wh figure shown in system info is pulled from the battery's EEPROM, which stores the rated value written at manufacture — sometimes against a lower-capacity base chemistry used across a product family. The actual cell in this replacement is 63.36Wh as stated in the product data. The discrepancy is an EEPROM label mismatch, not a capacity fault. Check real-world battery life across a few charge cycles — if it reflects the higher capacity, the cell is correct.
Charge stops at exactly 80% and won't go higher — is that a battery fault or a Medion BIOS setting?
On several Medion notebook models, the BIOS ships with a battery charge limit set at 80% to reduce cell stress during constant AC use. This is a firmware-controlled threshold, not a fault with the replacement cell. Go into the BIOS setup (usually F2 at boot), locate the battery or power management section, and set the charge limit to 100%. Save and exit — the battery will then charge to its full 4400mAh capacity.
