Medion MD95132 Laptop Replacement Battery 14.8V 4400mAh

Medion MD95132 / MIM2060 — 14.8V Li-ion Replacement Battery (40011708)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion battery for the Medion MD95132, MD95131, and MIM2060 notebooks. It replaces OEM part numbers including 40011708, BP-8011, and BP-8x11 series cells. If the original battery no longer holds a charge or the laptop dies without warning, this cell restores normal portable operation.

• MD95132 / MIM2060 / MD95131 platform: These three models share the same 14.8V four-cell battery architecture, the same connector pinout, and the same BMS communication protocol — which is why one cell fits all three. Swapping between them requires no hardware modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Medion notebook chassis. The BMS handshake completed without fault codes, charge current tapered correctly at full capacity, and the protection circuit tripped at the expected low-voltage threshold.
• Post-install calibration for Medion notebooks: After fitting this cell, run the laptop down until it hibernates on low battery, then charge it uninterrupted to 100% without interruption. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after fitting a new cell

The Medion BIOS stores battery health data in EEPROM and compares the new cell's reported capacity against the degraded profile of the old one. When the values don't match its cached baseline, it flags the new cell as unknown or poor health — even though the cell is fine. This is not a fault with the replacement battery. One full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and re-establishes the baseline. After two to three full cycles, the health indicator normalises.

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

This happens when the fuel gauge IC's calibration data no longer matches the new cell's actual voltage-to-capacity curve. The OS reads 25% remaining, but the cell voltage drops below the BMS cutoff threshold under combined CPU and display load before the gauge catches up. The fix is calibration: discharge fully to hibernate cutoff, then charge to 100% twice in succession without interrupting the charge cycle. After calibration, the gauge reads accurately and the early shutdowns stop — confirm by checking the cell voltage at reported 20% is above 14.0V.
