Magitronic 600 DR202 Replacement Battery 10.8V 6600mAh

Magitronic 600 / 610 / 620 — 10.8V Li-ion Replacement Battery (DR202)

This is a 10.8V, 6600mAh (71.28Wh) lithium-ion battery for the Magitronic 600, 610, and 620 laptop series. It replaces OEM part numbers DR202, EMC36, ME202BB, NL2020, and SMP02. If your original cell no longer holds charge or fails to power the notebook away from the wall, this cell restores portable operation.

• 600 / 610 / 620 series fit: All three models share the same battery bay dimensions, connector pinout, and 10.8V voltage rail. The BMS communication protocol is identical across the series, so one cell covers all three without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Magitronic 600 platform. The BMS accepted the cell immediately, reported state-of-charge correctly after two calibration cycles, and held voltage stable under combined CPU and display load without triggering protection cutoff.
• Post-install calibration cycle: After fitting this cell, run the laptop down to hibernate-cutoff on battery, then charge uninterrupted to 100% before using it again. This resets the BIOS battery learn cycle 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 Magitronic 600 BIOS reads health data stored in the battery's EEPROM, not from live cell measurements. When a new cell arrives, the EEPROM values reflect factory defaults that don't match the BIOS's learned data from the old cell. The system flags a mismatch as degraded health. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% lets the BIOS rewrite its reference data against the new cell and clears the warning.

Laptop shuts down abruptly while the OS still shows 20–30% charge remaining

This happens when the fuel gauge IC calibration is misaligned with the new cell's actual capacity curve. The gauge reports 20–30% remaining, but the real cell voltage has already dropped below the threshold the system needs to sustain the CPU and display simultaneously. The fix is a full calibration cycle: discharge the laptop completely to automatic hibernate, then charge to 100% without interruption — repeat this two to three times. After three cycles the gauge IC maps accurately to the new cell and the shutdown behaviour stops.
