Micro Int Mint 6200 Replacement Battery 10.8V 6600mAh

Micro Int Mint 6200 — 10.8V Li-ion Replacement Battery (DR202)

This is a 10.8V, 6600mAh Li-ion battery for the Micro Int Mint 6200 notebook. It also cross-references as EMC36, ME202BB, NL2020, and SMP02. If the original cell no longer holds a charge or the laptop dies unexpectedly, this is the direct cell swap.

• Mint 6200 platform fit: The Mint 6200 uses a fixed 10.8V three-cell series configuration. The DR202 form factor locks the connector orientation and BMS handshake to that rail — swapping a generic cell at a different voltage trips the BIOS charge controller and prevents a full charge cycle.
• Bench tested on actual hardware: We cycled this cell through charge, full discharge to hibernate cutoff, and a second full charge. The BMS held the 10.8V nominal rail throughout, and the protection circuit tripped correctly at low-cell threshold — no runaway, no false full-charge flag.
• First-cycle reset on the Mint 6200: After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. The Mint 6200 BIOS runs a battery learn cycle on that sequence — skip it and the health indicator stays locked to the old cell's EEPROM data, showing a false "poor health" warning every boot.

BIOS reporting battery health as poor after fitting the DR202

The Mint 6200 BIOS reads health status from EEPROM data written during the battery learn cycle. When a new cell goes in, that data is blank or carries the previous cell's degraded profile. The BIOS interprets this as a fault and flags poor health at every boot. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the EEPROM baseline and clears the warning.

This is a voltage cliff failure, not a gauge error. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track — the BIOS sees the rail fall below the cutoff threshold and forces an immediate shutdown before the OS gauge reaches zero. It happens most on new cells that haven't completed calibration cycles yet. Run two full discharge-to-hibernate and full-charge cycles back to back — the fuel gauge IC recalibrates its load-curve model and the shutdowns stop.
