Mitac Minote 8375 Replacement Battery 11.1V 6600mAh

Mitac Minote 8375 / 8575 — 11.1V Li-ion Replacement Battery (442671700002)

This is an 11.1V, 6600mAh lithium-ion replacement battery for the Mitac Minote 8375 and Minote 8575 notebook computers. It slots into the original battery bay and connects via the same multi-pin connector used across both Minote variants. Capacity is 73.26Wh, matching the original cell specification.

• Minote 8375 and 8575 shared platform: Both models run the same voltage rail and use identical battery connector pinouts, which is why a single cell covers both. The BMS handshake protocol and charge termination logic are consistent across the two, so no firmware conflict occurs on swap.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Minote platform. The BMS accepted the full 6600mAh without triggering premature cutoff, and charge termination fired correctly at 12.6V under the laptop's onboard charger.
• Post-swap calibration on the Minote: After fitting this cell, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell replacement on this platform.

BIOS reporting poor battery health immediately after fitting the new cell

The Minote BIOS stores cycle count and health data in the battery's EEPROM. When a new cell arrives, the BIOS reads unfamiliar EEPROM values and flags the battery as degraded or unknown. This is not a fault with the replacement cell. Running one complete discharge-to-hibernate followed by an uninterrupted full charge lets the BIOS re-learn the cell's actual capacity curve and clear the false health warning. After two or three full cycles, the health indicator stabilises.

Laptop shuts down at 20–30% charge shown on the gauge

This happens because the fuel gauge IC is still calibrated to the old, degraded cell. The percentage reading no longer maps accurately to actual cell voltage, so the laptop hits its low-voltage protection threshold while the display still shows 20–30% remaining. The underlying cause is a voltage cliff — the new cell's discharge curve differs from what the IC expects. Force a full discharge to hibernate cutoff, charge to 100%, and repeat two to three times. By the third cycle the fuel gauge IC recalibrates against the new cell and the shutdowns stop.
