SQU-1711 Thunderobot G7000M Replacement Battery 11.55V 4500mAh

Thunderobot G7000M / 911MT Series — 11.55V Li-Polymer Replacement Battery (SQU-1711)

This is an 11.55V 4500mAh (51.98Wh) Li-Polymer replacement battery for the Thunderobot G7000M, 911MT, 911ME, G8000M, and compatible models. It fits the SQU-1711 footprint and connector. The cell dimensions are 203.50 × 90.50 × 7.30mm — measure your original before ordering if you are unsure of your exact sub-variant.

• G7000M and 911-series compatibility: These models share a common battery bay format, connector pinout, and BMS handshake protocol tied to the SQU-1711 part number. Voltage rail, cell count, and PCB communication are consistent across the listed variants, which is why one cell covers the full group.
• Bench tested on actual hardware: We ran the cell through charge and discharge cycles on a G7000M unit and confirmed the BMS negotiated correctly with the system. The protection circuit responded to over-current and under-voltage triggers at expected thresholds. No false cutoff events occurred under sustained CPU and GPU load.
• First-cycle recalibration on G7000M: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the firmware throws after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting the SQU-1711

The G7000M firmware reads cycle count and health data stored in the old cell's EEPROM. When a new cell arrives with a fresh EEPROM, the BIOS interprets the data mismatch as a fault and flags the battery as degraded or unknown. This is a firmware read error, not a cell defect. Run one complete discharge-to-hibernate followed by a full uninterrupted charge — the BIOS learn cycle rewrites the health register against the new cell and the warning clears.

Laptop cutting off at 20–30% shown on the fuel gauge after battery swap

The fuel gauge IC on this platform calibrates its discharge curve against the original cell's impedance profile. A new cell has different internal resistance, so the gauge miscalculates the voltage cliff and triggers a low-battery shutdown earlier than the display percentage suggests. The fix is two to three full discharge-to-hibernate and full-charge cycles — this teaches the fuel gauge IC the actual capacity and cutoff voltage of the replacement cell. After calibration, the gauge should track consistently and shutdowns at 20–30% should stop. If the issue persists past three cycles, confirm the BIOS battery mode is not locked to a conserve-charge limit below 11.0V.
