Dell G7 17 7700 Replacement Battery 11.4V 8000mAh V0GMT

Dell G7 17 7700 — 11.4V Li-Polymer Replacement Battery (V0GMT)

This is an 11.4V, 8000mAh (91.2Wh) lithium-polymer replacement battery for the Dell G7 17 7700 gaming laptop. It fits the 17-inch G7 7700 chassis and connects via the original dock connector. OEM part numbers covered: V0GMT, 0NCC3D, 4K1VM, and 0W62W6.

• G7 17 7700 fitment: These four OEM part numbers all share the same 11.4V three-cell architecture, connector pinout, and BMS communication protocol used across the G7 7700 production run. The BIOS handshake reads the same EEPROM data structure, so the system accepts the cell without a firmware flag.
• Bench tested on actual hardware: We ran charge and discharge cycles on the G7 7700 platform. The BMS negotiated charge current correctly, the BIOS reported Wh capacity within normal tolerance, and the protection circuit responded to cell temperature as expected.
• First-cycle calibration on the G7 7700: 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 that appears after every cell swap on Dell's EC firmware.

BIOS reporting battery health as poor after fitting the G7 7700 replacement

The G7 7700 BIOS reads health data stored in the battery's EEPROM at POST. A new cell ships with factory EEPROM values that don't match the charge history the embedded controller expects. That mismatch triggers a "Battery Health: Poor" or "Consider Replacing" alert even when the cell is brand new. Running one complete discharge-to-hibernate then a full uninterrupted charge writes new baseline data into the learn cycle and the warning clears. If the warning persists after two full cycles, check the BIOS battery diagnostics page — a healthy cell will read above 95% design capacity at that stage.

This is a voltage cliff, not a fuel gauge error. Under full CPU plus discrete GPU plus display load, the G7 7700 draws enough current that a degraded or uncalibrated cell drops below the BMS cutoff voltage before the reported percentage reaches zero. The fuel gauge IC has not yet mapped the new cell's actual discharge curve, so the percentage shown is still based on the old cell's profile. Run two full calibration cycles — discharge to hibernate, charge to 100% — and the fuel gauge IC recalibrates against the new cell's voltage curve. After calibration, the shutdown threshold should align with a reported level below 5%.
