Machenike F117-B6 Compatible Battery 11.4V 4000mAh GK5CN-00-13-3S1P-0

Machenike F117-B6 / F117-FP6R2 Series — 11.4V Li-Polymer Replacement Battery (GK5CN-00-13-3S1P-0)

This is an 11.4V, 4000mAh (45.6Wh) lithium-polymer battery for the Machenike F117-B6 and related F117 series gaming laptops. It replaces OEM part numbers GK5CN-00-13-3S1P-0 and GK5CN-00-B-3S1P-0. Fit models include the F117-FP6R2, F117-B3, X8Ti, and 13 additional variants sharing the same cell format and connector pinout.

• F117 series compatibility: These models share a 3S1P cell configuration running an 11.4V nominal rail with a consistent BMS connector and charge handshake protocol. Swapping between F117 variants requires no firmware change — the BMS negotiates directly with the EC on first charge.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on an F117-series board, confirming BMS communication, correct charge termination at 12.6V, and stable cutoff behaviour under simulated CPU plus display load conditions.
• Post-install calibration for the F117: After fitting, run the laptop on battery until it hibernates at low-voltage cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the EC logs when it detects new cell EEPROM data.

BIOS reporting poor battery health immediately after swap on the F117

The F117's embedded controller reads health data from the EEPROM on the cell. A new cell ships with default EEPROM values the EC does not recognise as a match to its stored baseline, so it flags poor health on the first boot. This is an EC data mismatch, not a cell fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the EC to rewrite its baseline against the new cell. After that cycle, the health warning clears and the gauge reads accurately.

F117 shutting down abruptly at 20–30% charge shown

This happens when the cell voltage drops sharply under the combined load of the CPU boost state and the display backlight — a voltage cliff the fuel gauge IC fails to predict from a degraded or miscalibrated state. The OS reads state-of-charge from a fuel gauge model built on the old cell's discharge curve, so the percentage shown no longer matches actual cell voltage. Under peak draw, the cell hits the EC's hard undervoltage cutoff before the gauge reaches zero. Run one full calibration cycle as described above; the fuel gauge IC recalculates its model, and the gauge will track accurately down to cutoff from that point forward.
