About this replacement
Razer Blade 14 / Blade Pro 17 — 11.1V Li-Polymer Replacement Battery (GMS-C60)
This 11.1V 5100mAh (56.61Wh) Li-Polymer battery replaces the original cell in the Razer Blade 14 (RZ09-00830500-R3U1, RZ09-00830100-R3U1) and Blade Pro 17 2012 (RZ09-00710100-R3U1), among other models. It matches the OEM GMS-C60 spec and the 3ICP8/38/83-2 cell stack. Physical dimensions are 297.50 × 77.16 × 8.10mm — verify these against your existing cell before ordering.
- Blade 14 and Blade Pro 17 2012 shared platform: Both models run the same 11.1V three-cell Li-Polymer configuration with identical connector pinout and BMS handshake protocol. The BIOS reads cell data through a shared SMBus line, so the same GMS-C60 part number works across all listed models without adapter or rewiring.
- Bench tested on actual hardware: We ran this cell on a Blade 14 chassis and cycled it through charge and discharge under mixed CPU and display load. The BMS responded correctly to charge cutoff at full voltage and held communication with the SMBus throughout — no dropped handshake or forced AC-only mode.
- Post-install discharge cycle on Blade hardware: After fitting this battery, run one full discharge until the laptop hibernates on low-battery cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears immediately after every cell swap on Razer firmware.
BIOS reporting poor battery health immediately after fitting a new cell
The Blade BIOS reads health data from EEPROM embedded in the original cell. When a new cell goes in, that EEPROM data is gone and the firmware flags the battery as degraded or unknown before any cycles have run. This is a firmware state, not a fault with the replacement cell. Running one complete discharge-to-hibernate followed by a full uninterrupted charge gives the BIOS enough data to recalibrate. After two to three cycles the health reading normalises and the warning clears.
Blade shutting down at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The OS gauge shows 25% remaining but the cell voltage has already dropped below the BMS cutoff threshold under full CPU and display load — the laptop shuts off because the real voltage and the reported percentage have diverged. It is not a defective cell. Run two to three full discharge-to-hibernate and uninterrupted full-charge cycles so the fuel gauge IC can map the new cell's voltage profile accurately. After calibration the shutdown point will align with the displayed percentage.
