About this replacement
Razer Blade Pro GTX 1060 — 11.4V Li-Polymer Replacement Battery (RC30-0220)
This is an 11.4V, 6100mAh (69.54Wh) Li-Polymer battery for the Razer Blade Pro GTX 1060 and related Blade Pro 17 variants. It replaces OEM part RC30-0220 using the same cell format, voltage rails, and connector orientation. Compatible models include the Blade Pro 2017 GTX 1060, Blade Pro 17 2019 Full HD, and Blade Pro 17 2019 4K UHD.
- Blade Pro GTX 1060 / Blade Pro 17 platform: These models share the RC30-0220 footprint, connector pinout, and 11.4V BMS handshake. The same cell works across the 2017 and 2019 Blade Pro 17 variants because Razer kept the battery bay and charge controller consistent across that generation.
- Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on a Blade Pro unit. The BMS negotiated correctly with the EC, charge current tapered normally at top-of-charge, and no fault codes appeared during the test sequence.
- Post-install calibration on Razer Blade Pro: After fitting this cell, run the laptop down to hibernate-cutoff under normal use, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that nearly always appears after a cell swap on Blade Pro hardware.

This is a voltage cliff issue, not a capacity fault. Under combined CPU and display load, the new cell's voltage drops faster than the fuel gauge IC expects based on its stored discharge curve. The EC sees the voltage drop below the shutdown threshold before the percentage counter catches up. Run two full discharge-to-hibernate cycles under load to let the fuel gauge IC recalibrate against the new cell's actual curve — after that, the shutdown point typically drops below 5%.
BIOS reporting wrong Wh rating after installing RC30-0220
The Wh value shown in BIOS and Windows Battery Report is pulled from the cell's EEPROM, which stores the rated capacity at manufacture. Replacement cells often carry a slightly different EEPROM value than the original, so the system may display 68Wh or 71Wh instead of 69.54Wh. This is a data mismatch between the stored EEPROM figure and the chemistry spec — it does not affect actual charge capacity or how the battery performs. No action is needed; the charge controller uses voltage and current data, not the EEPROM Wh field, to manage charging.
