Razer RC30-0220 Replacement Battery 11.4V 6100mAh

Up to 19% off
New arrival
From $94.99 USD $116.99
Shipping calculated at checkout.
Fits Razer Blade Pro GTX 1060 and Blade Pro 17 2019 models, replaces OEM part RC30-0220.
11.4V and 6100mAh Li-Polymer cell delivers 69.54Wh to restore full unplugged session duration.
Connector seats flat into the battery slot with single locking tab — no force needed.
We bench-tested discharge under sustained CPU and GPU load; BMS held voltage stable until final 5%.
After installation, run one complete 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.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Blade Pro shutting down at 20–30% shown after battery swap

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.

Frequently Asked Questions

My Razer Blade Pro shows "plugged in, not charging" and stops at 80% — is the replacement battery faulty?

This is almost always a BIOS-controlled charge limit, not a battery fault. Razer's firmware includes a charging threshold setting that caps charge at 80% to reduce long-term cell stress — it ships enabled on some units and can be toggled on accidentally. Open Razer Synapse, go to Power, and check the Battery Saver or Charging Threshold setting. Disable it, unplug and reconnect the charger, and the cell will charge to 100%.

Windows says the new battery's health is "poor" or capacity is listed as much lower than 69.54Wh — what's happening?

Windows reads battery health from EEPROM data the cell writes to the EC on first contact. With a new replacement cell, the EC hasn't yet completed a learn cycle against the new chemistry, so it reports degraded or mismatched health figures. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100% without interruption. After that cycle completes, the EC recalculates full charge capacity and the health report corrects itself.

The fuel gauge on my Blade Pro 17 jumps erratically — showing 60%, then 45%, then back to 55% within minutes — after fitting the RC30-0220.

The fuel gauge IC uses a discharge model built around the original cell's chemistry profile. A new cell has a different internal resistance curve, so the IC's state-of-charge estimates are unstable until it collects enough data. This settles after two to three full discharge-charge cycles under real workload — gaming or video rendering works better than idle use because it draws enough current for the IC to map the new cell's voltage response accurately. After three cycles, the gauge typically stabilises to within 3–5%.
