Asus ProArt StudioBook Pro X C32N1838 Replacement Battery 11.48V 8000mAh

Up to 18% off
New arrival
From $127.99 USD $154.99
Shipping calculated at checkout.
Fits Asus ProArt StudioBook Pro X W730G5T-H8052R and related models, replacing OEM part C32N1838 and 0B200-03460100.
Delivers 11.48V at 8000mAh capacity, matching the original Li-Polymer cell for full workstation performance without voltage sag under GPU and CPU load.
Connector type is proprietary Asus barrel with keyed alignment; locking tab seats flush against the battery compartment frame on insertion.
We bench-tested this cell through five full charge cycles on the W730 platform — the BMS regulated output cleanly to 11.48V nominal, and BIOS recognized the new pack within two minutes of first connection.
After installation, run one full discharge to system hibernation, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Asus ProArt StudioBook Pro X W730G5T Series — 11.48V Li-Polymer Replacement Battery (C32N1838)

This is an 11.48V, 8000mAh (91.84Wh) Li-Polymer battery for the Asus ProArt StudioBook Pro X W730G5T series. It fits the W730G5T-H8052R, W730G5T-H8050T, W730G5T-AV011T, W730G5T-AV009T, and over 20 additional W730G5T variants. OEM part numbers covered are C32N1838 and 0B200-03460100.

  • W730G5T platform compatibility: Every W730G5T variant shares the same voltage rail, connector pinout, and BMS handshake protocol. The StudioBook Pro X uses a 3-cell Li-Polymer configuration with an EEPROM-coded BMS — any cell carrying C32N1838 talks to the BIOS without modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a W730G5T unit. The BMS reported state of charge accurately across the range, and the BIOS accepted the cell without throwing an unknown battery warning on the first boot.
  • First-cycle recalibration on the W730G5T: After installing, run one full discharge down 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 this platform.

Why the W730G5T BIOS flags a new cell as poor health

The StudioBook Pro X stores battery health data in the EEPROM of the original cell. When you swap in a new cell, the BIOS compares current readings against that saved baseline and flags a mismatch as degraded health. This is a calibration gap, not a fault with the replacement cell. Running one full discharge-to-hibernate then a continuous charge to 100% rewrites the learn cycle data. After one or two full cycles, the BIOS health reading normalises.

Laptop shuts down at 20–30% after battery swap

This happens because the fuel gauge IC is still reading from the old cell's discharge curve. Under full CPU and display load, the W730G5T draws enough current to cause a rapid voltage drop in the new cell — the uncalibrated gauge hits its cutoff threshold early and triggers shutdown. The fix is forcing the fuel gauge IC to recalibrate: discharge to hibernate-cutoff under real load, not idle, then charge to 100% without interruption. After two full cycles under load, the gauge tracks accurately and the early shutdowns stop.

Frequently Asked Questions

My W730G5T is showing 0% and "plugged in, not charging" right after I installed the new battery — what's wrong?

The EEPROM in the new cell holds rated data that doesn't match the old cell's stored baseline, so the BIOS reads the state of charge as unknown and refuses to begin a charge cycle. Disconnect the AC adapter, hold the power button for 15 seconds to clear any residual charge in the system, then reconnect AC and power on. The BIOS should re-initialise the fuel gauge IC and begin charging — watch for the battery indicator to move above 0% within two minutes of reconnecting power.

The Wh rating shown in Windows Battery Report is wrong after swapping the cell — it says 72Wh instead of 91.84Wh. Is the battery faulty?

The Windows Battery Report reads the designed capacity value stored in the cell's EEPROM, which can differ from the actual chemistry capacity until the fuel gauge IC runs a full calibration cycle. The cell itself is not faulty — the rated 91.84Wh figure matches the C32N1838 spec. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100%, then regenerate the Battery Report. The figure should update to reflect the correct 91.84Wh after the fuel gauge IC writes its first complete cycle log.

The fuel gauge on my StudioBook Pro X is jumping erratically — it reads 60%, then skips to 85%, then drops to 40% within minutes. How do I fix this?

The fuel gauge IC on the W730G5T uses the discharge curve from the previous cell to estimate charge level. A new Li-Polymer cell has a slightly different internal resistance profile, so the IC loses tracking accuracy and produces erratic jumps. This is not a hardware fault — the IC needs two to three full calibration cycles against the new cell's actual curve. Discharge under real workload to hibernate-cutoff, then charge uninterrupted to 100%, and repeat twice. After the third cycle, the gauge reads from a corrected curve and the erratic jumps stop.
