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 UX530UQ / UX430UA Series — 11.55V Li-Polymer Replacement Battery (C31N1622)

This is an 11.55V, 4200mAh (48.51Wh) Li-Polymer battery for the Asus VivoBook Pro UX530UQ-FY058R and a wide range of UX530 and UX430 Zenbook models. It replaces OEM part numbers C31N1622, 0B200-02390000, 0B200-02390200, 0B200-02390300, and 31CP5/70/81. If your original cell has degraded or stopped holding charge, this is the direct cell swap.

  • UX530 and UX430 platform compatibility: These models share the same three-cell Li-Polymer pack layout, 11.55V voltage rail, and BMS handshake protocol. One part number — C31N1622 — covers the full range because the connector pinout and charge controller communication are identical across these chassis revisions.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on UX530-series hardware. The BMS negotiated correctly with the EC, charge termination triggered at the expected cutoff voltage, and cell balancing across all three cells stayed within tolerance throughout.
  • Post-install calibration on the UX530: After fitting this cell, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting battery health as poor after replacement on the UX530

The UX530's embedded controller reads health data from EEPROM registers built into the original battery pack. When a new cell goes in, those registers report different values than what the EC cached from the old unit. The BIOS flags this mismatch as "poor health" or "not installed correctly" even when the new cell is working perfectly. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% prompts the EC to rewrite its cached values against the new cell. After two to three full cycles, health reporting normalises.

UX530 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC loses calibration against the new cell's actual voltage curve. The gauge estimates remaining capacity based on a table built from the old cell — when the new cell's voltage drops under combined CPU and display load, it hits the low-voltage cutoff before the gauge reaches 0%. The laptop cuts power to protect the cell even though the percentage shown still looks safe. Fix this by running two to three full discharge-to-hibernate cycles so the fuel gauge IC relearns the new cell's actual voltage cliff — which typically occurs around 10.2V under load on this pack.

Frequently Asked Questions

Why does my Asus UX530 show the battery as "unknown" or 0% immediately after fitting the new cell?

The embedded controller on the UX530 reads identity and health data from the old cell's EEPROM. A fresh cell presents different register values, so the EC reports "unknown" until it completes a learn cycle. Plug in the charger and let it charge uninterrupted to 100%, then do one full discharge to hibernate — this forces the EC to write new baseline values. After that cycle, the percentage and health status report correctly.

My UX530 shows 48Wh in Windows but the BIOS system info shows a different Wh figure — which is correct?

The figure shown in BIOS is pulled from the EEPROM of the battery pack, which stores the rated Wh from the original cell's firmware. The Windows reading reflects actual measured capacity from the charge controller after calibration. After two to three full discharge and charge cycles, the Windows figure settles to the true capacity of the new cell — 48.51Wh at full charge. The BIOS figure may lag or differ slightly; that is an EEPROM data artefact, not a fault with the cell.

The charge stops at around 80% and won't go higher — is the new battery faulty?

Almost certainly not. Asus BIOS on the UX530 platform includes a battery charge limit feature, sometimes called "Battery Health Charging," that caps charge at 60% or 80% to reduce long-term wear on cells used mostly on AC power. Check the MyASUS application or BIOS under Advanced settings and set the charge mode to "Full Capacity." Once switched, the next charge cycle will reach 100%.
