LG P430 Laptop Replacement Battery 11.1V 5200mAh EAC61679004

Up to 19% off
New arrival
From $81.99 USD $100.99
Shipping calculated at checkout.
Fits LG P430, P530, Xnote models; replaces OEM part numbers EAC61679004, GC02001H400, LB3211LK, LB6211LK.
11.1V, 5200mAh lithium-ion cell delivers 57.72Wh to sustain full CPU and display load on the P430 platform without early shutdown.
Connector slides into the battery slot with a single locking tab on the left side; orientation is fixed by the keyed housing.
We ran a full discharge-to-cutoff cycle followed by continuous charge to 100%; the BMS engaged protection thresholds at spec with no fault codes.
After installation, run one full discharge to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after cell swaps.

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.

LG P430 / P530 Xnote Series — 11.1V Li-ion Replacement Battery (EAC61679004)

This is a 11.1V, 5200mAh (57.72Wh) Li-ion battery for the LG Xnote P430 and P530 laptops. It cross-references OEM part numbers EAC61679004, GC02001H400, LB3211LK, and LB6211LK. If your original battery no longer holds a charge or the laptop dies under load, this cell is the direct swap.

  • P430 and P530 platform fit: Both notebooks share the same battery bay geometry, connector pinout, and BMS handshake protocol — that is why a single cell covers both. The EEPROM in this battery carries the correct Wh rating so the LG BIOS recognises it without flags.
  • Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on a P430 chassis. The BMS communicated correctly, the BIOS reported accurate state-of-charge, and no protection cutoff triggered during sustained CPU and display load.
  • Post-install calibration for Xnote P-series: After fitting this battery, run the laptop on battery power until it hibernates at low charge, then charge uninterrupted to 100% without interruption. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after fitting a new cell

The LG Xnote BIOS reads health data from the battery's EEPROM, not from live cell voltage. When you swap cells, the BIOS compares the new cell's EEPROM data against the discharge history stored from the old battery. The mismatch triggers a "poor health" or "replace battery" flag even though the new cell is fully functional. One complete discharge-to-hibernate followed by an uninterrupted full charge clears the stored history and resets the learn cycle correctly.

Laptop shuts down abruptly when the fuel gauge still shows 20–30%

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual capacity curve. The IC uses stored data from the old, degraded cell to predict the voltage cliff, so it underestimates how quickly the new cell will drop under combined CPU and display load. The result is a sudden shutdown that looks like a fault but is actually a calibration gap. Run two full discharge-to-hibernate and full-recharge cycles — after the second cycle the gauge IC recalibrates and the remaining percentage readings stabilise.

Frequently Asked Questions

My LG Xnote P430 shows 0% or "unknown" battery right after I installed the new cell — is the battery faulty?

It is not a faulty cell. The LG BIOS reads identity and capacity data from the battery's EEPROM, and on first install it has no discharge history to reference, so it reports 0% or unknown until the learn cycle runs. Charge the battery to 100% uninterrupted, then discharge on battery power until the laptop hibernates. After one complete cycle, the BIOS will report an accurate state-of-charge.

The system info screen shows a lower Wh rating than the 57.72Wh spec — why does the number not match?

The Wh figure shown in Windows or in BIOS setup is pulled from the EEPROM on the battery cell, and the rated value stored there reflects factory cell chemistry tolerances, not a measured real-time reading. A small variance between the EEPROM figure and the label spec is normal across Li-ion cells. If the displayed value is within a few Wh of 57.72Wh, the cell is reporting correctly — no action needed. If the figure is dramatically lower, reseat the battery connector and re-read after a full charge cycle.

The P530 charges fine but the fuel gauge jumps around wildly — showing 80%, then 45%, then 70% within minutes.

The fuel gauge IC on the P530 motherboard calibrates itself against the actual discharge curve of the installed cell over the first few cycles. When a new cell goes in, the IC is still using the old cell's curve data, which causes erratic percentage readings. This is not a defect in the replacement battery. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100%, and the gauge IC will lock onto the new cell's curve — readings will stabilise after the second cycle.
