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.

LG E500 — 11.1V Li-ion Replacement Battery (90-NFY6B1000Z)

This is an 11.1V, 6600mAh Li-ion replacement battery for the LG E500 notebook. It replaces a degraded or failed original cell and restores portable operation to the machine. Capacity is rated at 73.26Wh, matching the original specification.

  • E500 platform compatibility: The E500 shares its battery bay dimensions and connector pinout across several LG notebook variants. Cross-reference OEM part numbers — including SQU-503, A32-F3, and BATEL80L6 — to confirm the right fit before installation. This battery covers that full group.
  • Bench tested on actual hardware: We ran this cell through a full charge and discharge cycle on E500-class hardware. The BMS communicated correctly with the system, charge acceptance was normal, and the fuel gauge IC registered cell voltage without error.
  • Post-install calibration cycle: After fitting this battery, run the laptop on battery power until it hibernates at cutoff — do not interrupt. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after any cell swap on this platform.

BIOS reporting poor battery health immediately after replacement

The E500 BIOS reads health data from EEPROM stored on the battery's BMS board. When a new cell goes in, the BIOS compares accumulated cycle data — which is blank — against its internal thresholds and flags it as unknown or degraded. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the fuel gauge IC to write calibrated data back to the BIOS. After two to three cycles the health status updates and the warning clears.

Laptop shuts down at 20–30% shown on the fuel gauge

This is a voltage cliff issue, not a fuel gauge miscalibration. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track, and the BMS cuts power before the displayed percentage reaches zero. It appears most often in the first few cycles when the fuel gauge has not yet mapped the new cell's discharge curve. Run two full discharge-to-hibernate cycles with the display at full brightness and a CPU load running to force the IC to recalibrate its low-voltage cutoff model. After calibration the shutdown threshold should stabilise at or below 5% displayed.

Frequently Asked Questions

Why does my LG E500 show 0% or "unknown" battery right after I put the new one in?

The BIOS pulls health data from the EEPROM on the battery's BMS board. A new cell has no accumulated cycle data, so the BIOS flags it as unknown or reports 0%. Run a full discharge to hibernate-cutoff, then charge uninterrupted to 100% — this writes fresh calibration data to the EEPROM and the reading corrects within two cycles.

My E500 fuel gauge is jumping around wildly — shows 60%, then 45%, then 70% within minutes. What's happening?

The fuel gauge IC maps its estimates against discharge data from the previous cell. With a new cell installed, that mapping is wrong and the gauge swings until it builds a new reference curve. This is normal for the first two to three cycles. Run the battery down to hibernate cutoff twice under real load — display on, active use — and the gauge will stabilise.

The replacement battery shows the wrong Wh rating in Windows system info — 47Wh instead of 73Wh. Is the cell faulty?

The Wh figure Windows reads comes from a static value stored in the battery's EEPROM, not from live cell measurement. If the EEPROM from a different OEM part number is present, the reported Wh will not match the physical cell. The actual delivered capacity is 73.26Wh — confirm this by running a full discharge cycle and checking the energy counter in a tool like HWiNFO64 or BatteryInfoView rather than relying on the Windows system info field.
