Battery Care Tips
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
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.

Compal GL30 / GL31 Series — 11.1V Li-ion Replacement Battery (90-NFY6B1000Z)
This 11.1V, 6600mAh Li-ion battery replaces the original cell in Asus GL30, GL31, EL80, and EL81 notebook computers. It matches the OEM voltage rail and connector pinout for these platforms. Capacity is 6600mAh (73.26Wh) — use the product data figure, not the sticker on the old cell.
- GL30 / GL31 / EL80 / EL81 platform fit: These models share a common battery bay dimension (205 × 69 × 20mm), the same 11.1V three-cell voltage rail, and identical BMS communication pins. One cell covers all four platforms without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on GL30 and GL31 units. The BMS handshake completed on first connection, charge acceptance started immediately, and the protection circuit tripped correctly at both over-voltage and undervoltage thresholds.
- First-cycle calibration on the GL30: After fitting, run the laptop on battery until it hibernates at low charge cutoff — do not interrupt. 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 GL30 BIOS flags a new battery as poor health immediately after swap
The GL30 BIOS stores battery health data in EEPROM tied to the original cell's charge history. When a new cell connects, the EEPROM data does not match the cell's actual state, so the BIOS reports degraded health before any real measurement occurs. This is a firmware artefact, not a cell defect. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the fuel gauge IC to re-learn the new cell's capacity curve and clears the false health flag.
GL30 shutting down at 20–30% charge shown on the OS gauge
This happens when the fuel gauge IC has not yet calibrated against the new cell — the percentage shown is still mapped to the old cell's degraded voltage curve. Under full CPU and display load, the new cell's actual voltage drops faster than the gauge expects, hitting the BMS undervoltage cutoff while the OS still displays 20–30%. The fix is two to three full discharge and charge cycles without interruption. After calibration, the gauge tracks correctly and the early shutdowns stop.

Frequently Asked Questions
My GL30 shows the battery as 0% or "unknown" right after I installed the new cell — is it dead?
The fuel gauge IC on the GL30 still holds calibration data from the old cell, so it cannot map the new cell's voltage curve until it runs a learn cycle. The battery is not dead. Charge it fully to 100% uninterrupted, then discharge to hibernate cutoff without plugging in. After one or two full cycles the OS gauge will lock onto the correct readings and the "unknown" or 0% reading clears.
Windows reports this battery's Wh rating as different from the 73.26Wh listed — why does the number not match?
The Wh figure Windows reads comes from the EEPROM data embedded in the battery's BMS chip, which stores the rated design capacity from the cell manufacturer. The 73.26Wh in the product listing is the actual measured energy capacity of this cell. These two numbers can differ by a small margin because EEPROM stores nominal chemistry ratings, not bench-measured output. The discrepancy is normal and does not affect charge behaviour or discharge performance.
The GL30 charges to around 80% then stops — is the charger or the battery at fault?
Neither. The GL30 BIOS includes a charge limit setting that caps charging at 80% when battery care or eco-charge mode is enabled in the firmware. Check the BIOS power settings or the Asus battery care utility in Windows and disable the charge limit. Once turned off, the next charge cycle will proceed past 80% and reach 100%.
