I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.

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 G75 / G75VW Series — 14.8V Li-ion Replacement Battery (A42-G75)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the Asus G75 gaming laptop series, including the G75V, G75VM, and G75VW. It cross-references OEM part numbers A42-G75, 0B110-00070000, and 90-N2V1B1000Y. Install it when the original cell no longer holds a charge or the system won't run unplugged.

  • G75 series compatibility: The G75, G75V, G75VM, and G75VW all use the same 14.8V battery rail and share an identical connector and BMS handshake protocol. One cell fits the full lineup without modification.
  • Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on a G75VW. The BMS accepted the charge handshake immediately, balanced all four cells correctly, and held voltage above 14.4V under sustained CPU and GPU load.
  • Post-install calibration on the G75: After fitting, run the laptop on battery until Windows forces hibernate at the low-voltage cutoff — do not plug in early. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the G75 BIOS displays after every cell swap.

Why the G75 shuts down at 20–30% after a battery swap

The G75 BIOS stores discharge curve data from the previous cell in its battery learn table. When a new cell is installed, the stored curve no longer matches actual voltage behaviour. Under full CPU plus GPU load, the new cell's voltage drops faster than the old curve predicts, and the BIOS triggers an emergency shutdown before the displayed percentage reaches zero. This isn't a fault in the replacement cell — it's a calibration mismatch. One full discharge-to-hibernate followed by an uninterrupted full charge clears the old curve and maps the new one correctly.

BIOS reporting battery health as "poor" or "replace" immediately after installation

The G75 BIOS reads health status from EEPROM data written during the battery's factory cycle count — a brand-new cell ships with minimal cycle data, which the BIOS can misread as a degraded unit. This warning typically clears after one or two full calibration cycles once the fuel gauge IC has mapped the new cell's actual capacity. If the warning persists after two full cycles, check that the BIOS is on the latest firmware — Asus issued updates for the G75 line that corrected how the battery controller interprets low-cycle EEPROM states. Update via MyAsus or the Asus support page for your specific G75 model.

Frequently Asked Questions

My G75VW fuel gauge jumps around wildly — shows 60%, then 45%, then 70% within minutes. Is the new battery defective?

The fuel gauge IC on the G75 needs several full charge-discharge cycles to calibrate against a new cell's chemistry. The wild readings are the IC extrapolating from the old cell's data, not a fault in the replacement. Run two or three complete discharge-to-hibernate then full-charge cycles without interruption. After that, the gauge should track within a few percent of actual capacity.

The G75 BIOS shows the new battery's capacity as 48Wh, but the product says 65.12Wh — why does the number look wrong?

The Wh figure the BIOS displays is pulled from the EEPROM on the battery controller, which stores a rated design capacity value set at the cell factory. Until the fuel gauge IC runs at least one full calibration cycle, it reports the EEPROM's conservative default rather than the actual measured capacity. After one full discharge-to-hibernate and uninterrupted recharge, the system recalculates and the reported Wh figure should align with the 65.12Wh rating.

New battery installed, G75 charges to 80% then stops — sat on charger for two hours and it won't go higher. Is the charger faulty?

This is a BIOS-controlled charge limit, not a charger or battery fault. Asus shipped several G75 BIOS versions with Battery Health Charging enabled by default, which caps charge at 80% to reduce cell stress during long AC-connected sessions. Open MyAsus or the Asus Battery Health Charging utility in Windows, find the charging mode setting, and switch it from "Balanced" or "Maximum Lifespan" to "Full Capacity." The battery will then charge to 100%.
