Fits Gigabyte P35X V6-PC4K4D and 30+ compatible models, replaces OEM part GNS-160 or GNS-I60.
11.1V, 6600mAh Li-Polymer delivers 73.26Wh capacity for extended unplugged operation on this gaming notebook.
Connector seats flush into the Gigabyte mainboard slot with side-release locking tab; no adapter needed.
We bench-tested this cell against P35X V6 firmware; BMS initialized without errors and held 11.1V under sustained CPU load.
After installation, discharge the laptop fully to hibernation, then charge uninterrupted to 100% — this resets the BIOS fuel gauge IC and clears the false low-health warning that appears after every cell swap.

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.

Gigabyte P35X V6-PC4K4D / P57X V7 — 11.1V Li-Polymer Replacement Battery (GNS-160)

This is an 11.1V, 6600mAh (73.26Wh) Li-Polymer replacement battery for the Gigabyte P35X V6-PC4K4D gaming laptop and compatible P35/P57 series notebooks. It slots directly into the same bay as the original GNS-160 pack. The OEM part number GNS-I60 is an alternate label for the same cell configuration.

  • P35X V6 and P57X V7 platform fit: These two chassis share the same 11.1V three-cell battery bay, connector pinout, and BMS handshake protocol — so one cell pack covers both. The P35K-965-4702S and P35X V7 use the same arrangement.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on P35X V6 hardware. The BMS handshake completed correctly, the BIOS recognised the pack without prompts, and charge termination triggered cleanly at full voltage.
  • First-cycle calibration on the P35X V6: After installing, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. 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 on this platform.

Why the P35X V6 shuts down at 20–30% charge shown after a battery swap

The P35X V6 runs a combined CPU and discrete GPU load that can spike current draw well above what the fuel gauge IC expects from a new, uncalibrated cell. When the voltage drops faster than the IC predicts under that load, the BMS trips a low-voltage cutoff before the display percentage hits zero. The shutdown is not a faulty cell — it is the fuel gauge reading from stale EEPROM data carried over from the old pack. Running two full discharge-to-hibernate and uninterrupted recharge cycles resolves this in most cases. After calibration, cutoff should align with a real terminal voltage of approximately 9V across the pack.

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

The Gigabyte P35X BIOS reads health status from EEPROM data written by the original cell during its service life. A new cell arrives with a blank or default EEPROM state, so the BIOS flags it as degraded before any cycles have run. This is a firmware read issue, not a defect in the replacement pack. Run the full discharge-and-recharge calibration cycle described above — most P35X units clear the health warning after one complete cycle and update the EEPROM with fresh charge data from the new cell.

Frequently Asked Questions

My Gigabyte P35X V6 shows the replacement battery at 0% or won't detect it at all in Windows — what's wrong?

Windows is reading stale fuel gauge IC data that doesn't match the new cell's chemistry profile. The OS fuel gauge needs at least one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% before it can accurately track the new pack. Until that cycle completes, Windows will report 0%, unknown, or jump erratically between percentages. Run that calibration cycle once, then check Device Manager under Batteries — the pack should register correctly.

The system info screen shows a different Wh rating than the 73.26Wh spec on the listing — is the battery wrong?

The Wh figure Windows or the BIOS displays comes from the EEPROM embedded in the battery controller, not from a live measurement of the cell. A fresh replacement cell often ships with a default or nominal EEPROM value that doesn't match the rated spec until the BMS has completed a full charge cycle and written updated data. This is an EEPROM initialisation difference, not a capacity mismatch. Charge the pack fully, discharge it once, then recharge — the reported Wh figure should align with the rated 73.26Wh after the first completed cycle.

The P35X V6 is plugged in and charging, but the charge stops and won't go above 80% — is this a faulty cell?

The P35X platform includes a BIOS-level charge limit that caps charging at 80% when Battery Life Saver or a similar firmware setting is active. This is not a cell fault — the battery is working correctly and the BMS has received a charge-limit instruction from the BIOS. Go into the Gigabyte Smart Manager software or the BIOS power settings and disable the charge limit or switch the mode to full charge. Once disabled, the pack will charge to 100%.
