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 N750 Series — 11.1V Li-Polymer Replacement Battery (C32-N750)

This is a 11.1V, 6250mAh Li-Polymer replacement battery for the Asus N750 series notebook. It fits models including the N750JK, N750JV, and N750Y47JV-SL. OEM part references are C32-N750 and 0B200-00400000.

  • N750 series compatibility: The N750JK, N750JV, and related variants share the same 11.1V three-cell Li-Polymer pack format, connector pinout, and BMS communication protocol — which is why a single cell services the entire line without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and load on the N750 platform. The BMS handshake completed correctly, charge current stepped down at the expected threshold, and the protection circuit tripped at the rated low-voltage cutoff under sustained CPU and GPU load.
  • First-cycle calibration on the N750: After fitting this cell, run the laptop unplugged until it reaches hibernate cutoff, then charge uninterrupted to 100% without interruption. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting battery health as poor immediately after fitting a new cell

The N750's BIOS stores charge history and wear data from the previous cell in a learn register. When a new cell goes in, that register still holds degraded-cell data, so the firmware flags poor health even though the cell is new. This is not a battery fault — it is a calibration mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle. After two or three full cycles, the BIOS health reading will accurately reflect the new cell.

Laptop shuts down abruptly while the OS gauge still shows 20–25% remaining

This happens when the fuel gauge IC's stored charge map no longer matches the new cell's actual discharge curve. Under combined CPU and display load, the cell voltage drops faster than the IC predicts, hitting the hardware cutoff while the OS still shows charge remaining. The fix is cell calibration: drain fully to hibernate, then charge to 100% without pausing. Repeat this two to three times until the OS percentage and the actual cutoff point align — the gauge IC recalculates its map against the new cell's voltage slope each cycle.

Frequently Asked Questions

Why does my N750 show "plugged in, not charging" and stop at exactly 80% after fitting this battery?

The N750 BIOS includes a charge limit setting — often enabled by default or carried over from the previous battery profile — that caps charging at 80% to reduce cell stress during long plugged-in use. This is a firmware control, not a fault with the replacement cell. Go into the Asus Battery Health Charging utility (or MyASUS app) and switch the mode to Full Capacity Mode. The battery will then charge to 100%.

Windows is showing the wrong Wh rating in Device Manager after fitting the new cell — it still shows my old battery's capacity. How do I fix this?

The Wh figure Windows displays is read from the EEPROM on the battery's BMS, not calculated live from the cell. After a cell swap, the OS can briefly cache the old battery's EEPROM data until the learn cycle refreshes it. Run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. After the cycle completes, Windows should report 69.38Wh, matching the new cell. If it still shows the old value, a full shutdown and cold boot clears the cached reading.

The N750 fuel gauge jumps erratically — dropping from 60% to 30% in minutes, then recovering. What is causing this?

The fuel gauge IC on the N750 uses a charge map built from previous cell data to estimate remaining capacity. A new cell has a different discharge curve, so the IC's predictions are inaccurate until it recalibrates. The erratic jumps are the IC correcting itself mid-discharge as it reads voltage data that does not match its stored map. Run two to three full discharge-to-hibernate and uninterrupted full-charge cycles. The IC rebuilds its curve from measured data each cycle, and the gauge stabilises once it has enough real readings — typically by the third cycle.
