Asus FE375CG Replacement Battery C11P1402 3.8V 3900mAh

Up to 20% off
New arrival
From $27.99 USD $34.99
Shipping calculated at checkout.
Fits Asus FE375CG, FE375CXG, Padphone 7 K019, and ME375C tablets; replaces OEM part C11P1402.
3.8V and 3900mAh capacity matches the original cell; delivers 14.82Wh to sustain the display and WiFi during normal daily use.
Connector slides straight into the battery slot with a locking tab on the left edge; orientation marked on the housing matches the tablet bay.
We ran full discharge and recharge cycles on the FE375CG platform; the BMS accepted the new cell without fault codes or voltage rail anomalies.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell and resolves the inaccurate percentage display that appears after a swap.

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 FE375CG / FE375CXG Series — 3.8V Li-Polymer Replacement Battery (C11P1402)

This is a 3.8V, 3900mAh (14.82Wh) Li-Polymer battery for the Asus FE375CG, FE375CXG, Fonepad 7 K019, and ME375C tablets. It replaces OEM part number C11P1402. If your tablet no longer holds a charge or shuts down unexpectedly, this is the direct swap.

  • FE375 platform fit: The FE375CG and FE375CXG share the same 3.8V battery rail, connector pinout, and BMS handshake protocol. The ME375C and Fonepad 7 K019 use the same cell footprint. One part number covers all four.
  • Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence on the FE375CG. The BMS accepted the charge handshake without fault codes, and the protection circuit responded correctly at both low-voltage and over-current thresholds.
  • Fuel gauge recalibration after swap: After installing this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without unplugging. This single cycle resets the fuel gauge IC against the new cell and clears the inaccurate percentage reading that almost always appears after a battery replacement.

Why the FE375CG shuts down at 15–25% remaining

The FE375CG runs a display and simultaneous WiFi load that pulls a combined current spike the aging cell can't sustain at lower state-of-charge. Voltage drops below the BMS cutoff threshold before the fuel gauge reads zero — so the tablet cuts power while the percentage still shows double digits. A new cell with full capacity handles that combined draw without the voltage cliff. After fitting this battery, run the recalibration cycle above so the fuel gauge maps the new cell's actual discharge curve.

Fast charging not available after fitting a new battery

Some FE375CG units revert to standard 5V charging after a battery swap and won't re-enter the faster charge mode on the first plug-in. This happens because the charge IC resets its negotiation state when the battery connection is broken. Plug in the original charger and let the tablet complete one full charge cycle without interruption. After that cycle completes and the indicator hits 100%, the charge IC re-establishes the correct negotiation and faster input resumes on subsequent charges.

Frequently Asked Questions

My FE375CG is showing the wrong battery percentage after fitting the new battery — is something wrong with it?

Nothing is wrong with the battery. The fuel gauge IC on the FE375CG was calibrated to the discharge curve of the old, degraded cell, so it misreads the new one. Run the tablet down to automatic shutoff, then charge it uninterrupted to 100%. That single full cycle re-anchors the gauge against the new cell's actual capacity curve and the percentage reading corrects itself.

The tablet feels warm near the charging port while charging after the battery swap — should I be concerned?

Mild warmth during the first few charge cycles is normal. The charge IC on the FE375CG applies a conditioning current to a newly connected cell, which generates slightly more heat than a settled battery accepts. If the warmth is concentrated at the back panel near the cell rather than the port, and the tablet is not hot to the touch, no action is needed. If surface temperature feels excessive, disconnect and check that the connector is fully seated — a partial connection forces higher resistance and more heat.

My FE375CG percentage drops fast from 100% but then slows down — why is it uneven across the charge range?

This is fuel gauge drift, not a cell fault. The gauge IC on the FE375 interpolates state-of-charge from a stored discharge curve, and after a battery swap that stored curve no longer matches the new cell. The mismatch causes the percentage to appear to drop quickly at the top of the range and then slow mid-cycle. Run one complete discharge to automatic shutoff followed by an uninterrupted charge to 100% — this recalibrates the stored curve against the installed cell and the percentage steps evenly across the full range.
