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.

Asus M50 / N61 / X64 Series — 11.1V Li-ion Replacement Battery (A32-M50)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for Asus M50, M51, M50S, M50Q, N61, X64, and related notebook series. It replaces OEM part A32-M50 and cross-references including A32-N61 and A32-X64. If your original cell no longer holds charge or the laptop shuts down unexpectedly on battery, this is the direct cell swap.
- M50, N61, and X64 platform compatibility: These three Asus notebook lines share the same 11.1V three-cell-series architecture, identical connector pinout, and compatible BMS communication protocol — which is why one cell part number spans all of them. Voltage rails and charge termination logic match across the group.
- Bench tested on actual hardware: We cycled this cell through charge, full-load discharge, and BMS fault recovery. The protection circuit tripped correctly at low-voltage cutoff and recovered cleanly on reconnect. Charge termination at 12.6V was within spec across multiple runs.
- Post-install calibration on Asus M-series: After installing, run one full discharge until the laptop hibernates on its own, 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 Asus M50 shuts down at 20–30% shown on the fuel gauge
The fuel gauge IC on the M50 platform was calibrated against the original cell's discharge curve. A new cell has a slightly different voltage-versus-capacity slope, so the IC reads 25% remaining while the actual terminal voltage has already dropped below the CPU-plus-display load floor. Under full load — backlit screen, active processor — voltage collapses faster than the gauge predicts. Run two full discharge-to-hibernate cycles back-to-back and the gauge IC re-learns the new curve, pushing the shutoff point down to where it belongs.
BIOS reporting poor battery health or "unknown" immediately after swap
The Asus BIOS reads health status from EEPROM data embedded in the battery's BMS — not from measured capacity. A new cell ships with factory EEPROM values that don't match the learned data the BIOS stored for the old cell, so it flags the status as degraded or unknown. This is not a fault with the replacement cell. Complete one full discharge-to-hibernate cycle followed by a full uninterrupted charge to 100%, and the BIOS will rewrite its stored health baseline against the new cell's data.

Frequently Asked Questions
My Asus M50 shuts off suddenly under load but shows 25% battery left — is the new cell faulty?
The cell is not faulty. The fuel gauge IC was calibrated against your original cell's discharge curve, and the new cell has a different voltage slope under load. When the CPU and display draw peaks, terminal voltage drops faster than the gauge predicts, triggering an emergency shutoff. Run two complete discharge-to-hibernate cycles and the gauge IC will re-learn the new curve against actual measured voltage.
Windows is showing the replacement battery's capacity as lower than the rated 48.84Wh — why does the Wh figure look wrong in system info?
The Wh figure Windows reports is read from the EEPROM inside the battery's BMS, not measured live. The factory EEPROM value on a new cell may differ slightly from the rated spec until the BIOS completes a full learn cycle. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%, and the system will overwrite the stored Wh figure with a measured value that matches the actual cell chemistry.
The replacement battery isn't charging above 80% on my Asus laptop — is the charge limit stuck?
Asus BIOS on several M-series and N-series models includes a charge-limit feature that caps charging at 80% to reduce cell wear — it's a firmware setting, not a battery fault. Check the Asus Battery Health Charging utility in Windows; if it's set to "Balanced" or "Maximum Lifespan" mode, it intentionally holds the charge ceiling at 80%. Switch the mode to "Full Capacity" and the battery will charge to 100%.
