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 450 / 450C / 450V Series — 10.8V Li-ion Replacement Battery (A32N1331)
This is a 10.8V, 4800mAh Li-ion battery pack for the Asus 450, 450C, 450CD, and 450V series notebooks. It replaces OEM part numbers A32N1331, A32N1332, and the 0B110-00280000 family. Install it when the original cell no longer holds a usable charge or fails to power the laptop off the mains.
- 450-series platform fit: The 450, 450C, 450CD, and 450V share the same battery bay geometry, connector pinout, and BMS handshake protocol — which is why a single cell covers all these variants. Voltage rail is 10.8V across the board.
- Bench tested on actual hardware: We ran this cell through full charge and load cycles on an Asus 450-series unit. The BMS communicated correctly with the EC, charge acceptance hit rated capacity, and the protection circuit tripped at the expected low-voltage threshold without a hard crash.
- Post-install calibration on Asus 450 series: After fitting, run the laptop down to hibernate cutoff under normal use — do not force-shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.
Why the Asus 450 shuts down at 20–30% after a battery swap
A new cell has different internal resistance characteristics than the aged cell the fuel gauge IC was calibrated against. Under full CPU and display load, voltage sags faster than the IC predicts — and the laptop hits the EC's low-voltage cutoff while the gauge still reads 20–30%. This is not a fault in the replacement cell. Running two or three full discharge-to-hibernate and full-charge cycles gives the fuel gauge IC enough data to recalibrate against the new cell's actual discharge curve. After calibration, the gauge and the real remaining capacity realign.
BIOS showing 0% or "Unknown" battery immediately after install
The BIOS reads health and state-of-charge data from the battery's EEPROM on first contact. A new cell ships with EEPROM counters at factory defaults, which the Asus EC can misread as an unrecognised or failed pack. Boot into Windows and let the battery manager initialise — this usually resolves within the first full charge cycle. If the BIOS still reports unknown after one full charge, enter the BIOS setup, navigate to the battery information screen, and save-exit to force a re-read of the pack's EEPROM. Target a full charge to 10.8V before checking again.

Frequently Asked Questions
Why does my Asus 450 still show "poor battery health" in the BIOS after fitting a new cell?
The BIOS pulls health data from the battery's EEPROM, and a replacement cell ships with factory-default counters that the Asus EC flags as degraded. This is an EEPROM data mismatch, not a fault in the new battery. Run one complete discharge to hibernate cutoff, then charge uninterrupted to 100% — this triggers the BIOS battery learn cycle and overwrites the stale health data. After that cycle, re-enter BIOS setup and the health status should clear.
The fuel gauge jumps around wildly for the first few days — is something wrong with the replacement cell?
Nothing is wrong. The fuel gauge IC was calibrated against the old cell's discharge curve, and the new cell has different impedance characteristics. Until the IC collects enough charge and discharge data to recalibrate, it estimates state-of-charge inaccurately. Run two to three full discharge-to-hibernate and full-charge cycles under normal laptop use — not fast-discharge scripts — and the readings will stabilise. After the third cycle, the gauge percentage should track actual capacity within a few percent.
The Asus system info panel shows the wrong Wh rating for this replacement battery — is it pulling incorrect specs?
The Wh value displayed in Windows or the BIOS comes from the battery's EEPROM, which stores the rated specification written at the factory. If the displayed figure differs slightly from the 51.84Wh on this listing, it means the EEPROM holds a rounded or variant-rated value — the actual cell chemistry and capacity are unchanged. This is a read difference between stored EEPROM data and the measured cell spec, not a sign of a wrong or underspec battery. Verify the actual part number matches A32N1331 or one of the listed OEM codes, and treat the EEPROM-reported Wh as informational only.
