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.

FIC A3 / A320 Series — 14.8V Li-ion Replacement Battery
This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for FIC A3 series notebook computers. It fits the A3, A320, A320 Plus, A360, and over a dozen additional A-series variants. When the original cell degrades and the laptop no longer holds a charge away from the wall, this battery restores full mobile operation.
- A3 and A320 series compatibility: These models share a common 14.8V four-cell battery bay, the same connector pinout, and a compatible BMS communication protocol — which is why one replacement cell covers the full A-series range.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and thermal cycling on A-series hardware. The BMS accepted the cell without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
- First-cycle recalibration on the A3: After installing, run one full discharge 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.
BIOS reporting poor battery health after fitting the new cell
The A-series BIOS reads battery health from EEPROM data written by the original cell. When a new cell arrives, its EEPROM values don't match what the BIOS learned from the old one, so the firmware flags it as degraded. This is a calibration mismatch, not a fault with the replacement. One full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle and rewrites the health status against the new cell's actual capacity.
Laptop cutting off at 20–30% charge shown on screen
This happens when the fuel gauge IC hasn't yet calibrated its discharge curve against the new cell chemistry. The displayed percentage is still tracking the old cell's voltage profile, so the reading diverges from actual state of charge under CPU and display load. When real cell voltage drops to the BMS cutoff threshold, the laptop shuts down even though the gauge still shows capacity remaining. Run two to three full discharge-and-recharge cycles and the fuel gauge IC will recalibrate its curve to the new cell — the cutoff point will align with 0% as expected.

Frequently Asked Questions
Why does my FIC A3 show 0% or "unknown battery" in Windows right after fitting the new cell?
The Windows fuel gauge IC pulls state-of-charge data from EEPROM stored on the old cell. A freshly installed cell presents different data, so the OS can't map a percentage and reports 0% or unknown. This isn't a faulty cell — it's a calibration gap. Run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%, and Windows will re-anchor the fuel gauge to the new cell's actual capacity curve.
The system info panel shows the wrong Wh rating after I swapped the battery — is the cell mislabelled?
The Wh figure shown in system info is pulled from the EEPROM of the installed cell, which stores the rated capacity value written at manufacture. If it differs from the 65.12Wh spec, the BIOS learn cycle hasn't yet written updated data against actual measured capacity. After one full calibration cycle — full discharge to hibernate, then a complete uninterrupted charge — the system should reflect the correct Wh value. If it still reads incorrectly, check the BIOS battery settings menu for a stored "last known" value that may need clearing.
My A320 stops charging at around 80% and never reaches 100% — is this a cell defect?
On A-series notebooks, some BIOS versions include a charge limit setting that caps charging at 80% to reduce cell stress during long periods on AC power. This is a firmware control, not a fault with the replacement cell. Open the BIOS setup menu (typically F2 at POST), navigate to the power or battery section, and check whether a charge threshold or battery health mode is enabled — disabling it will allow the cell to charge to 100%.
