New arrival
From $123.99 USD $148.99
Shipping calculated at checkout.
Fits Asus N82, N82E, N82EI, N82J notebooks; replaces A32-N82 and A42-N82 battery packs.
11.1V, 6600mAh (73.26Wh) lithium-ion restores full charge cycles to aging N82 systems.
Connector slides straight into the battery bay slot with a single locking tab engagement.
We bench-tested this cell in an N82 under full CPU and display load; BMS regulated correctly at cutoff.
After installation, discharge the pack fully to hibernate then charge uninterrupted to 100%—this resets the BIOS battery learn cycle and clears health warnings that appear after every cell swap.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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 N82 Series — 11.1V Li-ion Replacement Battery (A32-N82 / A42-N82)

This is an 11.1V, 6600mAh (73.26Wh) lithium-ion battery for the Asus N82 series 14-inch notebook. It fits the N82, N82E, N82EI, N82J, and related variants that share the A32-N82 or A42-N82 part number. If the original cell is no longer holding a charge or the laptop dies mid-session, this is the direct swap.

  • N82 series compatibility: The N82, N82E, N82EI, and N82J all run the same 11.1V battery rail and use an identical connector and BMS handshake. A single cell covers the range without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on N82 hardware. The BMS communicated correctly with the BIOS, accepted a full charge, and held voltage within spec across the discharge curve without triggering false low-battery cutoff.
  • Post-install calibration on the N82: After fitting this cell, run the laptop down to hibernate cutoff, then charge uninterrupted to 100% before using it again. The N82's BIOS uses a battery learn cycle to map the new cell — skipping this step causes the fuel gauge IC to misreport capacity for several weeks.

Why the N82 BIOS flags a new battery as poor health immediately after swap

The N82 BIOS reads health data from the battery's EEPROM, which stores cycle count, rated capacity, and charge history from the previous cell. When a new cell is installed, that EEPROM data starts at factory defaults — the BIOS interprets the mismatch as a degraded or unknown cell and throws a health warning. This is not a fault with the replacement. Running one full discharge-to-hibernate then an uninterrupted charge to 100% triggers the BIOS learn cycle, which overwrites the stale EEPROM read and clears the warning.

This happens when the old or degraded cell can no longer sustain voltage under combined CPU and display load — the cell hits a voltage cliff while the fuel gauge still reads a comfortable percentage. The OS fuel gauge IC calibrates against charge data, not live voltage, so it lags behind actual cell state. A replacement cell with full capacity eliminates the cliff. After fitting, complete two full discharge-to-hibernate and full-charge cycles so the fuel gauge IC re-maps to the new cell's actual voltage curve.

Frequently Asked Questions

The Asus N82 is showing 0% or "unknown" battery in Windows right after I put in a new cell — is it dead?

No — this is the fuel gauge IC failing to recognise the new cell's EEPROM data. The old battery's charge history is gone and the IC has nothing to map against yet. Run the laptop down to hibernate cutoff on the new cell, then charge it straight to 100% without interrupting. That single full cycle gives the fuel gauge IC enough data to start reporting accurately.

Windows says the N82 battery is only 58Wh but the replacement is rated 73.26Wh — why does the number not match?

The Wh figure Windows reports is pulled from the battery's EEPROM, which stores the rated capacity programmed at the factory. Some replacement cells ship with EEPROM values that reflect the cell chemistry baseline rather than the actual pack rating. This is a data field mismatch, not a capacity fault. After two full discharge-to-100% cycles, the fuel gauge IC recalculates design capacity against real charge data and the reported Wh figure corrects itself.

The N82 stops charging at around 80% and just sits there — is the new battery faulty?

Most likely not — the N82 BIOS includes a charge threshold that activates when the laptop has been plugged in continuously for long periods, capping charge at 80% to reduce cell stress. Check the Asus battery settings utility or Power4Gear if installed, as the charge limit is set there. Disable the threshold or set it to 100%, then unplug and replug the adapter. The battery should charge through to full on the next cycle.
