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 Eee PC 701 Series — 7.4V Li-ion Replacement Battery (A22-700)
This is a 7.4V, 4400mAh (32.56Wh) Li-ion replacement battery for the Asus Eee PC 701, 701C, 800, and 801, plus fifteen additional Eee PC variants. It uses OEM part numbers A22-700, A22-P701, and 90-OA001B1100. The physical dimensions are 140 x 38 x 40mm — measure your original before fitting if you are unsure which bay revision you have.
- Eee PC 700 and 800 series compatibility: These models share the same 7.4V two-cell battery rail, identical connector pinout, and the same BMS handshake protocol — which is why one cell covers the full range from the 701 through to the 801 variants.
- Bench tested on actual hardware: We ran this cell on an Eee PC 701 and confirmed the BMS completed a full charge cycle without false overcurrent trips. Voltage held steady at 8.2V peak under light CPU and display load, with no premature cutoff events recorded.
- Post-install discharge cycle on the Eee PC: After fitting, let the battery discharge fully until the unit hibernates, then charge uninterrupted to 100%. The Eee PC's BIOS runs a battery learn cycle against this event — skipping it leaves the fuel gauge misreading capacity for weeks.
BIOS reporting poor battery health immediately after swap on the Eee PC 701
The Eee PC's BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported values. A fresh cell has different charge cycle counters and capacity figures than the worn-out unit it replaced, so the BIOS flags a mismatch as degraded health. This is a firmware interpretation issue, not a cell fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle data and clears the warning.
Eee PC shutting down at 20–30% charge shown on the gauge
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge is still mapping charge percentage to the old cell's degraded curve, so it calls 20–30% where the new cell's voltage actually drops to cutoff. The fix is two to three full discharge-to-hibernate and charge-to-100% cycles — each one tightens the IC's internal map. After the third cycle, the displayed percentage at shutdown should sit below 5%.

Frequently Asked Questions
The Eee PC shows the battery as "unknown" or 0% right after I installed the new cell — is the battery dead?
The Eee PC's BIOS reads identification data from the cell's EEPROM, and a brand-new cell has no charge history written yet, so the system returns an unknown or zero reading on first boot. This is not a dead cell. Power on the laptop with the charger connected, let it charge uninterrupted to 100%, then discharge fully to hibernate — the BIOS learn cycle will write valid data on that first complete pass and the gauge will report correctly afterward.
The system info panel shows a Wh rating that doesn't match the 32.56Wh on the product listing — which one is right?
The figure shown in the OS or BIOS is pulled from the cell's EEPROM, which stores the manufacturer's rated chemistry value, not the measured capacity of your specific unit. Small differences between the EEPROM figure and the listed 32.56Wh are normal and do not indicate a fault. The 32.56Wh on this listing reflects the actual cell chemistry we sourced and bench-verified. If the discrepancy is large — more than 5Wh — run a full discharge-to-hibernate cycle and recheck; the BIOS recalculates the displayed figure after a completed learn cycle.
The new battery charges fine but the fuel gauge reading jumps around wildly for the first few sessions — is the BMS faulty?
The fuel gauge IC on the Eee PC's charging circuit needs several full cycles to map the new cell's voltage-to-capacity curve accurately. Until it has that data, percentage readings can skip or swing between charges. This is a calibration gap, not a BMS fault. Run three complete discharge-to-hibernate and charge-to-100% cycles without interrupting any of them, and the gauge will stabilise — most users see consistent readings by the end of the third cycle.
