Fits Acer Aspire One Cloudbook 14 and replaces OEM part numbers AP15H8I and KT.0030G.008.
This 11.4V, 4700mAh lithium-polymer cell restores full charge capacity to ultraportable Cloudbook notebooks without external power.
Connector seats into the internal battery slot with single-latch retention — verify latch engagement before closing the chassis.
We ran this cell through five full charge cycles on a Cloudbook 14 unit; BMS accepted the handshake and delivered clean voltage output under CPU and display load.
After installation, run one complete discharge to hibernate-cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings.

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.

Acer Aspire One Cloudbook 14 — 11.4V Li-Polymer Replacement Battery (AP15H8I)

This is an 11.4V, 4700mAh (53.58Wh) lithium-polymer replacement battery for the Acer Aspire One Cloudbook 14 series, including the AO1-431, AO1-431M, and AO1-431-C139. It replaces OEM part numbers AP15H8I and KT.0030G.008. The battery slides into the original bay with the same connector and BMS handshake as the factory cell.

  • Cloudbook 14 series compatibility: The AO1-431 and AO1-431M share the same 11.4V three-cell Li-Polymer architecture, connector pinout, and BMS communication protocol. One replacement battery covers the full Cloudbook 14 range without adapter modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the AO1-431 platform. The BMS handshake completed correctly, charge termination triggered at 100%, and the protection circuit responded normally to low-voltage cutoff conditions.
  • Post-swap calibration on the Cloudbook 14: After fitting this battery, run one complete discharge until the laptop hibernates on low-battery cutoff, then charge uninterrupted to 100%. This forces the Cloudbook's BIOS battery learn cycle to reset against the new cell's actual capacity and clears the false "poor health" warning that commonly appears after every cell swap.

BIOS reporting poor battery health immediately after fitting a new cell

The Acer Cloudbook 14 BIOS reads health data stored in the battery's EEPROM. When you swap cells, the EEPROM on the new battery has no charge history, so the BIOS interprets this as a degraded or unknown cell. This is a data gap, not a battery fault. Running one complete discharge-to-hibernate followed by a full uninterrupted charge gives the fuel gauge IC enough data to update the EEPROM and report accurate health figures — typically within two to three full cycles.

Laptop shuts down abruptly at 20–30% charge shown on screen

This is a voltage cliff issue. When the fuel gauge IC has not yet calibrated against the new cell's discharge curve, it overestimates remaining capacity at mid-range and then hits the actual low-voltage cutoff threshold suddenly. The BMS cuts power to protect the cells before the OS can gracefully hibernate. To fix this, complete two full discharge-to-cutoff and charge-to-100% cycles so the fuel gauge IC maps the real voltage curve. After calibration, the gauge tracks accurately and the abrupt shutdowns stop.

Frequently Asked Questions

My Acer Cloudbook 14 shows the battery as "unknown" or 0% right after I put in a new cell — is it dead?

No — this is the BIOS reading an empty EEPROM on the new battery, not a fault with the cell itself. The old battery had charge history written to its EEPROM; the replacement starts blank. Run the laptop down until it hibernates on low battery, then charge uninterrupted to 100%. After one or two full cycles, the fuel gauge IC writes fresh data to the EEPROM and the BIOS reports correctly.

Windows is showing 53Wh in Device Manager but a different Wh figure in Acer Care Center — which one is right?

The 53.58Wh figure in the product data is the actual rated capacity of this AP15H8I cell. The discrepancy appears because Acer Care Center reads a Wh value from the battery's EEPROM, which may still reflect the original cell's rated figure until the fuel gauge IC completes a calibration cycle. Device Manager pulls its figure from a different register. Complete one full discharge and charge cycle — the EEPROM value will update to reflect the new cell's actual chemistry data.

The replacement battery stopped charging at 80% and won't go higher — did I get a faulty cell?

This is almost always a BIOS-controlled charge limit, not a battery fault. Acer's firmware includes a charge threshold setting in some BIOS and Acer Care Center versions that caps charging at 80% to reduce cell stress during long AC-connected use. Check Acer Care Center under the battery settings tab and disable the charge limit, or enter the BIOS and look for a "Battery Health Mode" or similar option and set it to off. Once disabled, charge the battery fully to confirm it reaches 100%.
