OUWEE AP18C8K Laptop Battery for Acer Aspire & Swift 3

The OUWEE AP18C8K is a direct-fit 4-cell lithium-ion replacement battery engineered to restore full portable runtime for compatible Acer Aspire, Chromebook 314, and Swift 3 laptop models.

If your laptop’s runtime has dropped or the original battery reports wear, this OUWEE battery delivers a like-for-like electrical match: 11.25V, 50.29Wh (4471mAh), and the AP18C8K / 3INP5/82/70 part identifiers. It’s designed as a replacement pack for a range of Acer notebooks including Aspire 5 A514-52, Chromebook 314 C933, and several Swift 3 SF314 series machines. Before ordering, check the connector and physical layout against your existing pack — manufacturing variations can affect cable length and plug orientation.

How do I confirm this battery fits my laptop?

Check your laptop’s model number and the original battery part printed on the pack. Match the listed replacement part (AP18C8K or 3INP5/82/70), voltage (11.25V) and physical connector shape before purchase.

• Compare the part number on your old battery to AP18C8K / 3INP5/82/70.
• Verify voltage: 11.25V is required for compatibility.
• Physically inspect connector type, cable length and pack dimensions.

What performance should I expect from this 50.29Wh battery?

This pack restores the original battery capacity rating (50.29Wh / 4471mAh) so runtime returns close to factory levels, depending on workload and power settings. It uses Li-ion cells and is intended as a direct replacement, not an upgrade to higher capacity.

• Rated 50.29Wh (4471mAh) for typical factory-equivalent run times.
• 11.25V nominal output to match original system specifications.
• Li-ion chemistry for standard charge/discharge characteristics.

Are there installation tips and initial setup steps?

Installation is straightforward but requires care: power down, remove the back cover, unplug the old pack and reconnect the new one securely. If the system does not immediately recognize the new battery, a few simple cycles will help the battery management system calibrate.

• Power off and disconnect AC before replacing the battery.
• Ensure connector is fully seated; reseat if the battery isn't detected.
• If not recognized, discharge to ~5% and complete 3–4 charge/discharge cycles to stabilize capacity reporting.

What compatibility caveats should I watch for?

Different factories sometimes produce slightly different battery assemblies, so cable length, connector orientation or mounting tabs can vary. Always compare the physical design in the product images and the connector type with your original battery before purchase.

• Check pictures and your laptop’s battery label for matching dimensions.
• Confirm the connector pin layout matches your laptop’s socket.
• Contact the seller for clarification if any physical detail differs.

Who is this for: The OUWEE AP18C8K battery is for owners of compatible Acer and Swift series laptops who want a cost-effective, like-for-like replacement to restore original run time. It suits DIY-savvy users comfortable opening their laptop chassis and matching part numbers, and for technicians replacing worn or failed packs with a 11.25V, 50.29Wh (4471mAh) Li-ion module.
