Replacement battery for Acer Aspire 5 and Swift 3

This new lithium-ion battery delivers 11.55 volts and 53 watt-hours of capacity. It fits a wide range of Aspire 5, Aspire 7, Swift 3, Vero and TravelMate Spin B3 models. The black pack replaces part numbers KT.0030B.002 and 31CP5/82/70. It is built for owners who need a direct swap for a worn original cell.

Upgrading from a depleted factory pack

The unit replaces the original battery when runtime has dropped or the laptop no longer holds a charge. It restores the 53Wh design capacity without requiring a higher-wattage adapter. The change is worth it when the old cell shows rapid drain, sudden shutdowns or a swollen case. It does not add capacity beyond the factory specification.

Steady output during extended sessions

The lithium-ion chemistry maintains a stable 11.55V supply throughout the discharge cycle. This prevents voltage sag that can throttle the processor during long compiles or video playback. The 53Wh rating supports multi-hour workloads away from mains power. It is not intended for users who need hot-swap capability or a secondary pack for continuous operation.

Questions about this item

Does the AP20CBL battery match the KT.0030B.002 part number used in my Acer Aspire 5 A515-45?

Yes, the battery replaces part numbers KT.0030B.002, 31CP5/82/70 and AP20CBL, which are listed for the Aspire 5 A515-45 series.

What screw sizes or tools are needed to fit the 11.55V pack into a Swift 3 SF314-43?

The pack uses the original mounting points; a small Phillips screwdriver for the bottom-case screws and a plastic pry tool for the clips are all that is required.

When should I expect to replace the 53Wh lithium-ion unit in my TravelMate Spin B3?

Replace it when run time falls well below your needs or the battery swells; the supplier provides a 12-month warranty period.
