Direct replacement for Acer Aspire 5 and Swift 3

This KingSener AP18C8K lithium-ion battery delivers 4200mAh at 11.4V for 48Wh of capacity. It fits Acer Aspire 5 A514-52 and Swift 3 SF314 models listed by the supplier. The pack is black and ships in new condition.

Voltage and connector must match the original part

The replacement operates at 11.4V and uses the form factor tied to part numbers such as 3INP5/82/70, N17W7, N19Q2, N19H4, N19C4 and N20C5. A different voltage or pin layout will prevent the laptop from recognising the pack.

Capacity of 4200mAh or 48Wh decides runtime

This single figure determines how long the machine runs on battery power. If the original unit was rated higher, expect shorter unplugged sessions; if it was lower, expect longer sessions.

Questions about this item

Should I choose the 4200mAh 48Wh version or a different capacity for my Acer Aspire 5 A514-54?

This model is offered only as 4200mAh and 48Wh at 11.4V; select this single capacity that matches the original AP18C8K specification.

What runtime can I expect from the 48Wh rating once the battery is installed in my Swift 3 SF314-58?

The 48Wh capacity at 11.4V restores the factory-rated energy budget; actual runtime depends on your workload, screen brightness and power settings.

Does the 11.4V Li-ion interface limit charging speed or compatibility with Acer Chromebook 314 C933?

The 11.4V Li-ion pack uses the original connector and voltage for all listed models including the Chromebook 314 C933, so charging follows the laptop's built-in controller.
