AVACOM Li-Polymer Battery for Acer Swift 3 SF314 / Swift 5 SF514 – 15.4V 3545mAh 55Wh, 4-Cell, Black

This AVACOM replacement battery restores full mobility to Acer Swift 3 SF314 and Swift 5 SF514 ultrabooks. Unlike generic packs with uncertain cell quality, it uses a genuine 4-cell lithium-polymer configuration rated at 15.4 V, 3545 mAh and 55 Wh, matching the original energy density for consistent runtime and stable voltage under load. The internal design fits precisely into the slim chassis without bulging, and the black finish keeps the laptop’s appearance unchanged.

Highlights

• Exact electrical match: 15.4 V, 3545 mAh, 55 Wh – same as the OEM battery.
• 4-cell Li-Polymer construction for high energy density and long cycle life.
• Built-in protection against overcharge, over-discharge, over-current, short-circuit and over-temperature.
• CE and RoHS certified, brand new condition, 24-month warranty.
• Replaces Acer part numbers AC16A8L, AP16A8L, AP16A8K.

In daily use

After installation, the battery is recognised by the laptop’s firmware without driver changes. It charges with the original AC adapter and delivers the expected runtime for office work, browsing and video playback. The protection circuit prevents damage from accidental full discharge or power surges, extending the battery’s service life. Because the pack is internal, no tools beyond a small Phillips screwdriver are needed for most Swift models – but professional installation is recommended if you are not familiar with opening the bottom cover.
