Direct replacement for Galaxy S20 5G

This KingSener EB-BG980ABY battery is built for the Samsung Galaxy S20 5G SM-G981U. It supplies 4000mAh at 3.86V using Li-ion cells. The unit matches the original dimensions so it fits without modification. It is sold new and targets owners whose factory cell no longer holds a useful charge.

Restores original runtime when the old cell fades

Swap this in when the original battery drains quickly or shuts down prematurely. The 4000mAh capacity matches the design spec, so daily screen-on time returns to factory levels. The jump is worth it once the phone can no longer last a typical workday on a single charge. No capacity inflation is claimed.

Fits the existing chassis and connector

The battery uses the same footprint and connector as the OEM part, requiring no adapter or case alteration. It frees you from carrying a power bank for routine use. Builders who need a higher-capacity cell or a different voltage should look elsewhere, as this unit replicates the stock specification exactly.
