Samsung Galaxy S23 5G replacement battery

The KingSener EB-BS912ABY is a new lithium-ion cell designed as a direct replacement for the Samsung Galaxy S23 5G SM-S911B. It restores original runtime for owners whose factory battery has degraded. Buyers needing power for a different phone model cannot use this part.

3900mAh capacity at 3.88V

The single specification that determines compatibility is the 3900mAh capacity paired with a 3.88V nominal voltage. These figures must match the original battery label exactly. A different capacity or voltage indicates the wrong part for this device.

Fits the existing battery compartment

The cell matches the original dimensions so it sits in the standard compartment without modification. No extra adapters or cables are required. The battery arrives ready to install after the old unit is removed. Builders who need a higher capacity than 3900mAh must look elsewhere.

Questions about this item

What does the 3900mAh capacity mean for daily use in a Galaxy S23?

It matches the original battery's rated capacity so the phone should deliver the same screen-on time and standby life you had when the device was new.

How does the 3.88V nominal voltage affect charging and compatibility?

The cell uses the standard lithium-ion voltage the S23's charging circuit expects, so the phone charges to its normal peak and reports capacity correctly.

Will this battery fit the S23 without modification?

Yes, it is built to the same physical dimensions as the original EB-BS912ABY and requires no adhesive changes or frame adjustments.
