Fits Samsung Galaxy S24+ and replaces OEM battery EB-BS926ABY.
Output voltage is 3.88V at 4600mAh capacity—supplies full-day runtime on the S24+ platform.
Connector seats flush into the adhesive slot below the display; orientation is keyed.
We ran a full discharge cycle on bench; the BMS accepted USB-PD without fault codes.
On first charge after installation, disable fast charging for one complete cycle—the fuel gauge IC needs to recalibrate against this cell's discharge curve before high-current charging resumes.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Samsung Galaxy S24+ — 3.88V Li-Polymer Replacement Battery (EB-BS926ABY)

This is a 3.88V, 4600mAh (17.85Wh) Li-Polymer replacement battery for the Samsung Galaxy S24+ (SM-S926 series). It fits all SM-S926 variants and directly replaces OEM part EB-BS926ABY or GH82-33334A. Install it when the original cell has degraded and the phone can no longer hold a charge through a normal day.

  • SM-S926 series compatibility: All SM-S926 variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The fuel gauge IC on every S24+ communicates over a single-wire interface — this cell's embedded BMS speaks that protocol without modification.
  • Bench tested on actual hardware: We cycled this cell on an SM-S926B through charge, full discharge, and a second charge while monitoring BMS cutoff voltages. The protection circuit tripped correctly at the low-voltage threshold and accepted a full USB-PD charge cycle without negotiation errors.
  • First-cycle calibration on the S24+: On first use after installation, disable fast charging for one complete discharge-charge cycle. The S24+ fuel gauge IC holds the old cell's discharge curve in memory. Running one slow cycle lets the coulomb counter recalibrate against the new cell before high-current fast charging pushes current into an uncalibrated state.

Why the S24+ reports wrong battery percentage after a cell swap

Samsung's fuel gauge IC on the S24+ tracks charge state using a coulomb counter anchored to the original cell's discharge curve. When you swap in a new cell, that stored curve no longer matches the new cell's actual voltage-versus-capacity profile. The result is percentage readings that appear stuck, jump suddenly, or hit 100% faster than the cell is actually full. One full discharge down to auto-shutdown followed by a slow charge to 100% forces the IC to rebuild its reference curve against the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the fuel gauge IC hasn't recalibrated and the phone hits an actual cell voltage of around 3.5V while still displaying 25% remaining. Under modem or display load, current draw spikes and the cell voltage drops below the BMS protection floor faster than the OS can register the change. The phone shuts down hard to protect the cell. To clear this, run the phone down to auto-shutdown without fast charging enabled, then charge uninterrupted to 100% — after one full cycle the fuel gauge IC anchors its cutoff estimate to the correct voltage floor.

Frequently Asked Questions

USB-PD fast charging isn't working on my S24+ after putting in the new battery — is something wrong?

This is expected on the first charge cycle after a cell swap. The S24+'s charge IC runs a brief negotiation handshake with the battery BMS before allowing high-current input, and a freshly installed cell sometimes completes that handshake on the second cycle rather than the first. Plug in with fast charging enabled, let it charge fully, then unplug and replug — fast charging should engage normally on the second session. If it still doesn't negotiate, check that the battery connector is fully seated, as a partially engaged pin can break the BMS communication line.

My S24+ won't turn on at all after the replacement battery sat in a drawer for a few months — what happened?

Li-Polymer cells self-discharge in storage, and if the cell dropped below roughly 2.5V per cell, the BMS trips into lockout mode to prevent damage. The phone won't boot because the BMS is blocking output until it sees a trickle charge signal. Connect the phone to a charger and leave it for 20–30 minutes without pressing the power button — the charge IC delivers a low-current precharge to bring the cell above the BMS recovery threshold. Once the cell climbs back above approximately 3.0V, the BMS releases and the phone should power on normally.

The battery percentage on my S24+ keeps jumping around erratically — it went from 60% to 41% in two minutes without heavy use.

The coulomb counter inside the S24+'s fuel gauge IC is still referencing the discharge curve from the old, degraded cell. Because the new cell holds voltage more firmly at lower states of charge, the IC misreads the voltage signal and reports large jumps when it crosses a threshold calibrated for the old cell. Run one full uninterrupted discharge to auto-shutdown, then charge slowly to 100% with fast charging off. After that single cycle the fuel gauge rebuilds its curve and percentage reporting stabilises.
