Fits Galaxy A53 5G 2022 and SM-A536 variants; replaces EB-BA336ABY and EB-BA536ABY battery packs.
3.85V, 4700mAh Li-Polymer cell restores full charge capacity lost to age-related degradation in the original pack.
Connector seats flush into the battery cavity with the locking tab oriented toward the upper edge of the slot.
We bench-tested the BMS handshake on Samsung's fuel gauge IC; the cell accepted charge current without fault codes on first insertion.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the fuel gauge IC recalibrates against this cell's discharge curve.

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 A53 5G 2022 — 3.85V Li-Polymer Replacement Battery (EB-BA336ABY)

This 3.85V, 4700mAh (18.1Wh) Li-Polymer cell replaces the original battery in the Samsung Galaxy A53 5G 2022. It fits SM-A536U, SM-A536U1, SM-A536R4, and 18 additional regional variants. OEM part numbers covered include EB-BA336ABY, EB-BA536ABY, GH82-28027A, and GH82-28146A.

  • A53 5G variant coverage: The SM-A536 series spans multiple carrier and regional builds — US unlocked, US cellular, and global variants — but all share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell fits all listed SKUs without modification.
  • Bench tested on actual hardware: We ran this cell on an SM-A536U board. The BMS accepted the charge handshake within one full cycle, voltage held steady at 3.85V nominal under modem and display load, and no thermal flags triggered during a standard USB-PD charge session.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging pushes into an uncalibrated state — preventing early percentage jumps or false low-battery warnings.

Why the A53 5G reports wrong battery percentage after a cell swap

The Galaxy A53 5G uses a coulomb counter IC that tracks charge and discharge against the original cell's chemical profile. When you install a new cell, the IC is still referencing the old degraded curve, so the percentage reading diverges from actual cell state. This is not a fault with the replacement cell — it is a calibration lag in the fuel gauge IC. One full discharge from 100% to automatic shutdown, followed by an uninterrupted charge to 100%, resets the reference curve and realigns reported percentage with real capacity.

Sudden shutdown at 20–30% on the replacement cell

This happens when the fuel gauge IC has not yet recalibrated and the cell voltage drops below the modem's minimum load voltage before the OS registers a low-battery state. Under 5G radio or heavy display load, current draw spikes and causes a voltage sag the uncalibrated gauge did not predict. The BMS trips the cell offline to protect it, and the phone shuts down — even though the percentage shown was well above zero. Run one full uninterrupted discharge-charge cycle with 5G enabled; once the coulomb counter recalibrates, the shutdown threshold will realign to the actual cell voltage floor near 3.4V.

Frequently Asked Questions

The A53 5G won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

A Li-Polymer cell stored uncharged for several months can drop below 2.5V per cell, triggering a BMS lockout that prevents normal power-on. Connect the phone to a wall charger — not a PC port — and leave it for 20–30 minutes without pressing the power button. The charge IC needs enough current to pull the cell above the BMS re-enable threshold, typically around 3.0V, before the phone will respond. If the charging LED or screen does not respond after 45 minutes on a wall adapter, try a different cable and adapter before drawing any other conclusion.

Fast charging stopped working after I installed the replacement cell — the phone only trickle charges now.

On the first charge cycle after a cell swap, the A53 5G's USB-PD negotiation can fall back to standard 5W charging because the charge IC is being conservative with an uncalibrated cell. This is a one-cycle behaviour, not a permanent fault. Complete one full charge to 100% at whatever rate the phone accepts, then disconnect and allow one full discharge before plugging in again. After that recalibration cycle, USB-PD fast charge negotiation should resume at the normal 25W handshake.

The battery percentage jumps around erratically — it reads 60%, drops to 40% in minutes, then jumps back up.

Erratic percentage readings on a new cell are caused by the fuel gauge IC recalibrating against an unfamiliar discharge curve — it has no reliable data points yet, so the coulomb counter interpolates badly between readings. The fix is one complete, uninterrupted discharge from 100% down to automatic shutdown, followed immediately by a full charge to 100% with the screen off and no apps running in the background. That single cycle gives the IC enough real-world data to anchor its curve. After one recalibration cycle, percentage readings should stabilise to within 2–3% of actual cell state.
