Samsung Galaxy A3 2017 Replacement Battery EB-BA320ABE 3.85V

Up to 21% off
New arrival
From $24.99 USD $30.99
Shipping calculated at checkout.
Fits Samsung Galaxy A3 2017 (SM-A320, SM-A320FL) and replaces EB-BA320ABE and GH43-04677A.
Delivers 3.85V and 2350mAh capacity — matches original output for full-day typical use without reduced performance.
Connector seats flush into the battery slot with standard Li-Polymer contact alignment and mechanical lock tab.
We cycled the cell through 5 full discharge-charge rounds; the BMS accepted charge current cleanly and reported accurate voltage throughout discharge.
Disable fast charging for one complete discharge-charge cycle on first use — the fuel gauge IC needs to recalibrate against the new cell's discharge curve before sustained high-current charging.

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 A3 2017 — 3.85V Li-Polymer Replacement Battery (EB-BA320ABE)

This is a 3.85V, 2350mAh Li-Polymer cell built to the EB-BA320ABE specification. It fits the Samsung Galaxy A3 2017 and all SM-A320 variants, including the SM-A320FL and the TD-LTE model lines. Voltage and physical dimensions match the OEM cell exactly — 74.30 × 39.40 × 4.90mm.

  • SM-A320 variant compatibility: The SM-A320, SM-A320FL, and TD-LTE variants share the same battery bay geometry, connector pinout, and 3.85V nominal rail. One cell covers all of them without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge on a Galaxy A3 2017 unit. The BMS accepted the cell, charge IC ramped normally, and no fault codes triggered on the protection circuit during CC-CV transition.
  • Fuel gauge recalibration on first use: After installation, disable fast charging and run one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.

Sudden shutdown at 20–30% on the Galaxy A3 2017 after a cell swap

The Galaxy A3 2017's fuel gauge IC retains the discharge curve from the old, degraded cell. When a new cell with a steeper voltage cliff at low state-of-charge is installed, the IC misjudges the remaining capacity. The phone's modem or display pulls current, voltage drops below the protection threshold, and the device cuts out — even though the reported percentage still reads 20–30%. One full discharge to auto-shutdown followed by a complete charge cycle forces the coulomb counter to re-anchor to the new cell's curve.

Device will not power on after the replacement cell sat in storage

Li-Polymer cells self-discharge in storage. If this cell shipped at a low state of charge and sat unused, the cell voltage may have dropped below 2.5V — the threshold at which the BMS trips into deep-discharge lockout to prevent permanent damage. Plugging in a charger may show nothing for several minutes while the charge IC trickle-charges the cell back above the BMS re-enable threshold. Use the OEM Samsung charger or a 5V/1A source and leave it connected for at least 15 minutes before attempting to power on.

Frequently Asked Questions

My Galaxy A3 2017 keeps shutting off at around 25% after I put in the new battery — is the cell faulty?

The cell is almost certainly fine. The fuel gauge IC in the A3 2017 is still calibrated to your old degraded cell's discharge curve, so it misreads the new cell's voltage drop under load as a hard cutoff. Run one full discharge — let the phone die on its own — then charge uninterrupted to 100% without fast charging. That single cycle re-anchors the coulomb counter to the new cell, and the premature shutdowns should stop.

Fast charging stopped working after I replaced the battery on my Galaxy A3 2017 — it only charges slowly now.

On the first cycle after a cell swap, the charge IC can fall back to standard 5V/1A mode because it has not yet confirmed BMS handshake compatibility with the new cell. This is normal behaviour, not a fault. Complete one full standard-rate charge cycle first. On the second charge, fast charging typically re-enables once the IC has logged a successful charge profile against the new cell.

The battery percentage on my Galaxy A3 2017 is jumping around erratically — one minute it reads 60%, then drops to 40% without warning.

Erratic percentage jumps are a fuel gauge IC recalibration symptom, not a sign of a bad cell. The IC is interpolating state-of-charge from a discharge table built around the old cell's internal resistance and capacity, and the new cell's characteristics don't match that table yet. Discharge the phone completely until it powers itself off, then charge straight to 100% at standard rate without interruption. After that cycle, the IC resets its reference points and percentage readings stabilise.
