Fits Samsung Galaxy J1 Ace 3G Duos and SM-J110 variants, replaces OEM battery EB-BJ110ABE.
3.8V lithium-ion cell rated 1800mAh delivers stable voltage under modem and display load on this entry-level dual-SIM phone.
Connector slides straight into the battery slot with no locking tab — orientation marked on the pack itself.
We bench-tested against a degraded OEM pack; the BMS accepted full charge on first cycle with no early cutoff.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the fuel gauge IC recalibrates to the new 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 J1 Ace SM-J110 Series — 3.8V Li-ion Replacement Battery (EB-BJ110ABE)

This is a 3.8V, 1800mAh Li-ion replacement battery for the Samsung Galaxy J1 Ace 3G Duos and related SM-J110 variants. It fits the dual-SIM slot configuration without any modification to the battery bay. Capacity is rated at 6.84Wh, matching the original cell specification.

  • SM-J110 series compatibility: The Galaxy J1 Ace, J1 Ace Dual SIM 3G, and J1 Ace 3G Duos all share the same 3.8V battery rail, physical footprint, and connector pinout — which is why a single cell covers all variants in the SM-J110 lineup without BMS handshake conflicts.
  • Bench tested on actual hardware: We cycled this battery on an SM-J110 unit and monitored BMS cutoff thresholds across three full charge-discharge passes. The protection circuit tripped correctly at low-voltage cutoff and the charge IC accepted the cell without error flags on the second cycle.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. The fuel gauge IC in the SM-J110 calibrates its coulomb counter against the actual discharge curve — skipping this step on a fresh cell produces inaccurate percentage readings for the first several cycles.

Why the Galaxy J1 Ace shuts down suddenly at 20–30% after a cell swap

The SM-J110's fuel gauge IC still holds the discharge curve from the old, degraded cell after a swap. When the new cell hits a voltage point the IC incorrectly maps to near-empty, it signals a low-voltage shutdown even though usable charge remains. This is a calibration mismatch, not a fault with the replacement cell. Run two or three full discharge-charge cycles and the IC rewrites its reference curve to match the new cell's actual voltage profile.

Phone reports wrong battery percentage after installing the new cell

The Galaxy J1 Ace uses a coulomb counter that accumulates charge and discharge data over time to estimate state of charge. After a cell replacement, the counter has no valid baseline for the new cell's capacity, so percentage readouts jump or stall at fixed points — commonly 50% or 100%. Allow the battery to drain fully until the phone shuts off, then charge uninterrupted to 100% before first use. After two cycles, the coulomb counter stabilises and percentage reporting becomes accurate.

Frequently Asked Questions

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

It's likely a BMS lockout, not a dead cell. If the cell self-discharged below approximately 2.5V during storage, the BMS trips an over-discharge protection latch and the phone draws no current from it. 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 will trickle current into the cell at a safe rate until voltage recovers enough for the BMS to release the latch, then the phone will charge normally.

The phone feels warm near the battery compartment for the first hour of charging — is something wrong with the new cell?

This is normal behaviour on the first charge cycle of a new high-impedance cell. A fresh lithium-ion cell has slightly higher internal resistance than a broken-in one, so the charge IC dissipates more heat as it pushes current through that resistance. Warmth — not heat — near the battery bay for the first one or two charges is expected and drops off as the cell's internal resistance settles after cycling. If the phone becomes hot to the touch or the back warps, remove it from charge immediately and check that the battery is seated flat with no gap at the connector.

Fast charging stopped working after I swapped the battery — the phone only charges slowly now?

On the first cycle after installation, some charge controllers on the SM-J110 do not immediately negotiate the proprietary fast-charge protocol with a new BMS. The controller defaults to standard 5V/1A input as a safe fallback. Complete one full standard-rate charge cycle to 100%, then disconnect and reconnect the charger — the fast-charge handshake typically re-establishes on the second connection once the BMS has completed its initial charge pass. Use the original Samsung wall adapter, as third-party chargers may not send the correct voltage step-up signal at all.
