Samsung Galaxy Young 2 SM-G130 Replacement Battery 3.7V 1300mAh EB-BG130ABE

Samsung Galaxy Young 2 SM-G130 Series — 3.7V Li-ion Replacement Battery (EB-BG130ABE)

This is a 3.7V, 1300mAh Li-ion battery for the Samsung Galaxy Young 2 series, covering SM-G130, SM-G130E, SM-G130H, and Galaxy Star 2 Duos variants. It replaces OEM part numbers EB-BG130ABE and EB-BG130BBE. Fit this battery when the original cell no longer holds voltage under screen or call load.

• SM-G130 series compatibility: All SM-G130 variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. Swapping between SM-G130, SM-G130E, and SM-G130H requires no adapter — the connector seats identically and the charge IC on each board communicates with the same BMS signal lines.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on an SM-G130H board. The BMS reported correct state-of-charge, thermal cutoff triggered at expected thresholds, and the charge IC maintained stable current throughout.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one complete discharge-to-charge cycle before heavy use. The fuel gauge IC on the SM-G130 is calibrated to the original cell's discharge curve — letting it map the new cell's curve first prevents erratic percentage readings and premature low-battery shutdowns.

Sudden shutdown at 20–30% on the SM-G130 after a cell swap

This happens because the fuel gauge IC still holds the discharge curve of the old, degraded cell in its coulomb counter memory. When the new cell hits a voltage point the IC associates with imminent cutoff on the old cell, it signals shutdown — even though the new cell has usable capacity remaining. One full discharge cycle from 100% down to auto-off, followed by a full charge with fast charging disabled, forces the IC to relearn the voltage-to-capacity curve. After that cycle, shutdowns at 20–30% stop in most cases.

Phone warm near the battery compartment during the first few charges

A new Li-ion cell has slightly higher internal impedance than a cell that has been through several charge cycles. The SM-G130 charge IC pushes current into that higher-impedance cell, and the extra resistive heating makes the back of the handset noticeably warm. This is normal for the first two to three charges and fades as the cell's impedance drops. If warmth persists beyond three full cycles or the phone becomes hot to touch, check that the battery connector is fully seated and no bent pins are creating a high-resistance contact point.
