Samsung Galaxy S EB575152VU Replacement Battery 3.7V 3000mAh

Samsung GT-i9000 Galaxy S — 3.7V Li-ion Replacement Battery (EB575152VU)

This is a 3.7V, 3000mAh Li-ion replacement battery for the Samsung GT-i9000 (Galaxy S) and closely related variants including the GT-i9008, SGH-T959W, and Galaxy S series handsets. It replaces OEM part numbers EB575152VU and EB575152VA with matching contact placement and BMS communication. Capacity is rated at 11.1Wh — identical to the original cell specification.

• GT-i9000 / Galaxy S family fitment: These models share the same battery bay dimensions, three-contact connector layout, and BMS handshake protocol. Swapping between variants in this cluster works because the charging IC and fuel gauge IC reference the same cell chemistry and voltage thresholds across the entire Galaxy S first-generation platform.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a GT-i9000 unit. The BMS accepted the charge handshake cleanly, and thermal output during constant-current phase stayed within normal range for a fresh Li-ion cell at this capacity.
• Fuel gauge recalibration on first install: After fitting this battery, run one complete discharge to automatic shutdown, then charge uninterrupted to 100% before normal use. The GT-i9000's fuel gauge IC reads coulomb-counting data calibrated to the old, degraded cell — it needs one full cycle against the new discharge curve to report accurately.

Sudden shutdown at 20–30% on the GT-i9000 after a cell swap

The GT-i9000 uses a coulomb counter that was calibrated to the original, degraded cell's voltage curve. A new cell holds voltage flatter across most of the discharge range, then drops steeply. When the phone's modem or display pulls high current near that cliff, voltage sags below the BMS protection threshold — around 3.0V — and the phone cuts out even though the percentage gauge still reads 20–30%. One full discharge-to-shutdown cycle followed by a complete charge corrects the fuel gauge mapping. After that cycle, shutdowns at falsely high percentages should stop.

GT-i9000 not powering on after the replacement battery sat in storage

Li-ion cells self-discharge during storage. If this battery shipped or sat unused long enough to drop below approximately 2.5V, the BMS locks out to prevent cell damage — and the phone will show nothing when you press power. Connect the phone to a wall charger, not a PC USB port, and leave it for 15–20 minutes without pressing anything. The charge IC on the GT-i9000 trickle-charges a locked-out cell at low current until the BMS releases at around 2.9V, after which normal charging resumes and the phone will power on.
