Samsung EB575152VU Replacement Battery 3.7V 1250mAh

Verizon EB575152VU — 3.7V Li-ion 1250mAh Replacement Battery

This is a 3.7V Li-ion replacement battery rated at 1250mAh (4.63Wh), sourced to OEM part numbers EB575152VU, EB575152VA, and EB575152LA. It fits Samsung smartphones originally sold through Verizon that use this cell format. Voltage, connector, and BMS handshake match the original specification.

• Multi-part-number coverage: The three OEM part numbers — EB575152VU, EB575152VA, and EB575152LA — reference the same physical cell with identical voltage rails, connector pinout, and BMS communication protocol. All three are interchangeable at the hardware level.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on compatible Samsung hardware. The BMS accepted the charge handshake without fault flags, and the fuel gauge IC tracked cell voltage accurately after one full calibration cycle.
• Fuel gauge recalibration after swap: On first use, disable fast charging and run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC map the new cell's actual discharge curve before high-current charging is applied to an uncalibrated cell.

Sudden shutdown at 20–30% on a replacement cell

A new cell has a slightly different internal resistance profile than the original. Under peak load — modem transmit, screen at full brightness, GPS active simultaneously — the cell voltage can sag below the BMS cutoff threshold even when the fuel gauge still reads 20–30%. The phone interprets this as a hard undervoltage event and shuts down to protect the circuit. One full discharge-charge cycle recalibrates the coulomb counter and reduces the frequency of these early cutoffs. If shutdowns persist past two full cycles, check that the battery contacts are fully seated and free of oxidation.

Phone not powering on after the battery sat in storage

Li-ion cells self-discharge during storage at roughly 1–2% per month. If this battery shipped or sat unused long enough to drop below 2.5V per cell, the BMS enters a lockout state and blocks normal charge input to prevent damage to an over-discharged cell. Connect to a wall charger — not a USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC will trickle current into the cell at a low rate until voltage climbs back above the BMS recovery threshold, typically around 2.9V, at which point normal charging resumes.
