Samsung EB575152VU Replacement Battery 3.7V 1550mAh Li-ion

Verizon EB575152VU — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1550mAh Li-ion replacement battery for Samsung smartphones that originally shipped with OEM part number EB575152VU. It also cross-references EB575152VA, EB575152LU, and EB575152LA. If your original cell no longer holds a charge or the phone shuts down unexpectedly, this cell replaces the stock unit directly.

• Cross-reference compatibility: The EB575152 series shares a single physical footprint and connector across several Samsung smartphone variants. Verizon distributed the same cell under slightly different suffix codes (VA, LU, LA, VU) — all use the same voltage rail and connector pinout, so one cell covers the full group.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible Samsung hardware. The BMS accepted charge immediately, voltage climbed steadily to 4.2V, and no cutoff events triggered during load testing at normal screen and modem draw.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% on a replacement cell

This happens because the fuel gauge IC in the phone is still referencing the discharge curve of the old, degraded cell. The new cell has a steeper voltage cliff under modem and screen load than the phone expects. When voltage briefly sags under that load, the IC reads it as critically low and triggers a protective shutdown — even though the cell still has capacity. One full discharge-charge cycle on the new cell forces the coulomb counter to remap against the actual discharge curve, which eliminates most false shutdowns.

Phone reports wrong percentage after cell swap

The fuel gauge IC calibrates to the discharge curve of the cell it last tracked. Swapping in a new cell breaks that calibration — the IC continues using stale reference data, so the percentage readout drifts or jumps erratically. Drain the battery until the phone shuts itself off, then charge uninterrupted to 100% without unplugging early. After one complete cycle the coulomb counter resets to the new cell's curve and percentage reporting stabilises.
