Samsung Galaxy Note II EB595675LU Replacement Battery 3.8V 3100mAh

Samsung Galaxy Note II GT-N7100 — 3.8V Li-ion Replacement Battery (EB595675LU)

This is a 3.8V, 3100mAh Li-ion replacement battery for the Samsung Galaxy Note II. It fits the GT-N7100, GT-N7105, and Galaxy Note II LTE 32GB among other Note II variants. Swap it when the original cell no longer holds enough charge to carry the device through a normal day.

• GT-N7100 and GT-N7105 compatibility: Both models use the same 3.8V rail, identical connector footprint, and share the EB595675LU part number — the BMS handshake and charge termination logic are the same across the full Note II family.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a GT-N7100. The BMS accepted charge termination correctly, held cutoff above 3.0V under load, and passed over-temperature protection thresholds without event.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle to the end. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated register.

Why the GT-N7100 reports wrong battery percentage after a cell swap

The Galaxy Note II uses a coulomb counter in the fuel gauge IC to track charge state. When a new cell goes in, the IC still holds calibration data from the old, degraded cell. The percentage shown on screen reflects that stale curve — not the actual state of the new cell. One full discharge to shutdown followed by an uninterrupted charge to 100% resets the coulomb counter to the new cell's actual capacity.

Sudden shutdown at 20–30% on the replacement cell

This happens when the fuel gauge IC has not yet calibrated to the new cell's voltage-versus-capacity curve. The phone reads 25% but the cell's actual open-circuit voltage drops below the modem or display load threshold — triggering an emergency shutdown. It is not a faulty cell. Force a full discharge until the phone powers off on its own, then charge to 100% without interruption. After that cycle, the IC maps the correct low-voltage cliff and shutdowns at false percentages stop.
