Samsung Galaxy Note II EB595675LU Replacement Battery 3.7V 2200mAh

Samsung Galaxy Note II GT-N7100 — 3.7V Li-ion Replacement Battery (EB595675LU)

This is a 3.7V, 2200mAh Li-ion battery for the Samsung Galaxy Note II, covering GT-N7100, GT-N7105, and the Galaxy Note II LTE 32GB among other variants. It replaces OEM part numbers EB595675LU, EB-L1J9LVD, and GH43-03756A. Fit the replacement when the original cell no longer holds a charge, swells, or triggers unexpected shutdowns.

• GT-N7100 and GT-N7105 compatibility: Both the standard Note II and the LTE variant use the same physical footprint, connector tab position, and BMS handshake protocol — one cell covers the full lineup.
• Bench tested on actual hardware: We cycled this cell on a GT-N7100 unit and confirmed the BMS communicates correctly with Samsung's charge IC — charge acceptance, voltage regulation, and temperature reporting all behaved within spec across multiple cycles.
• Fuel gauge recalibration on first use: Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The fuel gauge IC needs one full cycle against the new cell's discharge curve before it can report accurate percentages — skipping this step produces erratic readings for several days.

Sudden shutdown at 20–30% on the Note II after a cell swap

This is a voltage cliff problem, not a capacity problem. Under heavy modem or display load, the cell voltage drops sharply below the threshold Samsung's power IC treats as a safe cutoff — even though the fuel gauge still shows charge remaining. The coulomb counter is still calibrated to the old cell's internal resistance curve, so it misreads remaining energy. One full discharge to automatic shutdown followed by a full charge corrects the counter and pushes the cliff back below the 5% mark.

Phone stays on the Samsung logo and won't boot after the battery sat in storage

Li-ion cells stored partially discharged can drop below 2.5V per cell, which triggers BMS lockout — the protection circuit opens and blocks all current flow to prevent damage. The phone sees no supply voltage and stalls at the boot logo or shows nothing at all. Connect the phone to a wall charger — not a PC USB port — and leave it for 20–30 minutes without pressing any buttons. Most BMS circuits re-initialise once the charger pushes the cell back above 2.8V, after which the phone boots normally.
