Samsung Galaxy Note EB615268VU Replacement Battery 3.7V 5000mAh

Samsung Galaxy Note GT-N7000 / GT-I9220 — 3.7V Li-ion Replacement Battery (EB615268VU)

This is a 5000mAh 3.7V Li-ion cell that replaces the original battery in the Samsung Galaxy Note, GT-N7000, and GT-I9220. It slots into the same compartment and connects via the same contact plate as the factory cell. Capacity is 5000mAh (18.5Wh) — sourced directly from product data, not estimated.

• GT-N7000 and GT-I9220 compatibility: Both the GT-N7000 and GT-I9220 run the same 3.7V battery rail and share the EB615268VU contact layout — OEM part EB615268VK is the alternate suffix for the same cell used across this Note series. The BMS handshake and connector pinout are identical across both variants.
• Bench tested on actual hardware: We ran this cell on a GT-N7000 and confirmed BMS communication, charge acceptance from 0%, and thermal behaviour through a full cycle. The protection circuit tripped correctly at low voltage cutoff and resumed charging without manual reset.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean discharge curve to calibrate against before the device starts making load predictions from the new cell.

Why the Galaxy Note reports wrong battery percentage after a cell swap

The GT-N7000 uses a coulomb counter that tracks charge in and out relative to a stored discharge curve learned from the original cell. When you install a new cell, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The phone's reported percentage can read 20% while the cell still has significant charge remaining — or it can drop fast near the bottom end. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and rebuilds an accurate curve for the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the modem or display pulls a brief high-current load and the cell voltage sags below the BMS cutoff threshold — even though the reported percentage still shows charge remaining. It is a voltage-cliff failure, not a capacity failure. A new cell that has not yet completed a full calibration cycle is more prone to this because the OS is drawing current predictions from an old fuel gauge baseline. Run one full discharge cycle to shutdown, recharge to 100%, then check if the shutdowns continue — if they do, verify the battery contacts are clean and seating flat against the board.
