ABCI760FDZ Verizon SCH-I760 Replacement Battery 3.7V 2500mAh

Verizon SCH-I760 — 3.7V Li-ion Replacement Battery (ABCI760FDZ)

This 3.7V 2500mAh Li-ion cell replaces the original ABCI760FDZ battery in the Samsung SCH-I760 on Verizon. The SCH-I760 is a touchscreen Android smartphone released around 2010. Swap this in when the original cell no longer holds a usable charge between top-ups.

• SCH-I760 fitment: The ABCI760FDZ footprint is specific to the SCH-I760 chassis — the contact spacing, locking tab position, and BMS pin layout match the phone's battery bay directly. No adapter or modification is needed.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the SCH-I760 platform. The BMS handshake completed normally, charge current ramped correctly, and the phone accepted the cell without error flags.
• Fuel gauge recalibration on first use: After installing this cell, disable any fast-charge mode and run one complete discharge-charge cycle before normal use. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve — skipping this step causes the percentage readout to drift noticeably in the first few days.

Sudden shutdown at 20–30% on the SCH-I760 after a cell swap

This is a voltage cliff issue, not a capacity fault. The fuel gauge IC is still reading percentage against the old cell's discharge curve, so the reported percentage no longer lines up with actual cell voltage. Under screen-on or modem load, the new cell's voltage drops faster than the gauge expects and the phone cuts power before the displayed percentage reaches zero. One full discharge-charge cycle forces the coulomb counter to relearn the curve. After that cycle, shutdowns below 30% stop occurring on a healthy cell.

Phone does not power on after the replacement cell sat in storage

Li-ion cells self-discharge during storage. If the cell voltage has dropped below approximately 2.5V per cell, the BMS enters a lockout state and blocks current flow to protect the cell from an uncontrolled charge. The phone shows nothing when you press the power button — not a boot screen, not a charging indicator. Connect the phone to a wall charger and leave it undisturbed for 15–20 minutes. Most BMS circuits will accept a trickle from the charge IC at this point, recover the cell voltage above the lockout threshold, and allow normal charging to resume.
