Samsung SCH-LC11 3.7V Replacement Battery 1500mAh Li-ion

USCellular SCH-LC11 / SCH-I100 Geen — 3.7V Li-ion Replacement Battery

This 3.7V, 1500mAh Li-ion cell replaces the original battery in the Samsung SCH-LC11, SCH-LC11R, and SCH-I100 Geen smartphones sold under the USCellular brand. It matches the original cell's voltage, physical dimensions (64.50 × 44.00 × 5.00mm), and connector layout. Install it when the original no longer holds a charge or shuts down unexpectedly under load.

• SCH-LC11 and SCH-I100 Geen compatibility: Both models share the same battery bay dimensions and 3.7V single-cell architecture. The BMS handshake on each device reads voltage and temperature from the same pin configuration, so one cell covers both variants without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the SCH-LC11 platform. The BMS accepted the cell on first connection, voltage reporting was stable across the discharge curve, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first cycle: After installing this cell, run one full discharge to auto-shutoff before recharging. The phone's coulomb counter is still calibrated to the old cell's discharge curve. Skipping this step causes the percentage readout to jump or drop suddenly until the gauge resets against the new cell.

Sudden shutdown at 20–30% on the SCH-LC11 after a cell swap

The SCH-LC11's power management IC uses a stored discharge curve to predict remaining capacity. When a new cell goes in, that curve no longer matches actual cell behavior. Under modem or screen load, the phone draws a current spike the fuel gauge wasn't expecting, voltage sags below the shutdown threshold, and the device cuts off — even though the reported percentage looks fine. One full discharge-to-cutoff cycle lets the IC relearn the new cell's voltage-to-capacity relationship and stops the premature shutdowns.

Phone not powering on after the replacement cell sat in storage

Li-ion cells self-discharge in storage. If this battery arrived at or below 2.5V per cell, the BMS may have entered lockout mode to prevent damage — and the phone will show no response when you press power. Connect the phone to a wall charger (not a USB port) and leave it for 20–30 minutes without pressing anything. The charge IC will trickle current into the cell to bring it above the BMS re-enable threshold, typically around 2.9V, after which normal charging resumes.
