EB-L1H7LLA Sprint SPH-L300 Replacement Battery 3.8V 2100mAh

Sprint SPH-L300 / Galaxy Victory 4G — 3.8V Li-ion Replacement Battery (EB-L1H7LLA)

This is a 3.8V, 2100mAh Li-ion battery that fits the Sprint SPH-L300 and the Samsung Galaxy Victory 4G and Galaxy Victory 4G LTE. It replaces OEM part numbers EB-L1H7LLA and EB-L1H7LLABXAR. The cell slots into the original battery bay with no modification required.

• SPH-L300 and Galaxy Victory 4G platform compatibility: All three listed models share the same 3.8V battery bay, connector pinout, and BMS handshake protocol, which is why one cell covers the full group without adapter or modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the SPH-L300 platform. The BMS accepted the cell cleanly, charge termination triggered at the correct cutoff voltage, and there were no false low-battery events during discharge.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.

Sudden shutdown at 20–30% on the SPH-L300 after a cell swap

This happens when the fuel gauge IC is still using the discharge curve from the old, degraded cell. The new cell has a steeper voltage cliff under modem and screen load than the worn cell did, so the phone hits a voltage floor the OS didn't expect at that reported percentage. The system cuts power to protect the SoC before the OS can respond. One full discharge-charge cycle at standard rate lets the coulomb counter re-anchor to the new cell's actual curve, and the shutdowns stop.

Phone warm near the battery compartment during the first charge

A new cell arrives with higher internal impedance than a cycled cell. The charge IC pushes current into that resistance, and some of that energy converts to heat rather than stored charge — this is normal physics, not a fault. Warmth concentrated near the battery bay during the first one or two charges is expected and tapers off as the cell's impedance drops with cycling. If the phone is hot to the touch or charge stops early, remove the phone from the charger and let it cool to room temperature before resuming — then verify the charger output is within the 5V/1A standard specification.
