Kyocera E6710 SCP-51LBPS Replacement Battery 3.7V 2050mAh

Kyocera Torque / E6710 Series — 3.7V Li-ion Replacement Battery (SCP-51LBPS)

This is a 3.7V, 2050mAh (7.59Wh) Li-ion cell built to fit the Kyocera E6710, Torque, E6715, and Torque XT. It replaces part number SCP-51LBPS directly. If your original cell is swelling, failing to hold charge, or causing unexpected shutdowns, this swap restores the phone to full function.

• E6710 and Torque XT platform fit: The E6710, Torque, and Torque XT share the same battery bay dimensions and connector pinout. All four models use the SCP-51LBPS footprint, so the same cell covers the full lineup without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Torque platform. The BMS handshake completed cleanly, charge IC accepted the new cell without flagging errors, and voltage held steady across the discharge curve.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before it starts reporting accurate percentages to the OS.

Sudden shutdown at 20–30% on the Kyocera Torque after a cell swap

This is a voltage cliff issue, not a capacity fault. Under modem radio load or screen brightness peaks, the new cell's internal resistance causes a brief voltage dip that the phone's protection circuit reads as a critical low-battery event. The phone shuts off even though the coulomb counter still shows charge remaining. One full slow discharge-charge cycle lets the fuel gauge IC recalibrate its voltage-to-percentage map against the new cell. After that cycle, the shutdown threshold aligns correctly and the cliff disappears.

Phone stays warm near the battery during the first few charges

A fresh cell has higher internal impedance than a broken-in one. During the first two or three charge cycles, the charge IC pushes current into a cell that resists it more than the old degraded cell did, generating more heat at the battery contact area. This is normal and not a fault. Warmth should reduce noticeably by the third full charge cycle. If the phone stays hot or the back feels hot to the touch beyond cycle three, check that the battery connector is seated flat and not partially lifted at one edge.
