About this replacement
Kyocera Cadence LTE / S2720 — 3.8V Li-ion Replacement Battery (SCP-70LBPS)
This is a 3.8V, 1200mAh Li-ion cell that replaces the original SCP-70LBPS battery in the Kyocera Cadence LTE and S2720 / S2720PP smartphones. It matches the original's dimensions at 57.24 × 36.00 × 5.50mm and drops into the same battery bay without modification. Voltage and capacity are spec-matched to work with the phone's existing charge IC and fuel gauge.
- Cadence LTE, S2720, and S2720PP compatibility: All three models share the same battery bay geometry, connector orientation, and BMS handshake protocol — the SCP-70LBPS is the factory-specified cell across this entire lineup, so one part covers all variants.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the S2720 platform, confirmed the BMS accepted the cell without error flags, and verified the charge IC reached a full 4.2V terminal voltage before cutoff.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging and let the phone complete one full discharge-to-charge cycle at standard current. This gives the fuel gauge IC time to map the new cell's discharge curve before any high-current session pushes current into an uncalibrated state.
Sudden shutdown at 20–30% on the Cadence LTE after a cell swap
The Cadence LTE's fuel gauge IC retains the discharge curve data from the old, degraded cell. When a new cell is installed, the IC's voltage-to-percentage mapping is still calibrated to the old cell's internal resistance profile. At high-load moments — active LTE radio, screen-on — the new cell can sag in voltage faster than the IC expects, triggering a low-voltage shutdown even though the reported percentage reads 20–30%. One full uninterrupted discharge cycle below 10% followed by a complete charge resets the coulomb counter and eliminates most of these shutdowns.
Phone warm near the battery compartment during the first charge
A new Li-ion cell arrives with slightly higher internal impedance than a broken-in cell, and the charge IC responds by delivering current into a higher-resistance load — which generates more heat than you'd see after a few cycles. This is normal during the first one or two charging sessions and not a sign of a defective cell. If the back of the phone feels hot to the touch rather than warm, disconnect and let it cool to room temperature before resuming. By the third full charge cycle, impedance drops and the warmth should be minimal.
