SCP-60LBPS Kyocera Brigadier Replacement Battery 3.8V 3100mAh

Kyocera Brigadier / DuraForce Series — 3.8V Li-ion Replacement Battery (SCP-60LBPS)

This 3.8V, 3100mAh Li-ion cell replaces the original battery in the Kyocera Brigadier (E6782) and DuraForce (E6762). It matches OEM part numbers SCP-60LBPS and 5AAXBT076GEA. If your Brigadier or DuraForce is shutting down unexpectedly or no longer holding a charge, this cell fits the original connector and BMS footprint.

• Brigadier and DuraForce shared platform: Both the E6782 and E6762 run the same 3.8V nominal voltage rail and use an identical battery bay geometry with the same connector pinout. One cell fits both — no adapter needed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Brigadier platform. The BMS handshake completed correctly, charge current ramp was normal, and the protection circuit tripped as expected at the low-voltage threshold — no false cutoffs on a fresh cell.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard current. The Brigadier's fuel gauge IC is calibrated to the old cell's discharge curve — without a full recalibration cycle, the coulomb counter will report inaccurate percentages and may trigger early shutdowns.

Sudden shutdown at 20–30% on a replacement cell in the Brigadier

The Brigadier's modem and display draw sharp current spikes under load. A new cell with a slightly different internal resistance profile can cause the voltage to sag below the BMS cutoff threshold even when the reported state of charge looks healthy. The fuel gauge IC hasn't yet mapped the new cell's discharge curve, so it reads 25% while the actual terminal voltage under load drops below 3.4V and the protection circuit shuts the phone down. Fix this with one full uninterrupted discharge to 0% followed by a full charge — the coulomb counter resets its reference baseline against the actual cell behaviour.

Fast charge not accepted by the phone on the first cycle after replacement

After swapping a cell, the charge IC in the Brigadier may fall back to standard 1A charging instead of accepting the higher-current protocol. This happens because the BMS on a new cell starts in a conservative state — it limits charge acceptance until it has completed one full cycle and confirmed cell impedance is within range. Force one complete charge at standard current without interrupting it. On the second cycle, the BMS opens the higher-current path and fast charging resumes at the normal rate — expect the charge IC to accept full current once terminal voltage reaches 4.1V on that second cycle.
