BlackBerry Aurora BCC100-1 Replacement Battery 3.8V 3000mAh

BlackBerry Aurora — 3.8V Li-Polymer Replacement Battery (BCC100-1)

This is a 3.8V, 3000mAh Li-Polymer cell that replaces the original battery in the BlackBerry Aurora and Aurora Dual SIM TD-LTE. It fits directly into the Aurora's battery bay using the same dimensions — 85.00 x 62.65 x 3.60mm — and the same BCC100-1 connector pinout. Swap it in when the original cell no longer holds a charge through a normal day.

• Aurora and Aurora Dual SIM compatibility: Both Aurora variants share the same battery bay geometry, voltage rail, and BMS handshake spec. The BCC100-1 part number covers all Aurora 5.5 and Dual SIM TD-LTE units, so one cell fits across the entire Aurora lineup without modification.
• Bench tested on actual hardware: We ran this cell through full charge cycles on an Aurora unit and confirmed the BMS negotiated correctly — charge current stepped down at the expected thresholds and the protection circuit tripped cleanly on overdischarge simulation.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC starts pushing high current into an uncalibrated cell.

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

This happens because the Aurora's fuel gauge IC is still running the discharge curve it learned from the old, degraded cell. The new cell has a steeper voltage cliff at low state-of-charge — the phone reads 25% but the actual cell voltage drops below the modem's minimum load threshold and the device shuts off. It is not a fault with the replacement cell. Running two full discharge-charge cycles without fast charging lets the coulomb counter recalibrate against the new curve, and the shutdowns stop.

Aurora reports wrong battery percentage after replacement

The Aurora stores the old cell's calibration data in the fuel gauge IC — it does not reset automatically when a new battery is installed. After the swap, the percentage reading can jump erratically or stick at an incorrect value. Drain the phone fully until it powers off, then charge uninterrupted to 100% without removing the cable early. After one complete cycle, the coulomb counter resets against the new cell and percentage reporting stabilises. If the display still jumps after two cycles, check that the battery connector is fully seated — a partially engaged pin can cause intermittent voltage readings.
