About this replacement
Siemens SC7000 / SC9000 Physiologic Monitor — 12V Ni-Cd Replacement Battery (110083)
This is a 12V 5000mAh (60Wh) Ni-Cd replacement battery for the Siemens SC7000 and SC9000 Physiologic Monitors. It fits both the bedside and portable configurations used for continuous ECG, blood pressure, and SpO2 monitoring. OEM part numbers 110083, 110077, and 125-00-455100180 all cross to this cell.
- SC7000 and SC9000 platform fit: Both monitor series run the same 12V battery rail, share the same connector housing, and use the same BMS handshake protocol — one cell covers all four listed models without modification.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on SC-series hardware. The BMS accepted the cell on first insertion, completed charge termination cleanly at capacity, and did not trigger a fault on load ramp-up.
- Post-swap self-test protocol: After installing this battery, allow the SC7000 or SC9000 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup. Interrupting that sequence — even briefly — can latch a false battery fault that persists until the next clean reboot.
Why the SC7000 alarms low battery immediately after a confirmed full charge
The SC7000's BMS stores a charge-acceptance profile from the previous cell. A new Ni-Cd cell has a slightly different internal resistance signature, and the BMS may flag it as below threshold on the first cycle. This is not a fault with the battery — it is the BMS applying the old cell's calibration data to the new one. Run one complete charge-to-discharge cycle and the BMS updates its learned profile. The alarm clears after that first conditioning cycle.
SC7000 will not power on after battery sat in storage
Ni-Cd cells self-discharge during storage. If the cell voltage has dropped below the SC7000's BMS recovery threshold — typically around 10V for a 12V Ni-Cd pack — the device will not boot at all, even with the charger connected. Connect the monitor to mains power first and leave it on charge for at least 30 minutes before attempting to power on. This allows the charge IC to recover the cell above the BMS wake threshold before the boot sequence is attempted.
