Cardiette Cardioline AR1200 Replacement Battery 12V 2000mAh

Cardiette Cardioline ECG Recorder AR1200 Series — 12V Ni-MH Replacement Battery (6113)

This is a 12V 2000mAh Ni-MH replacement battery for the Cardioline ECG Recorder AR1200, AR1200ADV, and AR1200 View FC1400. It replaces OEM part numbers 6113, 120176, 110176, CSA14060, and 88888089. The battery powers the recorder during patient examinations when mains power is unavailable or impractical.

• AR1200 series compatibility: The AR1200, AR1200ADV, and AR1200 View FC1400 share the same 12V battery rail, connector pinout, and BMS handshake protocol, which is why all three models accept the same cell pack. Swapping between these variants requires no adapter or firmware change.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on AR1200-series hardware and confirmed the BMS accepted the cell without fault flags. The protection circuit responded correctly to end-of-discharge cutoff, and charge termination triggered at the expected delta-V threshold for Ni-MH chemistry.
• Post-swap startup protocol: After installing this battery, let the AR1200 complete its full power-on self-test without interrupting the sequence. The device runs BMS verification at startup — cutting power mid-sequence causes a false battery fault that persists until the next clean reboot. Do not press any keys or connect a patient lead until the self-test finishes.

AR1200 not completing boot sequence on a new battery

The AR1200 runs a BMS learn cycle during its first few charge-discharge passes on a new cell. Until that cycle completes, the device may stall partway through boot or display a battery error even when the pack is fully charged. This happens because the charge IC applies conservative current limits on an uncharacterised cell, and the BMS interprets the lower-than-expected charge acceptance as a fault. Run one full charge-discharge cycle before treating the device as ready for clinical use. After that cycle, boot behaviour returns to normal.

Charge indicator not reaching 100% on first charge

On a fresh Ni-MH cell, the AR1200 charge IC applies a conservative current ceiling until the cell's internal resistance profile is established. This means the charge indicator may plateau below 100% on the first charge — the cell is not defective. The delta-V termination threshold that signals full charge is harder to detect on a new, unformed cell, so the controller cuts off early. Allow the battery to go through one complete charge-discharge cycle and the charge indicator will reach full on the second pass.
