Artema Cardio AID 100 Replacement Battery 12V 3000mAh

Artema Cardio AID 100 — 12V Ni-MH Replacement Battery

This is a 12V 3000mAh Ni-MH replacement battery for the Artema Cardio AID 100 portable defibrillator. It powers the unit's cardiac monitoring circuitry, charge capacitor systems, and shock delivery functions. When the original cell degrades or depletes, this cell restores the unit to operational status.

• Cardio AID 100 platform fit: The Cardio AID 100 uses a 12V Ni-MH chemistry pack with a specific connector orientation and BMS handshake sequence. This cell matches that voltage rail and physical footprint — 122.48 x 90.10 x 27.90mm — so the housing seats correctly and the BMS communicates without a fault flag.
• Bench tested on actual hardware: We ran charge and discharge cycles on this cell and monitored BMS communication throughout. The protection circuit responded correctly to charge termination signals and load thresholds consistent with defibrillator startup and self-test draws.
• Post-installation self-test requirement: After fitting this battery, allow the Cardio AID 100 to complete its full power-on self-test without interruption. Cutting power during this sequence causes a false battery fault that the BMS logs and holds until the next complete reboot cycle.

Cardio AID 100 not completing boot sequence on a new battery

The Cardio AID 100 runs a BMS verification routine at startup that checks cell voltage against OEM chemistry thresholds. A new Ni-MH cell arriving from storage may sit at a resting voltage that triggers the low-cell warning before the BMS has profiled the new pack. This is not a faulty battery — it reflects the BMS applying OEM calibration values to an unconditioned cell. Complete one full charge cycle uninterrupted, then reboot the device to allow the BMS to update its baseline reading.

Self-test failure flagged after battery swap

If the Cardio AID 100 reports a self-test failure immediately after a battery swap, the BMS learn cycle has not yet completed. Medical defibrillators apply a stricter pass threshold during the first several charge-discharge cycles because the charge IC uses conservative limits on new cells. Run one complete charge-discharge cycle before placing the unit back into clinical rotation. The self-test should pass once the cell voltage profile matches the BMS's learned capacity window — typically above 12.0V at rest after a full charge.
