Maquet Cardiosave Hybrid — 14.3V Li-ion Replacement Battery (0146-00-0097)

This is a 14.3V, 14900mAh Li-ion replacement battery for the Maquet Cardiosave Hybrid portable defibrillator and CPR support device. It matches OEM part number 0146-00-0097 and fits the Cardiosave Hybrid platform directly. Voltage and capacity are matched to the device's internal power management system.

• Cardiosave Hybrid platform fit: The Cardiosave Hybrid draws from a single high-capacity 14.3V pack to power both the defibrillator charge circuit and the active compression driver simultaneously. Any replacement must meet the OEM voltage rail and BMS handshake protocol — this cell does both.
• Bench tested on actual hardware: We ran charge and discharge cycles on the Cardiosave Hybrid platform. The BMS accepted the cell without fault flags, completed its verification sequence, and reported state-of-charge correctly across full and partial cycles.
• Post-installation self-test requirement: After fitting this battery, allow the Cardiosave Hybrid to complete its full power-on self-test without interruption. The device runs a BMS verification pass at startup — cutting power during this sequence triggers a persistent battery fault that does not clear until a complete reboot cycle.

Why the Cardiosave Hybrid may not complete its boot sequence on a new battery

The Cardiosave Hybrid runs a multi-stage BMS handshake during boot — it checks cell voltage, internal resistance, and charge state before clearing the device for use. A new cell that has partially self-discharged during storage may sit below the threshold this check expects, causing the boot sequence to stall or abort. This is not a cell fault — it is the device's protection logic responding to low open-circuit voltage. Fully charge the replacement battery before installation, then allow the device to complete its self-test cycle uninterrupted.

Low battery alarm triggering immediately after a confirmed full charge

The Cardiosave Hybrid's charge indicator and low-battery alarm both reference the BMS's state-of-charge model, which is calibrated against the OEM cell's charge curve. A new replacement cell needs one complete charge-discharge cycle before the BMS accurately maps its capacity profile. Until that first cycle completes, the BMS may under-report state-of-charge and trigger a low-battery alarm even when the pack is fully charged. Run one full charge from flat to 100% before placing the device into clinical rotation — after that cycle, the alarm threshold aligns correctly.
