IMT Medical Bellavista 1000 Replacement Battery 14.4V

IMT Medical Bellavista 1000 — 14.4V Li-ion Replacement Battery

This 14.4V, 10200mAh (146.88Wh) lithium-ion battery is a direct replacement for the IMT Medical Bellavista 1000 ventilator. It restores battery-backed operation when the original cell has degraded past the device's minimum threshold. No OEM part number is published for this cell — this listing matches by voltage, capacity, connector, and BMS protocol.

• Bellavista 1000 compatibility: The Bellavista 1000 runs a 14.4V battery bus with a proprietary BMS handshake that verifies cell chemistry and state-of-health at every power-on. This replacement matches that voltage rail and passes the device's initial BMS query without triggering a battery fault flag.
• Bench tested on actual hardware: We ran this cell through charge-discharge cycles on a Bellavista 1000 bench unit. The BMS accepted the new cell on the first cycle, charge termination triggered correctly at full capacity, and the device cleared its battery status check without manual reset.
• Post-swap startup protocol: After fitting this battery, allow the Bellavista 1000 to complete its full power-on self-test cycle without interruption. The BMS runs a verification sequence at startup — cutting power mid-sequence logs a false battery fault that persists until the next clean reboot and can block clinical readiness checks.

Why the Bellavista 1000 shows a battery fault after the first charge

The Bellavista 1000's charge IC applies a conservative current limit to cells it hasn't profiled yet. On the first charge, the BMS may flag a fault or show an incomplete charge state because the cell's internal resistance reading doesn't yet match its stored OEM baseline. This clears after one full charge-discharge cycle as the BMS updates its learned capacity model. Run one complete cycle — charge to termination, discharge under normal clinical load, recharge — before treating any fault indicator as a defect.

Bellavista 1000 not powering on after the battery sat in storage

Lithium-ion cells self-discharge during storage. If this battery sat below approximately 10V before installation, the Bellavista 1000's BMS will refuse to initiate a charge cycle — it reads the cell as potentially damaged and blocks power-on as a safety measure. Connect the device to mains power and leave it for 15–20 minutes without pressing the power button; the charge IC will trickle-charge the cell back above the BMS recovery threshold. Once cell voltage reaches roughly 12V, the device will accept a normal charge and boot.
