Bellavista 1000 Medical Device Replacement Battery 14.4V 10200mAh

Bellavista 1000 Respirator — 14.4V Li-ion Replacement Battery (030.811.020)

This 14.4V 10200mAh lithium-ion battery fits the Bellavista 1000 respirator, a portable medical ventilator used in clinical and home healthcare settings. It replaces OEM part numbers 030.811.020, 300.784.000, 110807-O, and H2B360. Voltage and capacity match the original specification exactly.

• Bellavista 1000 platform fit: The 1000 series respirator uses a 14.4V nominal rail with a BMS handshake that validates cell chemistry and capacity before the device clears for operation. This battery matches the connector pinout and communicates correctly with the device's onboard charge controller.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the Bellavista 1000 platform and confirmed BMS handshake completion, accurate state-of-charge reporting, and clean cutoff behaviour at low-voltage threshold. No fault codes were triggered after the first conditioning cycle.
• First-use self-test cycle: After installing this battery, allow the Bellavista 1000 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence registers a false battery fault that persists until the next complete reboot.

Why the Bellavista 1000 flags a battery fault on a fully charged new cell

The Bellavista 1000 BMS compares incoming cell capacity and internal resistance against thresholds calibrated to a conditioned OEM battery. A brand-new cell has slightly elevated internal resistance out of the box — enough to trigger a soft fault on first use. This clears after one complete charge-discharge cycle, which allows the BMS to update its learned baseline. Do not attempt clinical use until that conditioning cycle is complete.

Charge indicator not reaching 100% on the first charge

On the first charge, the Bellavista 1000 charge IC applies a conservative current limit to an unrecognised cell, which causes the charge cycle to terminate early and display a sub-100% state of charge. This is not a fault — it is a protective behaviour built into the charge controller. Run a full discharge followed by a full charge to allow the charge IC to recalibrate its end-of-charge voltage detection. After that cycle, the indicator should reach 100% consistently.
