Bellavista 1000 Medical Device Replacement Battery 14.4V 6400mAh

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

This 14.4V 6400mAh Li-ion battery replaces the original pack in the Bellavista 1000 respirator. It fits the Model 1000 platform and carries OEM part references 030.811.020, 300.784.000, 110807-O, and H2B360. Capacity is 92.16Wh — sourced to match the original cell specification exactly.

• Bellavista 1000 platform fit: The 1000 and Respirator variants share the same 14.4V bus, connector pinout, and BMS handshake protocol. This battery communicates with the device charge IC using the same data line as the OEM pack — no firmware mismatch flag.
• Bench tested on actual hardware: We cycled this cell through charge and load on the Bellavista 1000 platform. The BMS completed authentication, the charge IC accepted the pack without fault codes, and the cell held stable voltage under sustained ventilator draw.
• Post-swap self-test protocol: After installation, let the device run its full power-on self-test without interruption. The Bellavista 1000 runs a BMS verification sequence at startup — cutting power mid-sequence stores a false battery fault that persists until the next complete reboot cycle.

Bellavista 1000 not completing boot sequence on a new battery

The Bellavista 1000 runs a BMS authentication check during boot. A new cell that hasn't completed its first full charge-discharge cycle may not meet the device's internal voltage-state threshold for passing this check. The device reads the cell's state-of-charge report from the fuel gauge IC, and a fresh cell's calibration is off until the first cycle completes. Run one full charge from empty to 100% before placing the battery into clinical use.

Charge indicator stalls below 100% on the first charge

On first charge, the device's charge IC applies a conservative current limit to an uncalibrated cell — this is normal behaviour, not a fault. The fuel gauge hasn't established accurate capacity data yet, so the display lags behind actual charge state. The cell is still accepting charge; the indicator catches up as the fuel gauge IC updates. Allow the charge cycle to complete fully without disconnecting — the indicator will reach 100% once the IC finalises its capacity estimate.
