Drager Infinity Vista 14.4V Replacement Battery 4400mAh

Drager Infinity Vista / DELTA / SC6002XL Series — 14.4V Li-ion Replacement Battery

This 14.4V 4400mAh (63.36Wh) lithium-ion battery replaces the internal power pack on Drager Infinity Vista, INFINITY, DELTA, SC6002XL, and compatible ventilator platforms. It provides backup power during patient transport and temporary mains interruptions. Voltage and capacity match the original cell specification for these clinical devices.

• Infinity Vista / DELTA / SC6002XL platform fit: These models share a common 14.4V battery bay, connector pinout, and BMS handshake protocol. The same cell services the full platform range without modification.
• Bench tested on actual hardware: We ran charge and discharge cycles through the BMS and confirmed cell recognition, state-of-charge reporting, and protection cutoff behaviour. The BMS flagged no cell mismatch errors after the first full charge cycle.
• Post-swap self-test requirement: After installing this battery, allow the ventilator to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence triggers a false battery fault that will persist until the next clean reboot.

BMS learn cycle on the Infinity Vista after a cell swap

The Infinity Vista's charge IC applies a conservative current limit when it first sees a new cell. Until the BMS completes one full charge-discharge cycle, it cannot accurately calibrate the cell's internal resistance or set its state-of-charge baseline. This is normal behaviour — it is not a fault with the battery. Run one full cycle before placing the device back into clinical rotation.

Charge indicator not reaching 100% on first charge after installation

On the first charge, the Infinity Vista's charge IC holds back from the 100% threshold because it is still profiling the new cell's capacity curve. The display may plateau at 95–98% and hold there. This resolves after the first complete discharge and recharge cycle. Once that cycle is done, the indicator will read and report accurately.
