Drager Infinity Vista Replacement Battery 14.4V 6800mAh

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

This 14.4V 6800mAh lithium-ion battery replaces the internal power pack in Drager patient monitoring systems including the Infinity Vista, Infinity, Delta, and SC6002XL. It supports portable operation and provides backup power during patient transfers or brief power interruptions. No OEM part number is published for this cell — fit is confirmed by voltage, form factor, and connector alignment.

• Infinity platform compatibility: The Vista, Delta, and SC6002XL share the same 14.4V battery bay and connector pinout across the Infinity monitor line. The BMS communication protocol is consistent across these models, so one cell covers the full listed range without modification.
• Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle and confirmed the BMS handshake completed without fault codes. The protection circuit held charge termination at the correct voltage and passed the device self-test on the subsequent boot.
• Post-installation startup protocol: After fitting this battery, let the Infinity monitor complete its full power-on self-test without interruption. The BMS runs a chemistry verification at startup. Cutting power during that sequence logs a false battery fault that persists until the next clean reboot cycle.

Why the Infinity Vista alarms low battery immediately after a confirmed full charge

The Infinity platform sets its low-battery alarm threshold against a stored BMS capacity baseline. A new cell has no baseline yet, so the monitor's charge IC applies a conservative limit on the first charge cycle and the reported state-of-charge reads lower than actual. The BMS calibrates its internal model after one complete charge-discharge cycle. Once that cycle is done, the alarm threshold aligns correctly and the false low-battery warning clears.

Infinity monitor fails self-test after battery sat in storage

Lithium-ion cells self-discharge during storage. If this battery has been sitting for several months, cell voltage may have dropped below the Drager BMS recovery threshold — typically around 10.5V for a 14.4V nominal pack. At that level, the BMS locks out charging as a protection measure and the device cannot complete its boot sequence. Connect the monitor to mains power and leave it on charge for at least four hours before attempting to boot on battery alone. If the charge indicator begins climbing, the BMS has cleared the lockout and recovery is underway.
