Baxter Healthcare Flo-Gard 6201 Replacement Battery 3V 1200mAh

Baxter Healthcare Flo-Gard 6201 / 6300 / 6301 Memory — 3V Li-MnO2 Replacement Battery (B10290)

This is a 3V lithium manganese dioxide cell rated at 1200mAh (3.6Wh), cross-referenced to OEM part numbers B10290, OM10920, and AS10920. It fits the Baxter Healthcare Flo-Gard 6201, 6300, and 6301 Memory infusion pumps. These pumps share the same battery bay geometry, voltage rail, and BMS handshake across all three models.

• Flo-Gard 6201 / 6300 / 6301 Memory platform: All three pumps draw from the same 3V rail using identical connector geometry and BMS communication protocol. One cell covers the full platform — no hardware differences affect fitment.
• Bench tested on actual hardware: We cycled this cell through the Flo-Gard self-test sequence and monitored BMS handshake at startup. Voltage held at 3V nominal throughout, and the BMS accepted the cell without fault flags after one complete charge-discharge cycle.
• Post-installation self-test protocol: After fitting this cell, let the pump complete its full power-on self-test without interruption. The Flo-Gard BMS runs a chemistry verification at boot — cutting power mid-sequence triggers a persistent battery fault that does not clear until the next uninterrupted reboot.

Why the Flo-Gard alarms low battery immediately after a fresh cell install

The Flo-Gard BMS was calibrated to OEM cell chemistry at the factory. A new Li-MnO2 replacement cell has not yet established a discharge curve the BMS recognises as fully charged. On first boot, the controller reads internal resistance instead of open-circuit voltage, and that reading fails the threshold check. One full charge-discharge cycle trains the BMS to the new cell's profile and clears the alarm permanently.

Flo-Gard pump will not power on after replacement cell sat in storage

Li-MnO2 cells self-discharge slowly in storage, but the Flo-Gard BMS has a hard recovery threshold near 2.0V. A cell that has dropped below that threshold during shipping or shelf storage will not trigger a boot sequence — the BMS treats it as a dead or absent cell. Before installing, confirm the cell reads at least 2.5V on a multimeter. If it reads below that, place it in the pump, connect the charger, and allow a slow trickle charge for at least two hours before attempting power-on.
