Bionet BM7Vet HS111202-BNT Replacement Battery 10.8V

Bionet BM7Vet Optional — 10.8V Li-ion Replacement Battery (HS111202-BNT)

This 10.8V, 6800mAh Li-ion battery replaces the original power cell in the Bionet BM7Vet Optional portable veterinary patient monitor. It fits the BM7Vet Optional directly and matches OEM part numbers HS111202-BNT and SCR18650-F22-032PTCW. Capacity is rated at 73.44Wh, consistent with the original specification.

• BM7Vet Optional platform fit: The BM7Vet Optional uses a fixed 10.8V three-cell Li-ion configuration with a BMS that validates cell voltage and internal resistance at startup. This replacement matches that configuration — voltage rail, connector pinout, and BMS communication protocol align with the original pack.
• Bench tested on actual hardware: We cycled this cell through charge, standby, and load conditions representative of continuous patient monitoring. The BMS passed the startup handshake and held voltage within spec under sustained draw. No false fault codes were triggered after the first full charge cycle.
• Startup self-test protocol: After installing this battery, let the BM7Vet Optional complete its full power-on self-test without interruption. The device runs a BMS verification sequence at boot — cutting power mid-sequence generates a battery fault flag that persists until the next clean reboot, not until the next charge.

BM7Vet Optional not completing boot sequence on a new battery

The BM7Vet Optional runs a BMS verification check during the boot sequence that compares cell voltage and internal resistance against OEM baseline thresholds. A fresh replacement cell that has not completed its first full charge-discharge cycle may present resistance values outside the expected window, causing the device to stall mid-boot. This is not a hardware fault — it is a calibration gap between a new cell and the device's learned parameters. Run one full charge from flat to 100% before placing the unit into clinical use, and the boot sequence will complete normally on subsequent power-ons.

Low battery alarm triggers immediately after a confirmed full charge

The BM7Vet Optional's low-battery alarm threshold is calibrated to the internal resistance profile of a conditioned OEM cell. A new replacement cell has slightly elevated internal resistance before the first cycle is complete, which the charge IC reads as insufficient capacity even when the cell is at full voltage — typically 12.6V at the pack terminals. The alarm clears after the battery completes one full discharge and recharge cycle, allowing the BMS to update its state-of-charge model. Discharge the unit normally under monitoring load, charge fully to 12.6V, then recheck the alarm status before returning the device to service.
