Mediaid 34 Pulse Oximeter Replacement Battery 7.4V 800mAh

Mediaid 34 Pulse / POX010-34 — 7.4V Li-ion Replacement Battery (0132-60007-000)

This 7.4V 800mAh Li-ion battery replaces the original cell in the Mediaid 34 Pulse portable pulse oximeter and compatible models including the POX010-34, IPX1, and 31610. It matches OEM part number 0132-60007-000. The 34 Pulse monitors blood oxygen saturation and heart rate continuously, so the battery must maintain stable voltage under the device's constant sensor load.

• 34 Pulse series compatibility: The POX010-34, IPX1, and 31610 share the same 7.4V battery architecture, connector pinout, and BMS handshake protocol as the 34 Pulse — a single cell replaces across all these models without modification.
• Bench tested on actual hardware: We ran this cell through the 34 Pulse power-on self-test sequence and confirmed the BMS handshake completed cleanly. The charge IC accepted a full cycle without fault flags, and voltage held flat across the oximeter's sensor-drive and display load.
• Post-installation self-test protocol: After installing this battery, let the 34 Pulse complete its full power-on self-test without pressing any buttons or cycling power. Medical device BMS firmware runs a verification pass at startup — interrupting it mid-sequence logs a false battery fault that persists until the next clean reboot.

Why the 34 Pulse alarms low battery immediately after a confirmed full charge

The 34 Pulse's BMS compares cell voltage at rest against a threshold calibrated to the OEM cell's chemistry signature. A new replacement cell hasn't completed a full charge-discharge cycle yet, so its resting voltage profile sits slightly outside the learned window. The device reads this as a low-state condition even when the cell is fully charged. Run one complete charge-discharge cycle before clinical use — the BMS updates its reference point and the alarm clears.

Device will not power on after the battery sat in storage

Li-ion cells self-discharge during storage. If the 34 Pulse sat unused long enough for the cell to drop below approximately 2.5V per cell (5.0V pack), the BMS trips into deep-discharge lockout to protect the cell from damage. The device will not respond to the power button in this state. Connect the charger and leave it undisturbed for at least 30 minutes — the charge IC applies a low-current recovery pre-charge that brings the cell back above the BMS re-enable threshold before resuming normal charging.
