GE FRU Mini Telemetry Transmitter 2041703-001 7.4V Replacement Battery

GE FRU Mini Telemetry Transmitter — 7.4V Li-ion Replacement Battery (2041703-001)

This 7.4V 2600mAh Li-ion battery fits the GE FRU Mini Telemetry Transmitter and Mini Telemetry Transmitter, two portable patient monitoring units used for wireless cardiac and respiratory data transmission in clinical environments. It replaces OEM part numbers 2041703-001 and 2048469-001. Voltage, connector, and BMS communication protocol match the original GE specification.

• FRU Mini and Mini Telemetry compatibility: Both transmitter variants share the same 7.4V power rail, connector housing, and BMS handshake protocol — one cell fits both. The BMS on these units authenticates cell voltage on power-on, and this replacement meets that threshold from the first boot.
• Bench tested on actual hardware: We cycled this cell through full charge, load draw, and BMS negotiation on the transmitter platform. The BMS accepted the cell without fault flags, and charge termination triggered correctly at 8.4V with no thermal event.
• Post-swap self-test protocol: After installing this battery, let the transmitter complete its full power-on self-test cycle without interruption. The GE platform runs a BMS verification routine at startup — cutting power during this sequence writes a false battery fault that persists until the next clean reboot.

Why the GE Mini Telemetry Transmitter flags a battery fault after a confirmed full charge

GE's telemetry BMS uses a capacity authentication threshold calibrated to the OEM cell chemistry. A new replacement cell hasn't yet completed a learn cycle, so the BMS can flag a fault even when the cell sits at 8.4V. This is a BMS state issue, not a defective battery. Run one full charge-to-discharge cycle before clinical deployment — the BMS recalibrates its capacity estimate on cycle completion and clears the fault flag on the next charge.

Transmitter not powering on after the battery sat in storage

Li-ion cells self-discharge in storage, and if this battery shipped or sat for several months, cell voltage may have dropped below the GE transmitter's BMS recovery threshold — typically around 6.0V for a 7.4V nominal pack. Below that threshold, the BMS enters protection mode and blocks power-on entirely. Connect the battery to the GE charger and leave it for a minimum of 30 minutes before attempting to power on — the charge IC applies a low-current pre-charge to recover the cell to a safe voltage before returning to normal charge rate. If the charger LED does not change state within 45 minutes, measure cell voltage directly; below 5.5V, the cell will not recover.
