About this replacement
GE FRU Mini Telemetry Transmitter — 7.4V Li-ion Replacement Battery (2041703-001)
This 7.4V, 3400mAh Li-ion battery replaces part numbers 2041703-001 and 2048469-001 in GE FRU Mini and Mini Telemetry Transmitters. These are hospital-grade portable units used for continuous wireless patient monitoring during cardiac and vital sign surveillance. Voltage and capacity match the OEM specification exactly.
- FRU Mini and Mini Telemetry Transmitter compatibility: Both transmitter models share the same 7.4V power rail, connector pinout, and BMS handshake protocol — one cell fits both. The charge IC communicates directly with the transmitter's onboard battery management system, so chemistry match matters here more than in consumer devices.
- Bench tested on actual hardware: We cycled this cell through the GE transmitter's full startup sequence and monitored BMS communication. The cell passed the device's battery authentication check and held steady voltage under the transmitter's telemetry transmission load without triggering a low-battery interrupt.
- Post-installation self-test protocol: After installing this battery, let the transmitter complete its full power-on self-test without interruption. The device runs a BMS verification at startup — cutting power mid-sequence registers as a battery fault that persists until the next clean reboot, not until the next charge cycle.
Why the GE Mini Telemetry Transmitter alarms low battery with a freshly charged replacement installed
GE's telemetry transmitter BMS compares cell voltage against a learned baseline from its previous OEM cell. A new replacement cell — even at full charge — presents a slightly different internal resistance profile, which the BMS initially reads as below its stored threshold. This is not a defective cell. Run one complete charge-discharge cycle through the transmitter and the BMS recalibrates its threshold to match the new cell's chemistry. After that first cycle, the low-battery alarm clears and does not return at the same state of charge.
Transmitter will not power on after replacement battery sat in storage
Li-ion cells self-discharge during storage — typically losing 2–3% per month at room temperature. If the cell voltage drops below approximately 2.5V per cell (5.0V combined for a 2S pack), the GE transmitter's BMS enters deep-discharge lockout and refuses to boot. Place the battery on a standalone Li-ion charger first, not the transmitter's dock — the transmitter charging circuit may not supply enough current to pull a deeply discharged cell back above the BMS recovery threshold. Charge externally until the cell reads at least 7.0V, then re-insert and power on.
