About this replacement
Trotech IC60 / IC80 / IC100 / IC120 — 7.4V Li-ion Replacement Battery (3110003810)
This 7.4V 1600mAh Li-ion battery replaces OEM part 3110003810 in the Trotech IC60, IC80, IC100, and IC120 thermal imaging cameras. These are handheld infrared devices used in building diagnostics, electrical panel inspections, and HVAC surveys. It fits the same battery bay and connects to the same BMS handshake across all four models.
- IC60, IC80, IC100, IC120 shared platform: All four cameras run off the same 7.4V nominal rail and use the same physical connector and BMS communication protocol. Trotech standardised the battery across this IC-series lineup, so one cell configuration covers all four devices without firmware or connector differences.
- Bench tested on actual hardware: We ran this cell under combined load — detector heating element active plus display at full brightness. The BMS held the protection thresholds correctly and did not trip on the initial draw spike when the thermal sensor array initialised at power-on.
- Thermal detector warm-up protocol: After inserting a fresh battery and powering on, give the camera a full 60 seconds before taking measurements. The infrared detector needs the internal electronics to stabilise before it can produce an accurate thermal baseline — readings taken too early will drift.
Trotech IC-series shutting down mid-inspection on a new battery
The IC60 and its siblings draw current from two simultaneous loads: the thermal detector's heating element runs continuously, and the display backlight adds a secondary drain. Together these can pull enough current to trigger the BMS undervoltage cutoff earlier than the charge indicator suggests. This is more likely in cold environments where cell voltage sags faster under load. If the camera shuts down abruptly with the indicator still showing partial charge, the cell voltage has dipped below the BMS protection threshold — typically around 6.0V under load for a 7.4V Li-ion pack. Warming the battery to above 10°C before use reduces this sag significantly.
Thermal image accuracy degrading before the battery indicator shows low
Thermal measurement accuracy in the IC-series is voltage-sensitive — as cell voltage drops from 7.4V toward 7.0V under combined load, the detector's reference voltage can shift slightly, introducing drift in temperature readings before the camera signals a low battery. This means you may see measurements that look plausible but are off by several degrees. If readings start drifting or the image looks flat and low-contrast without any obvious cause, check the battery. Swap to a charged cell and allow the 60-second warm-up before retaking measurements.
