About this replacement
CorDex ToughPIX I / ToughPIX II Trident / TP2410XP — 3.6V Ni-MH Replacement Battery (CDX2400-011)
This is a 3.6V, 700mAh Ni-MH replacement battery for the CorDex ToughPIX I, ToughPIX II Trident, and TP2410XP thermal imaging cameras. It replaces OEM part CDX2400-011 and fits the original battery housing without modification. Capacity figure is taken directly from product data — 2.52Wh total stored energy.
- ToughPIX I, ToughPIX II Trident, TP2410XP compatibility: All three models share the same 3.6V single-cell Ni-MH pack format, connector pinout, and BMS handshake protocol. The thermal detector heating element and LCD draw from the same voltage rail, so the BMS threshold and cutoff logic are identical across the range.
- Bench tested on actual hardware: We cycled this cell under combined detector-plus-display load on the ToughPIX platform and confirmed stable voltage delivery through the BMS protection window. The BMS tripped cleanly at the correct low-voltage threshold with no false cutoffs under steady thermal detector current draw.
- Detector warm-up on fresh install: After fitting a new battery, power on the camera and wait a full 60 seconds before taking any thermal readings. The microbolometer detector requires the internal electronics to reach thermal equilibrium before it can establish an accurate baseline — readings taken during that window will drift.
ToughPIX shutting down mid-inspection on a new or recently charged battery
The ToughPIX draws current from two simultaneous loads — the LCD backlight and the thermal detector's internal heating element. That combined draw is higher than either load alone, and a Ni-MH cell that has sat unused for months will show a temporarily elevated internal resistance even at full state of charge. The BMS reads a voltage sag from that resistance spike as a low-cell condition and trips the cutoff. Running one or two full charge-discharge cycles through the camera's own charger lowers the internal resistance and eliminates most of these false shutdowns.
Thermal image accuracy degrading before the low-battery indicator appears
The microbolometer detector in the ToughPIX is voltage-sensitive — measurement accuracy begins to fall before the cell voltage drops far enough to trigger the low-battery warning. This means you can be looking at a display that shows adequate charge while the detector is already outside its calibrated operating range. In practice, thermal accuracy degrades noticeably below approximately 3.2V on the cell. If spot temperature readings seem inconsistent or the image looks flat before any warning appears, replace or recharge the battery rather than continuing the inspection.
