What this battery replaces

This Cameron Sino lithium-ion pack replaces the original power source for FLIR 37888, 40798, CA-100, CA-300, Micro CA25 and Micro CA-300 inspection cameras. It delivers 5200mAh at 3.7V for 19.24Wh of capacity. The fully decoded chip communicates with the host exactly like the factory cell. Builders servicing these specific thermal imagers will find a direct fit.

Runtime on a long inspection job

The 5200mAh rating supports extended continuous operation during thermal surveys or pipe inspections. Protection circuits guard against overcharge, over-discharge, over-voltage and short circuits to preserve cell health over repeated cycles. Performance stabilises after two or three full charge and discharge sequences. The pack measures 71.40 x 39.45 x 21.00mm and weighs 150.0g.

Check before you order

Verify the model number on your camera body and the part number on your existing battery against the list 37888, 40798, CA-100, CA-300, Micro CA25, Micro CA-300 and part numbers 990514, 990596. Ensure the connector mates securely when installed. Do not charge with low-quality third-party adapters. Store below 60°C.

Questions about this item

How much heat does the 5200 mAh lithium-ion pack generate during a full day of thermal-camera use?

The 3.7 V, 19.24 Wh cell is designed for inspection cameras and includes over-charge, over-discharge and short-circuit protection to limit temperature rise during extended operation.

What charger or adapter must I already own to recharge this 37888-compatible battery?

The pack uses the camera's original charging circuit; a low-quality third-party adapter is discouraged because it can shorten the battery's life.

Will this replacement cell work in my older Micro CA25 inspection camera that originally shipped with part number 990514?

Yes — the decoded chip matches the original specification for models 37888, 40798, CA-100, CA-300, Micro CA25 and Micro CA-300.
