Cameron Sino 66410-00 2400mAh 3.7V dry cell battery

Direct replacement for Trimble Juno devices

This Cameron Sino battery replaces the Trimble 66410-00 pack used in Juno SA, SB, SC and SD units. It matches the original 2400mAh capacity and 3.7V voltage so survey and test equipment runs without modification. The integrated chip is fully decoded to communicate with the host device exactly like the factory cell. Buyers who need a different form factor or higher capacity cannot use this pack.

Thermal and power behaviour in daily use

Lithium-ion chemistry delivers the rated 8.88Wh at 3.7V with low self-discharge during field work. The built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits, keeping temperatures stable under normal survey loads. No active cooling is required and the cell operates silently. Users who expect hot-swap capability or extended high-drain cycles beyond the rated capacity will not find those features here.

Build quality and connector implications

The pack measures 66.52 x 42.86 x 12.00mm and weighs 52.5g, matching the original mechanical envelope for a secure fit in the Juno battery bay. A shock-absorbing foam insert protects the cell during transport and installation. The connector aligns with the Trimble 66450-00 and BA-1405206 pinout so no adapter cables are needed. Technicians who require screw-terminal connections or a different keying arrangement must look elsewhere.
