Tracking Device Teardown
Ever wonder how your tax dollars were spent? I followed the ifixit.com link shown in the poster on a Dwellar's photoblog thread and came up with this. It's a teardown of a custom built FBI GPS tracker. Neat stuff.

Quote:
The device is powered by four lithium-thionyl chloride (Li-SOCl2) D cell batteries.
Each cell is good for 13,000 mAh! That's about double the capacity of the iPad 2's battery.
These cells are suited for extremely low-draw applications where longevity is needed, making them ideal for powering an always-on transmitter/receiver. Their service life is rated at 10 to 20 years.

Wow. If these things were rechargeable, I'd buy a dozen.
