The crux of it is manual labor (not to mention liability if it doesn't work as expected).

Batteries packs are assembled as needed with fresh cells, new gasket, o-ring (for the antenna shaft), it is connected to a computer and status reads performed against various sensors, and then a RF transmission check, and the unit is water tested to a depth of 30 feet. At least this is what I gather from my conversation with ACR.
