When it comes to recording digital audio in the field, I have a paranoia about batteries. Whenever I let down my guard, Murphy’s Law seems to raise its ugly head. The batteries in the recorder die at precisely the magic moment during an unrepeatable event. How do you avoid such power loss calamities?
The portable video industry began in the mid-1970s using nickel-cadmium batteries with primitive charging circuits. Enough Ni-Cad batteries for one-day’s use often weighed more than the heavy first-generation portable broadcast camera itself. Today, lithium-ion batteries have improved life dramatically. But on the horizon is a new battery technology — solid-state — which promises greater safety, longer life and faster charging.
The U.S. Department of Transportation (DOT) and Federal Aviation Administration (FAA) have announced a new Interim Final Rule banning the transportation of lithium-ion batteries in passenger aircraft cargo.
