Panasonic CR123A

[ScottsoSmith]

I've noticed the newer Panasonic CR123A batteries are silver and black, whereas the Panasonics were traditionally blue, black and gold. Does anyone know if the technical performance of the battery has changed much?

The black and silver are the industrial model, the other is a regular model. I don't know the difference or why there's such an industrial model. Manufacturers make an industrial model also for alkalines.
