No idea what Varta has done with the silver Professional batteries, but they have power without end. We use the Triple-A for the radios of our children - despite the hunger for energy to keep the cell seemingly eternally performance. Use the Double-A variant for Blitzbertieb in my Speedlite in the EOS 5D. Also, since I get it not plattgeblitzt. Rarely need to the gas station / charger, and I am surprised every time by a photo gallery that still juice in it. Did the more experienced as with any other NiMH battery - just great! Would not want to buy another memory more, despite the rather high price. Can you recommend high full!
