Agfaphoto CR123A 3V Lithium Battery CR123

These last for ages in my trail camera, way longer than the generic store brand ones did. Really solid 3V power for consistent night shots even in cold weather.

I was a little worried these might not last as long as the CR123As I've used before, but after a month in my digital camera they're still going strong. The lightweight lithium design makes them easy to pack as spares.

Picked these up for my old film SLR and they've held a steady charge through a couple of rolls now. Only gripe is the price per cell, but they're genuinely lightweight and haven't leaked like some cheaper ones I've tried.
