Hi Element14 Community!
Traditional alkaline batteries tend to "die" at the most inconvenient times. I used to I have them in devices like wireless mouse and keyboards, and it felt that the batteries were draining fairly quickly, catc...

This was a surprise!
Going away for a bit, and charged up my camera batteries, only to see this; you can see the left battery has a curved surface, it's not flat like the one on the right.
I measured the thickness at 20.4 mm, compared to 18.5 mm ...
