Nope - LOL.
So, yes, those are both standards!
And a Mini, WITH the extension cap, is a teensy bit shorter than one of those WITHOUT the extension cap.
Which, by the way, is how I use my "one of each" most of the time: Mini with extension, standard without - so they both have an 18490 battery. It's nice though that I CAN go tiny 18350. or big 18650, when I want...
THAT IS A GREAT LOOKING PAIR!!
Which is which?
Do these pics looks sideways to anyone??
Grrr....
Actually maybe it's easier to match up the lines for comparison?
