This article is a bit odd. It does mention the "B" vacuum tube batteries you linked in that Wikipedia page, but B-size batteries are not the same thing. The article kinda mentions this ("voltage range of 45 to 90" vs 1.5v) but overall just conflates the two.

I think the oddness is the LLM content generator conflating information about the 2 types of batteries.

It's almost as if the shortest possible designations are most likely collision candidates.

Those aren't B batteries, they're "B" batteries. You can tell because there's also a photo of a "C" battery that isn't cylindrical.

There's a photo of an actual B battery here: https://en.wikipedia.org/wiki/File:B-AA-battery.jpg

The B battery referred to in the article is a vacuum tube battery.

The B battery you linked, is an carbon-zinc/alkaline battery and against that the comment says -

> Most commonly found within a European 4.5-volt lantern battery. Not to be confused with the vacuum tube B battery

This is a latern battery. You put other batteries in it. That's why it's called the 3R12. There are 3x R12 batteries in it.

I remember seeing something like these in roadwork flashing lanterns.
