On a planet where we can’t decide on the size of a sheet of paper, what side of the road to drive on, or what household current should be (and what an outlet should look like). How in the world can we have a planet-wide standard for batteries? AA/AAA/C/D sized batteries are the same across the globe. How did this happen?

AA/AAA/C/D is a standard. You are wondering why 1kg in one state is 1kg in another.
But there are a multiload of different batteries in different sizes, best example are laptops, their batteries arent interchangable because they vary in size and load.
Standards and norms are used for customers to know what they are buying and dont “unify”, its only there to know that if you need a Battery with AAA, you can use any with AAA.
