Very interesting video, all comes down to marketing and money as usual then :/

I did a test years ago with some AAA NiMH batteries from Energizer, Duracell, eBay and some others, granted a vibrator and toy car were not the best test subjects I was trying to see how long they really lasted compared to their capacities, they was meant to be the same. If I remember right the cheapest crappy ones came out top :lol:

I have seen things like this before...

I think manufacturers only generally make the AA size as they must be more popular. Then they sell adapters to make them fit C or D sizes..

Though I have also seen C batteries which have a AA bolted internally and those manufacturers do not make the D sized.

I have also wondered why the ratings are all out of whack like Dave says in the video... I mean D cell should be a lot higher capacity than AA or C but they never seem to be, at least not when I looked a few years back.

But it is likely down to cost as well.. Have to think in terms of the idiot public, where one manufacturer selling a D cell less than half price of another manufacturer, then they will almost certainly go for the cheaper one.. So then other manufacturers have to fiddle their products to compete at the same price point.

I think I wanted to buy a powerful LED torch while ago.. I think I gave up as the D cells either did not exist, or they was not more powerful than the C cells.. which did not really seem a worthwhile jump from a AA cell.. Either cost or capacity wise.
