The 18650 is designed for a completely different purpose than the 26650... the 26650 are also sold in cardboard sleeves and bundled to run power tools in 18Volt configurations.
I think you mean your AA is 1.2 Volts at 2650 mAh which would be the same as 2.6 Ah... not sure where your question is leading?
