Optimas Ah is pretty high and usually only slightly smaller than other comparable batts. Thats because the batt consists of 6 cylinders instead of a rectangle so its actually smaller in size which is why its Ah is slightly smaller.

i was told once that the cylinders and gel medium are what makes the Ah lower because it can't make the chemical reaction fast enough--same overall info though (optimas are worse than standard batteries for high, constant, draw), but i might have been misinformed..
