For those of you who have not heard of these, the new LifePO4 A123 Systems

I looked at the 18650 on the A123 website and compared it with the AA Duracell rechargeable in my flashlight. A123: 1.1Ah Duracell AA:2650 mAh. Am I right in concluding that the AA has over twice the capacity? Does 2650mAh equal 2.6 Ah?
