2.5 amp-hrs is a reasonable capacity expectation for a rechargeable AA.

That means it can put out half an amp for 5 hrs, or one amp for 2.5 hrs.

Since you are talking about an Energizer battery then why not see its datasheet on Energizer's website?
It works pretty well with a current up to 2.5A but is not so good at 5A.

Ok let me get this straight:

My robot that I am using it for (A line following robot called linebot, which is a original name i know) uses about 200mA. So, could I run my 9.6 volt (1.2 x 8 = 9.6) 20 aH (2.5 x 8 = 20) Battery pack for 100 hours? Wouldnt it just use all 20 amps, or would it use the mA it needs?

If you use 2500mA cells in series, then the battery has a 2500mAh rating.
At 200mA the battery will last for 2500/200= 12.5 hours.

A circuit takes only as much current as it needs. Your robot will use a low current when it is stopped and will use a high current when it is accellerating up a hill.
