AA alkalines are 1.5 v and lithiums are the same. Rechargeables are 1.2 v so there are more incompatibilities with NiMH.
Edit: 8x to 10x is a bit over. That would be more for a low-drain device such as a wall clock. Expect a 1.5x to 2x improvement over regular alkalines in terms of raw mAH.

Just know the voltage is a sharp dropoff with lithium, so the typical battery life/meters won't be accurate with these (they detect voltage drop in traditional batteries).

longer life
stay at full voltage for 80-90% of stored energy
don't leak
handle cold/hot far better
flashlights are a bit brighter to start. but stay bright.
But there is a legitimate con -->The voltage drop off is a bit quick at the end of life, here are two examples.
1: Xfinity remote will show %100. When it finally warns of low battery, it's likely the remote will only have a few clicks left
2: Electronic door lock/deadbolt: Once the lock motor sounds like it's running slower you have only a short time before it won't open the door.
3: Flashlights - I got a few small flashlights that use a single AAA. It'll go from full bright to dim/off in about 15 minutes once it hits that drop off(2-3+hrs). An alkaline would be getting dimmer the entire time of use (1-2hrs).
