What's the Difference Between mAh Ratings of Bateries? Have been reading (here and elsewhere) regarding the lithium ion batteries used in electronic devices and am getting a real education this afternoon; however, I can not find (other than longer life) what is the difference between the standard 1130 mAh and the 2200 mAh batteries, for example. By this I mean does one have 25% or 50% more power than the other considering "normal use". How am I to inerpret the mAh other than longer life as mentioned...guess I just a different set of numbers to visualize, and to rationalize my intended purchase! Comments welcome and accepted in advance.
