How's Your Battery Doing?

"Do you have a Mac laptop?  Do you run on battery often?  Like to know more about how your battery is performing and the condition it is in?"  Jim Hamm asks.  He offers this link, saying, "You might take a look at the 'Battery Guru' app."But Jim, how does that compare with the iStat widget that comes up Function 4 key? Two shakes later we have his answer.  "Somewhat similar, I presume.  Here is the article in Small Dog Tech Tails #821 that describes more about the app." When you open that Tech Tails you'll also be entertained by the YouTube video of a truck running over an iPad.  Did you expect that?
