A 9V alkaline battery can deliver a current od 6.7A for a few moments when it is fresh.
It'll deliver 9V or 6.7A, not both. Available power is more like 10-15W.

That is correct. It gives 6.7A into a very low resistance load or into a short.

Energizer have datasheets for all their batteries. Their 9V alkaline battery has six AAAA cells inside. Their internal resistance is 0.225 ohms each when new. So the 9V battery has an internal resistance of 1.35 ohms.
9V/1.35 ohms= 6.7A. The power is 9V x 6.7A= 60.3W. The power into a 1.35 ohm resistor is 15W for a moment.
Energizer's White Paper says that some little 9V batteries have an output of 10A.

Are you saying he posted this notification in this thread, and then deleted it? Damn strange!:rolleyes:
He seemed like a bright guy, but he came across as a little arrogant, and that combined with his erroneous info pretty much shot his credibility to hell. Too bad. :(
 
It is amazing that we can read a person's thoughts (hckr69) on an e-mail then it is deleted from the forum.
