amperage of a 9 volt battery?

I got a free case sample from pac-tec, and it has a 9 volt holder built into the case. So if it were possible to power a screen and NOAC off a 9 volt for a decent amount of time, that might work pretty well. Being small and all.

I've used a 6V 800 mah battery setup for my NESp, and it lasts ~6 hours. So as long as the 9 volt has around that it could work. I've read that it only has a couple hundred milliamps on google, but the person wasn't sure. So if anybody could help me out on this, that would be great!

looks to be ~200mAh - 275mAh (from google)
These are 595mAh though

Ah well, I guess it won't work. It was just an idea. Thanks for the help though.

I'm not sure what the amperage is, but you arent going to power both the screen and the console for more than 30 minutes. It takes me 2 9volts to power the console alone for an hour.

Well in case you're still wondering, Energizer claims that their 9V batteries have a 650mAh capacity. It's in their "tech docs" section.

How about a Lithium 9 volt battery (the type designed to power smoke alarms for 10 years)

They're supposed to be something like 1 amp (1000mA) although here in the UK they're expensive.
