Powering a genesis, 9V battery?

[doonbugie]

I'm wondering if I could run a genesis on a 9v battery, I dont really care what else I can run it on other then if I can run a genesis model 1 for even a minute or two.

Out of boredom, I've tried it on my Nomad, I never got it to fully power up though, it instantly read low battery, but that may have been because it was not fresh. With a new battery, it might work, but then again, it may explode from the high discharge rate.

I dont think it would fry it, Because with batteries, I think It draws what it needs. And Nomad's and Genesis Model 1's Voltage rating is 9v.

I know you can easily run a Genesis 3 off a 9V battery through the regulator. Not sure about any of the other models.

Edit:

From "WHATS THE MAX VOLTAGE FOR A SEGA GENISIS MODEL 2"

~25v technically (if you want enough heat to last through an Alaskan winter). Input voltage gets fed a 7805 voltage regulator, so the minimum is 7.2v.

HOW WAS THAT ANSWER WAS THAT GOOD

So I guess the Genesis 2 has a 7805 as well. For the record, I don't think you'd fry any game console using a 9V battery.

I should have been less ambiguous in my statement, the battery *could* explode, but then again, it might not. Anyways, in theory it should work, but reality is mean sometimes.

yeas, the Genny 2 has a 7805.

Actually, 35v max, 5.9-6.5 (differs on all of my 7805's) minimum for the 7805.

Alkaline batteries are not that reactive. If you can set fire to steel wool by shorting it across the terminals with no real damage to the battery, you're not going to get one to catch fire by simply trying to power something too big to run off it.

Anyways, considering the weird power supplies that I've seen actually power a Genesis, a 9Volt alkaline battery should work. I have bought a Genesis 2 from a garage sale that came with a 4.5Volt labeled power supply. I had thought it got bundled with the Genesis 2 by mistake, but decided to try it anyway, and it actually worked. Either there is a Schlotky(sp?) diode that bypasses the 7805, or the power brick actually outputs more than 4.5Volts.
