Battery consumption

So heres the sich, I am working on a Sega Genesis Revision, using a Sega 1 mobo. The mobo requires 9V and the LCD requires 12V. What battery should I use to power the thing maximum 1 hr, and minimum 30 MIn. I just wanna know that. No altering the mobo and such. I got a deadline for this, sry .

You couldve just put this in your other thread. And use something with atleast 2000mah and you'll get good life.

according to POD, it can take anywhere from 7.3-36 so just get a 12v battery. what screen are you using? it might be able to be modded to take 7.2v so you could get a 7.2v battery which are smaller and lighter than 12v

any suggestions on what combination of batteries would give me that power

a bunch of AAs or 2 rc car battery packs would give you a little more

10 rechargable AAs or see my previous post, i edited it

I like the idea of 2 Rc car batteries. Can someone elaborate on that, like how much power it has and such.

my LCD doesnt have a 7805, and i cant mod it, cuz its good and cost me 100$

Oh, yeah, and about the 10 rechargable batteries, can i just use 10 normal Alkaline batteries as a substitue. I know that its possible but would it work, good enough.

rechargables are 1.2v so that's 12v. normal AAs are 1.5v so you only need 8 of them but you should go with rechargable so you don't have to buy a bunch of new batteries every time they run out

Genesis 1 has a 7805 (that's what the vertical heatsink and TO-220 are) and runs off 5v. the power button is connected to the 9v in line but aside from that it should all be straight from the 5v output of the 7805.

thanks turbo tax 1.0 and dagguy. I gonna fuse both of your ideas, turbo tax's dc recharger, with dagguy's 8/10 AA batteries.

before i start soldering, let me spicify the question. So 8 AA alkaline batteries can power a genesis that requires 9 V and a LCD that requires 12V. for 30-60 minutes. you know just wondering

Depends on the capacity of the batteries. Test the draw on the system and screen combined.

You do know you'll need to spend 6 dollars everytime you want to play your Genesis?
