What is the best battery for the nintendo Wii? i need a 12v battery and it would be nice for rechargeable and as small as possible, also if i would like to have the much playtime as possible. Im making my Wii protable http://www.wiicade.com/forum/viewtopic. ... sc&start=0 just like Ben, but i want mine battery powered also.

It's going to be expensive, but look for a Li-Ion or Li-Po battery of 4000mAh+. These came up in a quick search: http://www.batteryspace.com/index.asp?P ... ProdID=919

The second one looks like a good bet.
You might want to continue my Google.

you are going to want to use an external laptop battery rated at around 80-120 wH (watt hours). They run up to around $100-$150.

If you want cheap, you can get a lead acid battery (http://www.batteryspace.com/index.asp?P ... tegory=775)

But they're heavy and rectangular.

They'll work fine, its just the size.

And you know, the acid.

I think you'll want at least a 5Ah one, but I'm not sure what the Wii draws, so I don't know how long what would last. You're likely going to be carrying your Wiip in a bag from place to place, so you can just leave the clunky battery in there and have a wire going between them. Only problem is that lead acid batteries can't be discharged too low. I think its something like 50% of capacity is the lowest that they should go to be safe and not damage them.

the wii draws 17watts

powersupply says it outputs 12V at 3.7amps. I would guess that the wii doesn't draw all the amps the powersupply pumps out.

I hope you're also looking at the weight.

Although the size may be small, they're really heavy.

Here's some examples, straight from batteryspace:

12V 7.5 AH $20
Dimension (LxWxH) 151mm (5.95") x 65mm (2.56") x 94mm (3.70")
Weight 2.54 kg (5.60 lb)

12V 10 AH $40
Dimension (LxWxH) 151mm (5.95") x 65mm (2.80") x 111mm (4.48")
Weight 3.3 kg (7.28lb)

As for the power supply, is it a regulated switching one or a standard unregulated transformer one? If it's light, then it's probably circuitry and not a heavy metal coil. If it's light, 3.7 A is not what a Wii uses.

What would be the point if they were not?

Yes they are

IMO 60wH should be plenty, if the Wii truly only uses 20W, then it should last 2-3 hours on that. $50 on ebay.

The current gen of systems are mostly 'semi-portables' (no batteries), due to their high power requirements. I think 2-3 hours is a pretty nice compromise.
