What are the best batteries(for size/price/weight/capacity)?

[tyromaniac]

I have recently found this battery which ways slightly over 1 pound (16.05 oz) for 50 dollars shipped
http://www.dealextreme.com/details.dx/sku.15973
it claims 10400mAh at 7.4 volts which seems excellent for its price.

or even this one which I found on the forums as posted by another user:

6000 mAh at 7.4 volts for 32 dollars plus shipping (minimum 6 dollar shipping charge).

Lithium battery (Supposedly 6600 mah) for 24.99 dollars with free shipping

With that said, are there any better deals on batteries that I don't know about? i mean, these battery looks like they could power some handhelds a long long time.

They are also gigantic.

Look into lithium.

#2 is good.

I used #2 in my N64 portable. I bought it from eBay, though, and it came with the charger. I took it apart and rewired it so it was about 1cm thick.

I used similar ones to that in my Dream Tablet. Here is a link to the ones I used. It doesn't say but those batteries are 6600mah. Only problem is that the cells are cylindrical so you couldn't really flatten them down too much as Mario did with his. But they are a great price.

Wait what, how did you, there are round cells in there. I have the 970, how did you get it so small, I'm having problems with the size for me.

[jjhammerstein]

The cells are 1cm in diameter, are they not?

[thewise1]

Mine are more like 1.5 cm. I suppose it's because your battery is 6000 mah and mine is 7400.

You really don't need over 4000mAh for anything 16 bit or below. That'll give you a good 7 hours of battery life or so.

More like 5, but yeah, it is a little overboard. But it is nice to have a really long lasting battery.

All I know is I used one of these. I may have gotten lucky with the square cells, though.
