Questions about batteries from a newby.

I'm sure this question has been talked about, but I'll ask all the same. Please pardon my ignorance if the questions are evidence of a rank amateur!

1. AAA, AA, C, and D all are 1.5 volts yet are different in size. Question is, does one D size battery have longer burn time over a AAA? The logical choice, to me, is yes.

2. You stick 6 AAA together for 9 volts. How does that compare to a 9 volt battery?

3. Does the same volts from a combination of lithium batteries have more 'power' than the same volts from a combination of alkalines?

Thanks for your replies.

AAAA 595mA at 1.5v
AAA 1150mA at 1.5v
AA 2750mA at 1.5v
C 8350mA at 1.5v
D 18000mA at 1.5v
123 1300mA at 3v
9v 595mA at 9v (notice it is the same mA as AAAA cell)

The mA is how many miliamp hours it holds

You can see if you use 6 AA batteries you get 9v at 2700mA instead of 9v at 575mA, it would last approx 5 times longer.

Lithium batteries can let their power out faster. If you have something that uses a lot of power you will be better off with lithium vs alkaline. Alkaline just can't produce it power as fast as lithium. NiMH can produce power much faster then alkaline, but they run at 1.2v instead of the 1.5 of alkaline or the 1.7 of lithium.

I'm sticking that info in the FAQ! You know - the FAQ that doesn't exist yet...

Brock, . . . that you VERY much for your answer. That helps me out quite a bit. I believe I will print that off for my reference!

Yeah, a Newby FAQ area would be a great help.
