Ok so I have to make a PowerPoint on batteries for one of my classes and I can't find one of the questions on google or anywhere. So here's the question:

What's the difference of a 9v or AA battery compared to a computer or calculator battery?

electrical charge duh!! oh and probably the acids used in it.

Edit: Ok I get it acid is a chemical I wouldn't ok. I never took chemistry

They look pretty different to me.

Unless acid is a chemical than, no they don't have acid and the chemicals used are the same for any kind of battery.
Is this whole post a fail?

um acid is a chemical..

and trust me the chemicals used are NOT THE SAME. I will give you the fact it might be the same by the same company... but car batteries dont use the same type of chemicals as regular batteries... companies close gaurd their secrets so no one knows how they get the battery life they do.

9v has a nominal output of 9 volts, and they have acid in them (Unless rechargable) AA are 1.5 volts, same as above with acid. in my calculator i have a TI83 Graphing calculator i use AAA batteries, and those give off a nominal output of 1.5 volts. on my computer, i have a really ****ing awesome rechargeable battery, and i dont know the nominal output, but i like it lol.

All four are completely different. Have you tried researching the subject before asking the Pit?

AA batteries are 1.5 volts and have a zinc anode, a manganese dioxide cathode and use potassium hydroxide as an electrolyte (Alkaline ones, anyway).

9-volts contain 6 1.5 volt cells in series.

Laptops use rechargable Lithium Ion batteries, which have a high capacity and a light weight. They are, however, prone to the "Memory effect", which means that their capacity decreases over time.

Calculators should use solar panels. If they don't, then you're fucked

A Battery cell (alkaline) is around 1.5Vdc (AA, AAA, C & D) 9V batteries have 6 cells in them to add up to 9V (6 * 1.5). Computer batteries (not realtime clock ones)are Nickel Metal Hydrate or Ni CAD which can last a long time and be recharged. Most Calculators now can use akaline or in the case of my old Sharp, solar cells which need no batteries just enough ambient light.
Moving on.....

I'm pretty sure most scientific calculators and graphing calculators don't run off of solar panels.
