Find Power & Current Info for DC Battery 9V/1.5V

AI Thread Summary
The discussion focuses on finding information about the power and maximum current for 9V and 1.5V DC batteries. The maximum current varies based on battery size and chemistry, with suggestions to provide more details for accurate information. Resources like PowerStream and Battery University are recommended for further research. Ultracapacitors are mentioned as a high-power alternative, though they have lower energy density compared to chemical batteries. The conversation also touches on the choice between primary and secondary batteries, as well as the option of using AC adapters for power needs.

i need link for the power or the maximum current for dc battery 9 and 1.5 voltage ..if anyone know please share it ??
 
Engineering news on Phys.org
There is no one answer for this. It depends on the size of the battery and the type (chemistry) of the battery. You need to give more details.
 
This site has some good data on AA batts:

I thought they dealt with other sizes too, but I can't find anything in quick search mode. Maybe a little more digging will turn it up.

If maximum power is truly your only concern, and not duration (i.e energy), then ultracapacitors are the leading technology though their energy density is an order of magnitude less than a chemical battery. So the first question is 'maximum current' for how long? See, e.g., here:
http://en.wikipedia.org/wiki/File:Supercapacitors_chart.svg

If you truly want a battery, can you use a throwaway (primary) or do you need a rechargeable (secondary) battery?

This site might also provide some useful background:

thnx all for help
 
If you want power..throw avay the battery and get an ac adapter

or buy a lead acid battery of 10ah atleast

Go green think green
Ethan,

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
