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

Click For Summary

Discussion Overview

The discussion revolves around finding information regarding the power and maximum current specifications for 9V and 1.5V DC batteries. Participants explore various battery types and their characteristics, including considerations for energy duration and alternative power sources.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests links for power and maximum current information for 9V and 1.5V batteries.
  • Another participant notes that the answer depends on the battery's size and chemistry, suggesting that more details are needed.
  • A link to a site with data on AA batteries is provided, although the participant is unsure if it covers other sizes.
  • A later post discusses ultracapacitors as an alternative for maximum power, highlighting their lower energy density compared to chemical batteries and questioning the duration of current needed.
  • There is a suggestion to consider whether a primary or secondary (rechargeable) battery is required.
  • One participant humorously suggests using an AC adapter instead of a battery and mentions the option of a lead-acid battery with a specific capacity.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple competing views regarding the types of batteries and alternative power sources. The discussion remains unresolved regarding specific power and current values.

Contextual Notes

Limitations include the lack of specific battery details from the original poster, which affects the ability to provide precise information. The discussion also touches on the distinction between maximum current and energy duration.

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?

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,
Dont forget to add me as your friend
