Maximum current for 9V and 1.5V DC batteries

[tefavolc]

i need link for the power or the maximum current for dc battery 9 and 1.5 voltage ..if anyone know please share it ??

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:

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
