Hey guys can you help me out here...

I created a battery out of these materials

 

NH4Cl, MnO2, Zinc strips, carbon rod ...

 

What i did is make a 4 M solution of NH4Cl, by putting 20 grams of it into 85 ml of water... then I dipped a felt pad into it

 

Then I got 4 grams of the MnO2 and spread it onto the felt pad

 

Then I wrapped it around a carbon rod

 

Finally I covered the felt pad with multiple zinc strips ...

 

Finally I got an average of a 1.5 volt from this, using a voltmeter, yet when I connect it to a light bulb, it doesnt flash, but flashed from a 1.2 volt battery ...

 

Can anyone tell me why this happens ? ... Is it because the zinc strips are small... should it be one big piece ?

What is amperage of your battery?

If i measured it correctly I have a 300 micro amp.. the 200 part on the voltmeter maxed out !

So I actually have a .325 milli amps , I realize now that that is the problem

Do you know how I can solve my problem ?

You can get more current by placing batteries in parallel.

I would have to have a lot of batteries though... I would need a hundered times stronger current and I am limited to a small quantity

Indeed. I had a thought that I might power a laser diode with a potato battery system, but realized it would take hundreds of cells to give me the current I needed.
