Youssef15015 Posted April 3, 2014 Share Posted April 3, 2014 (edited) 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 ?

Sensei Posted April 3, 2014 Share Posted April 3, 2014 (edited) What is amperage of your battery? Edited April 3, 2014 by Sensei Link to comment Share on other sites More sharing options...
Youssef15015 Posted April 4, 2014 Author Share Posted April 4, 2014 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 Link to comment Share on other sites More sharing options...

swansont Posted April 20, 2014 Share Posted April 20, 2014 You can get more current by placing batteries in parallel. Link to comment Share on other sites More sharing options...
Youssef15015 Posted April 20, 2014 Author Share Posted April 20, 2014 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 Link to comment Share on other sites More sharing options...

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.
