Introduction: Easy Conversion : AA to C (Or Any Other) Cell

Now, there are already many instructables for the same purpose, but, there isn't any this simple!!!....

After reading this, you shall be able to transform any cell type to any other cell type, given that the former is of the smaller size!!!...(I needed to transform an AA cell to C type for my wall clock...)


Just follow these simple steps  (Just read the words written in caps in case of hurry!!!) :-

1) Take the cell you intend to transform (note that the cell taken MUST be of smaller size than the one in which it is required to be transformed!!!).
2) Take some old newspaper or ant other rag paper.
3)Cut out stripS of width same as the height of the cell and length as long as possible.
4) Now just stick the one end of the strips on the cell. And then, just go on and wrap the cell continuously with the strips, until the cell has width approximately as that of the required cell.
5) Done!!!..... you are now the proud owner of a newly transformed cell/battery !!!.... :D

In case required, one can wrap the cell finally with some other coloured/printed paper to make the cell look somewhat the real type...

Costs involved : Not a single penny!!! ......Newspaper was just a rag....


THANKS FOR TAKING OUT TIME TO READ THIS INSTRUCTABLE!..... :D

This is OK for this low current application like a clock or a radio. But for higher current draws such as motors/relays I doubt it. I tried to replace my drill battery pack of 2/3C NiCd cells with higher amp hour Tenurgy AA Nih cells. It workedish. The drill turned(slowly) but the cells were over heating. The AAs could not provide enough amperage to push the motor.
Even at this application (clock) using the same type chemical cell you are going to only get a tenth of the working life compared a D cell of the same chemistry. But it will work in a pinch.

That's true enough.. The AA cell just lasted about 1/5th of the c cell in my case..

Dick Smith electronics, radio shack, jaycar ect all sell AA to C/D adaptors. Dick smith as a matter of fact doesnt even sell rechargable D's anymore, just high capacity AA's that come prepacked in the Clear plastic D shell.

Lol, you should have patented it!

Jaycar huh? might have to get me some of those, and don't get me wrong Siddharth, this is a great idea, i'd just rather have reusable AA to C/D converters rather than making them every single time

Thanks....
Yes I know, making them every single time is not feasible...But if you need them once in a while (as with the clocks), this can work well....

you know, im pretty sure battery chargers charge based on cell voltage and stop when the voltage stops rising, im pretty sure with rechargeable batteries they would work with your method, as you can safely charge them either way, plus the fact the ones i saw at dick smiths were unremoveable, the plastic was on there permanently so theyd hve to be charged in a C/D charger

" im pretty sure battery chargers charge based on cell voltage and stop when the voltage stops rising, im pretty sure with rechargeable batteries they would work with your method,"

You seem to be correct there...

http://www.ebay.com.au/sch/i.html?_sacat=0&_from=R40&_nkw=aa%20to%20c%20adaptor&_sop=15

Literally $1ea on ebay, there are probs listings for like 4-6 which cost even less per adaptor.
Beleive it or not there are even AAA to AA adaptors

Voa!!...I didn't know that!!!..... :O ....I just made it instinctively....and then in mid way, felt, 'I should share that on instructables!' ... nd so I did!!! :D

Thanks for stopping by and commenting... :)

sir..........I bought a digital multi meter , it has all measuring units.........as....AC , DC voltmeter, Resistance meter, its.........but I did not find capacitance meter ........because I have made some homemade capacitors........but I don't know what has capacity those...........! what should I do to know capacity of those..........................................!
