This project is very environmentally beneficial, as it takes a dead battery and turns them into a new one, preventing the creation of electronic waste. The possibilities are endless on this concept (stronger batteries, tiny batteries) and just think of what it would be like if everyone on this planet was able to recycle old batteries.Just we need the electronic waste to be turned into a new battery .Needed for just about every electronic project, electronics revolve around them. But think about it, What happens once they lose their power? You throw them away, just like all 7 billion of us on earth.And this project is all about calculator battery . As our calculator battery gets dead we need to purchase a new one .But that costs some money and also creates waste so here's a fresh instructable which would tell how to make DIY calculator battery.
Step 1: Things Required
For this project we need :-
- Old discarded AA sized battery
- Aluminium foil
- Long - tiny container
- acid (vinegar) ,salt solution or simply tap water
- This we need to make this
These all can be got from scrap except precious water .
Step 2: Dissecting the Cell
Most of the dry cells they consist of a Carbon Rod (what we need) surrounded by moist electrolyte paste.
Cathode (Positive ): Carbon Use the pliers to take out carbon rod from the cell.Once its off, you will see the top of the carbon rod, slowly pull until the carbon rod is out.
Step 3: Cleaning Cathode
After taking it out you should clean it with some sort of cotton clothes to prevent including of some other unwanted chemicals.
Step 4: Container Holes
Take a screwdriver or scissors to make a hole in container cap and then pierce carbon rod through it .Drill a whole the size of the carbon rod so it fits snug. Place the carbon rod into one of the hole leaving about 1/2 an ince sticking out from the top
Step 5: Making Anode
Now you need a piece of aluminium foil that should surround the container from inside but in such that position that the carbon rod should not make contact with it .To do this firstly cut a square piece of foil and then make a rectangular strip of it and then make it roll around the body to cast it in its dimensions and move on to next step.
Step 6: Connecting Wires
The carbon rod is now +
The foil is now - just take two wires and connect them to the two electrodes . Use glue to make it water proof .
Step 7: Filling Electrolyte
Fill the tiny container with a salt water mixture and place the lid back onto the container. You are now done.Mix it fully to make a solution . If desired make it saturated.
Step 8: Final Finishing
Now You Must screw down the cap of container and close it tightly and the two must must be connected to the terminals of the calculator Red wire (usually +ve) to carbon rod and black wire (usually -ve) to aluminium foil and then move on next step.
Step 9: Done!
First of all test the battery on opened calculator if it is working then close the calculator and Do calculations . The first picture is of open calculator and second one of closed . I've edited second picture using the method told in Pure White Background Photography Using Smartphone instructable.Just think of the limitless possibilities you can create with your own batteries. Not only do they work, they also reuse old dead batteries, preventing the creation of electronic waste.
