What can be made from batteries: new and old

It is difficult to imagine the life of a modern person without a variety of devices. Many of them require small batteries - batteries. But as experience shows, we know little about all their capabilities. For example, you can make several original things out of ordinary batteries, and when they fail, you can properly dispose of them.

What can be made from a battery?

If you mobilize all your imagination, then even from familiar devices you can make something unusual.

Battery magnet

To make your own magnet, you will need:

1. Copper wire. It is advisable to take a varnished one. This way the device will not short out during operation.
2. New battery.
3. A small carnation.

Carefully wrap the copper wire around the nail. The turns should be located as close to each other as possible. Connect the two free ends to the battery.

Reference. The more turns of wire you make, the less the device will heat up.

Stun gun

Prepare the following materials:

1. Krona type battery.
2. Transformer. It can be “borrowed” from a charger, modem or other equipment that has a 9 V power supply.
3. Ebonite rod 40 cm long.
4. Steel wire 5 cm long.
5. Electrical tape.

Assembly steps:

1. Attach 2 pieces of wire to one end of the ebonite rod.
2. Connect both pieces of wire to the transformer.
3. Connect the battery to the transformer contact.
4. Place a switch at the other end of the rod. When you press it, an electric arc should appear.

Reference. It is worth keeping in mind that the current strength in a homemade device will not be enough to “knock out” a person. A stun gun can only be used as a means of intimidation.

Miniature hand warmer

As you know, there are two types of people. Some are freezing even in the middle of hot July, and some are ready to show off their bare hands even in the bitter cold. If you belong to the first group, then you simply need a mobile hand warmer. Take two batteries and wrap them in foil, carefully pressing them against the positive contacts. Press the “plus” and you will immediately feel how your hands warm up.

AA from AAA

Did you purchase the wrong batteries? It's OK. Using small pieces of foil you can turn AAA into AA. Insert the batteries into the device and secure them with foil.

Battery lighter

To make a lighter, prepare the following materials:

1. “Krona” for 9 V, a new one and one failed one.
2. Thin wire. If possible, replace it with nichrome.
3. Cable.
4. Glue.
5. Soldering iron and all necessary soldering equipment.
6. Two bolts with nuts.
7. Button.

After all the materials are prepared, you can start assembling:

1. Apply a thin bead of clear glue to one side of the battery and glue one of the bolts in place.
2. Repeat the manipulation on the other side of the Crown.
3. Take the Krona that has become unusable, disassemble it and take out the plate with the positive contacts.
4. Use a soldering iron to connect one of the contacts to the bolt.
5. Take a nail and wrap the wire around it. There should be a spring.
6. Secure it to the bolts with nuts.
7. Connect the second wire first to the button, and then to the “Crown”.

Stylus

The negative side of any battery is a great stylus for the touch screen

Fire from batteries

This is one of the most popular life hacks. To do this you will need a small piece of paper-based foil. For example, you can take a package of chewing gum. Attach it to the contacts of the current source and bring it to the object that needs to be set on fire.

Motor

Take some thin copper wire, a power source, 3 small round magnets, a couple of paper clips and some reinforced tape. Next, proceed to assembling the motor:

1. Wind the wire around the battery. You should make at least seven turns.
2. Remove the resulting “spring”. Bend the ends of the wire around it. Sand them thoroughly.
3. Straighten the paper clips. Use tape to secure one paper clip to the end of the battery. Repeat the manipulation on the other side, taking a second paper clip.
4. Bend them at a right angle and secure the wire spring.
5. To set the motor in motion, place a small magnet on the battery.

What can be done from old batteries

Don't rush and throw away broken batteries - you can give them a second life.

Even a dead battery can be made to work. To do this, slightly deform its body. This should be done carefully so as not to break the seal of the device.

You can also make an original lamp. You will need:

• old but not damaged power source;
• miniature light bulb;
• copper wire;
• stationery tape;
• paper, polymer clay.

Manufacturing stages:

1. Divide the copper wire into two equal halves.
2. Using tape, attach one part to the negative terminal.
3. Wind the other half of the wire around the light bulb base. Fix its free end to the positive contact of the battery.
4. To turn on the light bulb, close the circuit.

Battery disposal rules

It is highly recommended not to dispose of batteries that have become unusable as other waste. This is explained by the fact that the device contains various substances that cause significant harm to the environment, for example:

• electrolytes;
• acetylene black or graphite;
• steel capsule;
• plastic and paper components;
• manganese dioxide.

The body of the device begins to rust over time, which means it loses its original tightness. Because of this, toxic substances enter first the soil and then into groundwater. Then underground water flows carry them into large bodies of water.

Therefore, a system for recycling batteries has been developed in all countries. Products that have become unusable are widely used in metallurgy, in the manufacture of fertilizers or pencils.

Some large hypermarkets, for example IKEA, accept old power sources. To do this, they placed special bright yellow containers. You can also donate batteries to organized collection points.

If you want to make something original or extend the life of batteries, remember that your experiments must be safe.Do not involve small children in this process or use damaged batteries.
