For skillful hands - a self-made battery. For skillful hands - homemade battery Powerful battery with your own hands

In this article, a homemade master will hold us in all stages of the battery assembly, from the choice of material to the final assembly. Radio-controlled toys, laptop batteries, medical devices, electric bikes and even electric vehicles use batteries based on which the battery is 18650.

Battery 18650 (18 * 65 mm) is the size of a lithium-ion battery. For comparison, normal AA format batteries have a size of 14 * 50 mm. Specifically, the author was made by this assembly to replace the lead-acid batteries in the self-made earlings made earlier.

Some tools can be replaced with more affordable.

Step One: Choosing batteries
First of all, you need to choose the right batteries. The market presents different batteries from $ 1 to $ 10. According to the author, the best batteries of companies Panasonic, Samsung, Sanyo and LG. For the price they are more expensive than others, but have proven themselves with good quality and characteristics.
The author does not advise to buy batteries with the names of Ultrafire, Surefire and TrustFire. These are batteries that have not passed quality control at the factory and were purchased at a barn price and are repaid under the new name. As a rule, there are no declared containers in such batteries and there is a risk of fire during charge-discharge.
For his self-made master used Panasonic batteries with a capacity of 3400 mAh.

Step Two: Selection of nickel strip
For connecting the battery needs nickel strips. Two products are presented on the market: nickel-plated metal and nickel stripes. The author advises to use nickel stripes. They are more expensive, but have low resistance and mean less heat, which affects battery life.

Step Three: Spot welding or soldering
There are two ways to have a battery and dot welding. Best selection spot welding. With point welding, the battery does not overheat. But the apparatus for welding (such as the author) is approach. 12 tr. In a foreign online store and approx. 20 tr. In the Russian online store. The author himself uses welding, but has prepared several recommendations for soldering.
When soldering minimize the contact of the soldering iron with the battery. It is better to use a powerful soldering iron (from 80 W) and quickly evaporate than to warm up the place of the solder.

Step Four: Battery Check
Before connecting batteries, it is necessary to check each of them separately. The battery voltage should be approximately the same. In new quality batteries, the voltage is 3.5 V - 3.7 V. Such batteries can be connected, but it is better to equalize the voltage using the charger. U b \\ in batteries the difference in voltages will be even more.

Step Fifth: Battery Calculation
For the project, the wizer needs a battery with a voltage of 11.1 V and a capacity of 17,000 mAh.
Battery capacity 18650 is 3400 mAh. With a parallel compound of five batteries, we obtain a container of 17000 mAh. Denote such a compound p, in this case 5p

One battery has a voltage of 3.7 V. What would get 11.1 in need to connect three batteries sequentially. Designation S, in this case 3s.

So, for obtaining the desired parameters, three sections are needed, each of the five parallel connected batteries, connect sequentially. 3S5P package.

Step Six: Battery Assembly
To assemble the battery, the master uses special plastic cells. Plastic cells have a number of benefits before connecting them, for example, with a glue gun.
1. Lightly assembly of any number.
2. Battery remains space for ventilation.
3.Vibro and shock strength.

Collects two cells 3 * 5. Sets, in the cell, the first 5s battery pack plus to the top, the next five minus up and the last five batteries are again plus up (see photo).

From above sets the second cell.

Step seventh: welding
Cuts four nickel strips for a parallel compound, with a reserve of 10 mm. Slises ten strips for a serial connection.

Puts a long strip on + contacts first (when turned over, it will remain the first) parallel cell 5p. Welds the strip. Welds the strips with one end to the K + third cell to another to - the second. Welds a long strip to + third cell (on top of the plates). Turns over the block. Welds the plates on the reverse side considering that now in parallel we connect the third, and in parallel and consistently the first and second sections (considering that it was turned over).

Step Eighth: BMS (Battery Management System)
First you will understand a little what BMS is.
BMS (Battery Management System) is an electronic board that is placed on a battery in order to control the process of its charge / discharge, monitoring the state of the battery and its elements, temperature control, the number of charge / discharge cycles, the protection of the composite battery. The control and balancing system provides individual voltage control and resistance of each battery element, distributes currents between the component of the battery during the charging process, controls the discharge current, determines the loss of the container from the imbalance, ensures a safe connection / disconnection.

Based on the obtained data of BMS performs the charge charge balancing, protects the battery from short circuit, overcurrent, overcharge, overload (high and excessively low voltage of each cell), overheating and supercooling. BMS functionality allows not only to improve the operation mode of battery batteries, but also to maximize their service life.

An important parameters of the board are the number of cells in a row, in this case 3S, and the maximum bit current, in this case, 25 A. For this project, the master used fee with the following parameters:
Model: HX-3S-FL25A-A
Overvoltage range: 4.25 ~ 4.35 V ± 0.05 V
The range of discharge voltage: 2.3 ~ 3.0 V ± 0.05 V
Maximum operating current: 0 ~ 25 A
Operating temperature: -40 ℃ ~ + 50 ℃
Soldes a fee to the ends of the battery according to the scheme.

As it is often there are situations when in the campaign, in the country or somewhere else, we need to recharge the phone, or it is a bit lit. Most often in the campaign when you need save batteries, you need to call or something else to do. So, let's let's do a battery From what we have at hand!

1. Battery of salt mortar

For the manufacture of a galvanic element, we will need:
1) a large vessel (bucket, you can even a holey, or something like that, you can even polyethylene packages)
2) zinc and copper plate. If there are no plates, then you can use and simply zinc and copper wire, but the plates have a larger area, and give a larger current.
3) Earth. Yes, you can take and just accumulate the earth.
4) Salt solution. There are no accurate recommendations. On the water bucket well, half a pack of salt is enough.

Everything is simple - fall asleep the earth, the electrodes, water, and at the ends of the electrodes you will see the voltage, about 0.5-1V. Of course a little, but what prevents you from doing the battery of such elements? To charge the mobile phone quite enough. I poured, flooded and go to do our own business!

A good option of the self-made element is air-aluminum.
To do this, take an aluminum cathode aluminum foil, the napkin to impregnate with salt (or sea water), I also tried to take an acidic flux, as an anode-hill coal powder, I took a toner from the laser printer's cards. The voltage is 0.5-1.0V at a current of 10m

2. Battery from fruits and vegetables

To make the galvanic element, we need: two electrodes, oxidizer, reducing agent and electrolyte.

Take three plates: copper, iron and magnesium - they will serve as electrodes. To measure the voltage, we need a voltmeter, for these purposes a digital (or analog) tester is quite suitable. And as a "glass" with electrolyte, we use big and beautiful ... orange. Fruit and vegetable juice contains dissolved electrolytes - salts and organic acids. Their concentration is not very high, but it is quite suitable for us.

So, we will put the orange on the table and stuck in it three of our electrodes (copper, iron and magnesium). To each of the electrodes, you first click on the wiring (it is convenient to use "crocodiles" for this). Now join the tester contacts to the copper and iron electrode. The device will show the voltage of about 0.4-0.5 V. Disconnect the contact from the iron electrode and connect it to the magnesium. Between copper and magnesium electrodes there will be a potential difference around 1.4-1.5 V - approximately like a "finger" battery. Finally, the galvanic element of iron-magnesium will give a voltage around 0.8-0.9 V. If you change the contacts in places, the instrument's readings will change the sign ("+" to "-" or vice versa). In other words, the current will flow through a voltmeter in the opposite direction.

Instead of orange, you can use grapefruit, apple, lemon, bulb, potatoes and many other fruits and vegetables. It is curious that the batteries of orange, apple, grapefruit and the bulbs gave rather close voltage values \u200b\u200b- the difference did not exceed 0.1 V. The reducing agent in our case serves iron or magnesium, the oxidizer is hydrogen ions and oxygen (which are contained in the juice). Note that the iron in the galvanic element of copper iron is negatively charged, and in the iron-magnesium element is positive. If you do not have magnesium, the experiment can be carried out with two electrodes - copper and iron. Instead of iron, you can take a zinc or a piece of galvanized tin. The zinc electrode should give a greater difference in copper potentials and less with magnesium.

In the case of citrus, the experiment looks especially beautiful if cutting the fruit across, so that the "lobes" can be seen and insert the electrodes in them (usually the lemon is cut). If the fruit is cut along, it will look not so impressive.

The figures should not be perceived as absolute. The voltage of our battery depends on the concentration of hydrogen ions (as well as other ions) in the juice of fruits and vegetables, the diffusion rate of oxygen, the state of the electrodes and other factors. The voltage of the battery you made can differ significantly from what was observed in this experiment. You can connect several fruit batteries sequentially - this will increase the voltage in proportion to the amount of fruit taken.

For the battery from potatoes, the same materials are suitable, but it gives less voltage about it is recommended to add a little salt inside the potatoes, the effect will be much more.

3. Coffee Battery (Nespresso Battery)

In an attempt to show the world, the importance of collecting and recycling valuable aluminum materials, Mischer designers "Traxler from Vienna has developed batteries from 700 used aluminum jackets and coffee grounds for nutrition of quartz watches. The developed design was called" Nespresso Battery ", the installation is made of old aluminum jars, coffee grounds , Strips of copper and salt water.

In the photo below:
- watch as test device
- Sol
- ground coffee
- Wire
- Copper plates
- Aluminum plates
- Glass
- Plastic bottle separator

To the glass put the copper plate (textolite, coin, thick wire) and aluminum cutting (from beer cans). In order for copper with aluminum to contact, we put the separator from any dielectric (plastic from the bottle, coffee thick) between them), while it should not interfere with the free fluid flow. Connect the wires to the plates, one to the copper and one to aluminum. Now we take water and add several spoons of salt there, we mix them until the salt dissolved. We pour this solution into a glass. All battery done.

Coffee thickness is clean here for entourage, and so that you can give a beautiful name. And so its function can be used to separate the conductors, it is possible to abandon the coffee grounds at all.

4. Baghdad battery (Parthian battery)

A small partfyan vessel was found in Luzhut-Slava, in the vicinity of modern Baghdad (now Iraq), who was once part of the Western Territories of Big Iran. In June 1936, near Baghdad, a new railway was laid - and the workers discovered the ancient burial. In the process of subsequent excavations, it turned out that it belongs to the Parthian period (approx. 250 BC. - 250 G.U.).

One of the finds was a clay vessel with a "tube" from asphalt. Through the "tube" passed the iron rod. Inside the vessel, the rod was lowered into a copper cylinder.

For the first time, this vessel was described by the German archaeologist Wilhelm König in 1938 - he considered it very similar to the electric battery, and published an article on this topic in 1940.

By a similar principle, you can collect your battery. We take a "vessel", which can be made of: clay, plasticine, bottles, cans, glasses, insert the copper plate twisted into the cylinder into it, insert a nickel-plated nail into this cylinder. These plates and nail are electrodes, they must look out a little from the bank. To secure them in the "vessel" housing, you can use: epoxy glue, plasticine, putty for windows, etc.

Now it is necessary to make electrolyte. It can be alkaline or acidic. For a lump, you need to make a concentrated solution from: water + salt or water + soda. For acid, diluted acetic, oxalic acid in water or can be used citrus juice.

Pour the electrolyte inside the jars and carefully clog the "vessel". All Baghdad Battery is ready.

When filling such an electrolyte model, it can produce voltage. In general, depending on the type of electrolyte, the voltage given by the "battery" varies from 0.5 to 2 volts.

Unfortunately, in connection with the destruction of many Iranian literary sources and libraries during enemy invasions to the territory of Iran over the centuries, no written reports have been preserved about what such vessels served. Everything known to us about them today is only guesses.

5. Solar battery

After reading in the limitless expanses of the Internet about homemade sunny elements, I decided to spend my "experiments" in this area. I will tell you about the easiest way to make solar batteries with your own hands.

For a start, I decided to decide on the element base. For the solar cell, we need P-N transitions. They are in diodes and transistors. It was decided to choose silicon transistors KT801. They were produced in the metal case and therefore they can be opened not to spoil the crystal. It is enough to press the passage on the lid and it breaks down.

Now we will deal in the parameters. With middle daylight, each of our transistor produces 0.53V (base - plus, and the collector and the emitter - minuses). And then there is one nuance. Transistors of 1972 release has a large white crystal, and give about 1.1m. Transistors from 1973 to 1980. The release has a large crystal with a green coating, and give up about 0.9m. Transistors produced later have small crystals and provide only 0.13mA.

For the experiment, I used the battery of two parallel chains of 4 transistors. Under the load, it squeezed about 1.8V, 2-2.5m. These are rather modest parameters, but as they say "on free". You can choose such a battery Chinese wristwatches, or charge the battery and feed the LED, bug, etc.

For convenience of attachment and measurements, you can fix transistors on the printed circuit board as in the figure below. My device is made by mounted installation, as it accelerates the assembly.

6. MINEST ENERGY BATTERY

It seems to be the design of the standard, zinc-copper contacts and salted water, but the design of the battery itself is interesting.

We need:

Tray for ice
- copper / copper alloy coins
- Coins of nickel / aluminum bronze / zinc
- Clip
- Sol
- Water
- LED (for verification)

To get the battery, it is necessary to connect coins to the electrodes and pour them with an electrolyte. In each cell of the tray, it is necessary to place two coins from different alloys, such as copper and nickel. Next, connect successively all cells using a clip. Climbing to one side of the wall of the copper coin, and with the other nickel fixes their clips. After that, in each tray it is necessary to pour electrolyte: salt + water. Pay attention to the ends of the tray, since the cells go into two rows, on the one hand we need to connect them, and on the other it should remain without a connection.

Now check the performance of the battery with a diode or multimeter, for this we closure to them two not connected cells.

One cell produces electricity with a voltage of 0.5 V, and connected to one battery - 2 V and 110 mA. This is desirable one electrolyte on all cells, and not heterogeneous.

Features:

1. The cell must be completely filled with electrolyte, but the contact should only be with a coin, and not a clip.
2. One of the pairs of cells should not be closed with each other.
3. Zinc coins are used as positive electrodes, and copper are negative.
4. Coins must be from different metals / alloys (copper and nickel), it is also desirable that the same impurities in alloys.

7. Homemade battery

Now we will produce a fairly simple device, or rather the power supply is a homemade voltage battery. As is known, two different metal immersed in the electrolyte solution are capable of accumulating electric current. As an electrode, it was decided to use copper and aluminum foil (in my opinion they are the most accessible).

In addition to the foil, we will need a sheet of paper, transparent tape and the vessel itself in which we will place the battery bank (very convenient to use a glass vessel from under naphtizin or valerian tablets).

We look at the photo.

Foils are almost the same size, only aluminum foil is slightly longer, there are no reasons for this, it's easier for the copper foil, it is easier to solder than on the aluminum and the wire to foil is not soldered, it is simply rolled into it with the help of pliers.

Next, both foils were wrapped in a sheet of paper. Not allowed to touch the metals to each other, a sheet of paper between them is a fence. Then the foils must be taken together and wrap in a circle and wrap over thread or transparent tape.

Then the made bundle must be placed in the vessel. After that, we take 50 ml of water and dilute 10 - 20 grams of salt into it. The solution is well mixed and heated until all the salt is melted.

After melting the salt, the solution is poured into the vessel where we have a finished blank for our self-made battery. After filling, we wait a few minutes and measure the voltage on the battery wires.

I forgot to clarify the polarity of the battery, copper foil - plus power, aluminum, respectively minus. Measurements will show the voltage of about 0.5-0.7 volts. But the initial voltage does not mean anything. You need to charge our battery. You can charge from any DC source with a voltage of 2.5-3 volts, charging lasts half an hour. After charging, we measure the voltage again, it increased to 1.3 volts and can reach 1.45 volts. The maximum current of such a homemade battery can reach up to 350 million.

You can make several such batteries and use as a backup power supply. We say for the LED panel or a lantern. To increase the battery power, you can use large size foil, but of course such a self-made battery keep the charge will not be very long (during one week the charge runs out), one more minus - a small service life (no more than 3 months), because oxide auxide is formed on copper During the process, the discharge-discharge aluminum foil begins to give in corrosion and gradually split into small pieces, but I think for experiments it is worth trying to assemble such a simple battery.

8. Dock Adapter Adapter

Having some free time and desire, it is easy to assemble the adapter adapter adapter from undergraduate materials to power various gadgets from an external power source. What I liked in this article is the simplicity of such an adapter. I will describe more than manufacturing technology. I think it will be useful to someone else, especially since nothing is difficult here is absolutely.

I didn't even go anywhere for the material. Just on the table, the old card MTS was lying around. Not in vain I paid a hundred rubles. I remembered, it is suitable for making a model of one battery for a fotika.

Cardboard cutting:

Even trimming remains quite a bit.

Cardboard, which is necessary - hard, thickness somewhere 0.25 mm. Made the markup and cut on the seams. The cardboard did not cut through, and approximately a little more than half of the thickness so that it was easier to be bending and glued. For contacts, the copper wire 1.5 square millimeter has bloss. It turned out like this.

So the contacts look from the inside:

Speed \u200b\u200bthe wires and blelled all the seams twice the PVA "Moment of the Stolar". The seams are thin, so I had to smear the tongue with the tongue patiently, on the droplet ... although, if someone does not wait, it is possible to glue my scotch.

Connect to the "Vampire" and work:

Connected, everything worked.

While only one inconvenience was found - the wire. Thick, stretches to the camera and to the "vampire" so conceived to attach the same battery to the camera as in the "Vampire", only with protection. By the way, the batteries with protection here are not necessary, because The camera already has a built-in charge level meter and when the battery discharge it will simply not turn on.

And do not forget to observe the polarity !!!

Dear visitor. If you like a page, share it with friends

You will need

• - glass jar;
• - Lead:
• - clay;
• - sulfuric acid;
• - dimensional chemical dishes;
• - DC source;
• - hydrometer;
• - tester or multimeter;
• - distilled or rainwater;
• - Wires;
• - Light bulb at 2.5-3 V;
• - Locker tools.

Instruction

The battery consists of individual elements. Make one such element. Take a leaf lead with a thickness of 5-6 mm. If you have a lead only in the form of ingots, make it out of shape, dry it and take the plates of the thickness you need, warming the lead on the plate or burner. The plates should have the shoulders on which they will stay at the top edge of the can. In order not to engage in a soldering, when casting the plates can be immediately put in the shape of a piece of sliced \u200b\u200bfrom the insulation of the copper wire, which will continue to be used to connect to the charger or the energy consumer.

Set cast plates on the upper edges of a glass jar. The bank is better rectangular. Plates should not touch each other and bottom banks. To avoid closures, you can put the glass sticks or tubes between the plates. The distance from one plate to the other should not be less than 1 cm.

Such a battery is called acid, therefore it uses a sulfuric acid-based electrolyte. Electrolyte can be purchased ready, but if necessary, nothing prevents it from making it. Concentrated sulfuric acid, which can be found on sale, has a specific weight of 1.08. Divide it as follows. On 3.5 volume of water takes 1 volume of sulfuric acid. Pour water in the chemical dishes, the best distilled. It can be bought in a car shop. Rain filtered water is suitable. Thin-rod with constant stirring in the water add sulfuric acid. Do not forget to ensure that the solution does not sprinkle. Liquids allow cooling (sulfuric acid during dissolution heavily heated). The density of the hydrometer of the boss should be 21-22 ° C.

Prepare. Immediately after pouring the battery it will be necessary. Fill the electrolyte so that it is 1 cm below the top edge of the jar and the top edge of the plates. Immediately proceed to the first charging, which is carried out only by constant current. Mark the polarity of the plates by signs "+" and "-". Fully charged acid battery should show voltage on plates 2.2 V.

All mechanical and chemical works on the battery are finished, but its capacity is still small. To enlarge it, swipe molding. Connect the light bulb to the output wires and allow the battery to fully discharge this load. Check the discharge with a tester or multimeter.

After discharge, charge the battery "on the contrary", that is, changing the wires of the wire going to the charger so that "+" became "-" and vice versa. Rent a battery across the light bulb. It is desirable to do this operation 15-20 times to increase the battery capacity is approximately twice. It is not worth forming it.

Battery It is advisable to supply the lid to protect the electrolyte from contamination. The lid can be made of any dielectric, even from a tree impregnated with paraffin. Battery conclusions It is advisable to appease in the form of terminals or clamps. Be sure to mark their polarity upon completion of the last molding cycle. When operating the acid battery, instead of the evaporated electrolyte, do not plot, add only water to the previous level. If you want to make a battery, connect several such batteries sequentially.

Of course, the battery is easy to buy in any household goods store, electronics or in a hypermarket. However, for the sake of interesting experiments and obtaining knowledge of the "School of Life" yet it is still worth knowing how to make a battery with your own hands. Especially the process of such work is very entertaining and simple.

Lemon Battery: Two options

For the first option you will need:

• actually lemon;
• galvanized nail;
• 2 small segments of copper wire;
• copper coin;
• small light bulb.

The process of work is:

1. Make two nurses on fruit at some distance from each other.
2. In one incision, put a nail, and in the other - a coin.
3. And to the nail, and connect to the coin on a piece of wire. The second ends of this improvised wiring should come into contact with the contacts of the bulb.
4. And all - it will be the light!

The self-made sour fruit battery can be done with:

• one of the same lemon;
• stationery clips;
• light bulbs;
• 2 segments of an isolated copper wire with a diameter of 0.2-0.5 mm and 10 cm long.

The algorithm is the following:

1. Clean 2-3 cm of isolation at the ends of each of the wire.
2. Attach the bare part of one wiring to the clip.
3. Make two outbreaks in Lemon 2-3 cm from each other - on the width of the clips and for the second wiring. Insert these elements into the fruit.
4. Loose wire tips attach to the contact part of the light bulb. If it does not catch up, it means that the chosen lemon is not enough power - consistently connect several fruits among themselves and repeat the experience.

Potato battery

Follow:

• two potatoes;
• three wires with clips;
• two chrome nails;
• two copper nails.

So how to make a battery from the tuber:

1. Give the conditional designation of each of the potatoes - "a" and "b".
2. In the edges of each of the tubers, stuck on a chrome-plated carnation.
3. In the opposite edge - a copper nail. In the body of potatoes, nails should not intersect.
4. Take any device that feeds from the battery, remove it and leave the compartment open.
5. The first wire should connect the copper pin of the tuber "A" with a positive pole in the battery compartment.
6. The second wire connects the chrome-plated pin of potatoes "in" with a negative pole.
7. The last wire connects the chrome nail of the tuber "A" with a copper nail of the tuber "B".
8. As soon as you close all the wires, the potatoes will begin to feed the device with energy.

Potatoes in this experience can be replaced by banana, avocado or any of the citrus.

Foil, Cardboard and Coins Battery

Before making a battery, prepare:

• copper coins;
• vinegar;
• salt;
• cardboard;
• foil;
• scotch;
• two pieces of isolated copper wire.

All is ready? For business:

1. At first, it is necessary to capitalize coins to be capable - for this pour vinegar into a glass container, add salt there and pour money.
2. As soon as the surfaces of the coins were transformed and slaughtered, remove them from the packaging, take one and 8-10 times circuit its outline on the cardboard.
3. Cut cardboard circles along the contour. Then place them in a container with vinegar for a while.
4. Fold the foil several times so that the end is 8-10 layers. Drive on it a coin and also cut round parts by contour.
5. At this stage, start collecting the battery. This is done like this: copper coin, cardboard, foil. In this order, fold all the components you have in the column. The final layer should be only a coin.
6. Remove insulation from the wiring tips.
7. Cut a small scotch strip, stick one tip on it, put an improvised battery on top, the tip of the second wiring on it. Securely secure the design of the adhesive tape.
8. Connect the second wire tips to "+" and "-" devices that need to be used.

Eternal battery

Prepare:

• glass jar;
• silver element - for example a spoon;
• food film;
• copper wire;
• 1 teaspoon of cook soda;
• 4 bubble glycerin;
• 1 teaspoon 6% apple vinegar.

1. Tightly wrap the spoonful of the food film, leaving its top and bottom end slightly bare.
2. Now it is time to wind the spoon over the film with copper wire. Do not forget to leave long ends at the beginning and at the end for contacts. Make space between the turns.
3. And again the film layer, and behind it - the wire is the same method. The layers of the "Wire film" on this improvised coil should be at least seven. Do not tighten the layers of too much - the film should be filled freely.
4. In a glass jar, prepare a solution of glycerin, salt and vinegar.
5. After the salt is dissolved, the coil can immerse into the solution. As soon as the fluid is like, the "eternal" battery will be ready for operation. The term of its service directly depends on the content of silver in the coil element.

Graphite rod: Application

The graphite component of the old batteries is not only the basis for a new energy source, but also an element that can be used for electric welding. This is done by a simple scheme:

1. Sharpen a graphite rod from an old battery at an angle of 30-40 degrees.
2. Clamp type "crocodile" with a tok-conductive handle Connect it to "+" and "-" source of alternating or DC.
3. Connect "0" and "-" to the stripped part.
4. The electrode as burnout must be pulled out periodically.

How to make a battery at home? Required sweater materials, a little enthusiasm and perfection. In exchange you will receive alternative energy sources.

In this video, we will show how to make the battery do it yourself. For its manufacture, we will need a small container with a lid, soda, water, charger.

Will in the jar from vitamin water, we embarked in it 1.5 teaspoons of food soda. Mix the solution well. Clean the welding electrode from the coating. Cut from the electrode two pieces of 7 cm. We drive the ends of these billets. Insert these billets into the holes in the lid and tighten it into the bottle.

The charger is connected to the ends of the battery. We charge the battery 10 minutes and check the work of the self-made battery. The estimated voltage at the output of 1.5-2.5 volts. This nutrition is enough when charging 3 hours for 20 minutes of the luminous LED. In order not to do your battery, do not make it hermetic.

Another way to manufacture a self-made battery

Homemade battery made of primary materials with a minimum of tools. Imagine the situation when there is no need for the right details, more precisely, the minimum is available, but you are in the field when there is no diversity. We will have to experimentally artificially limit yourself with the choice of materials.

Take the absence of copper in the plates of copper wire. Isolation delete with fire. Pruning galvanized iron applied to the same plates. Wiring with insulation for connecting the chain. It is possible to immediately take a conductive wire without isolation. It is also necessary to find a polyethylene bottle, any dielectric is suitable. Conductive liquid solution (hydrochloric or acidic, alkaline). Disposable cups.

To begin with, the wire annealed wire to increase the area twisted into the cylinder. From the galvanized, we cut the same plates by the template and weching into the cylinders (the corner bend to clamp the contact wire in it).

From the plastic bottle, we cut the gasket material that will be located between copper and galvania. We collect battery elements, one end of the wire is fixed on the thread, the other on the zinc and two single. One with copper - plus and zinc - minus.

We collect the battery in the serial chain. To begin with, try to pour a solution saturated with salt. In the field, any saline solution, urine and other suitable. 7.74 volts voltage. We will replace the saline solution to the acid, in the experiment used vinegar table. In the field conditions, the blackess wine is suitable for our infusion from sorrel, Morse from cranberries and more. Voltage 8.05 volts.

We can replace an alkaline solution, the soda food in nature can be triggered to replace the ash placed in water (cloth), but must be experimenting for verification. Voltage 9.65 volts.

So let's summarize: average of 10 elements we get 8 volts, one cup is 1.25 volts. To reduce the voltage to charge the phone (5.5 volts), remove the two cups, the procedure takes 20 seconds. Or increase to 4.5 volts by adding 5 cups. So you can make a battery when there is no possibility to buy it, with your own hands.
