Why it is not recommended to throw batteries in regular trash

Even a small battery contains lead, mercury, alkali, nickel and other dangerous metals. As long as these elements are under a protective shell, there is no threat to either people or the environment.

Danger of batteries for humans and the environment

A used battery that ends up in a landfill decomposes when exposed to an aggressive environment. All harmful substances that were previously under the shell enter the water, air, and soil.

Harmful components begin to travel through nature. They easily get into the water and infect fish, which can later end up on the table. Even high-quality heat treatment will not help get rid of harmful substances.

Attention! One small battery can pollute an area with a radius of up to 20 square meters. m.

Types of batteries

Modern models of household floor scales usually have a display that displays all operating information. Some models are supplemented with options that will help you start leading a healthy lifestyle and get rid of extra pounds.

In household floor scales, as a rule, three types of batteries are installed:

Foundry CR 2032/2430. They are usually called "tablets" or "coins". They have a round flat shape, element diameter is 20 or 24.5 mm, operating voltage is three volts. They cannot be recharged, only replaced completely. Buying them won't be difficult.

Some floor scale models come with batteries included.

Battery disposal rules

Self-disposal is prohibited. This can have a detrimental effect on your health. Some chemists disassemble the battery, trying to dispose of it according to the rules. Thus, they obtain zinc from the cups, after which they melt it down. Subsequently, the zinc is used to produce hydrogen. Coal hearts are used as electrolysis. In this way, materials are reused.

Products marked with this sign must not be thrown into regular trash!!!

Ordinary citizens should recycle old batteries according to the following algorithm :

1. The element is placed in a bag, a plastic bottle, or any container with a tightly closed lid.
2. Once the container is full, which usually takes up to 10 years, it is taken to a collection point.
3. Place in a special bin.

In a factory environment, processing is carried out in a different way:

1. Initially, workers manually sort batteries by type.
2. The used products are sent to the crushing plant.
3. The processed raw materials are sent under a magnetic tape, where large body elements are separated.
4. The surviving parts are sent for re-crushing in order to obtain all the iron.
5. The electrolyte contained in the mass must be neutralized.
6. Raw materials are divided into components and packaged in containers.

This completes the processing.

How does the replacement take place?

To bring bathroom scales back to life, do not use batteries removed from other household appliances. A partially used element does not have a stable voltage, so the data on the device may be displayed with errors, or the equipment will not even turn on.

Before replacing the battery yourself, you need to turn the scale upside down. There is a special compartment at the bottom that can be closed in two ways:

1. The lid slides into special grooves.
2. The plate is held on a special screw that needs to be unscrewed with a screwdriver.

Battery compartment

When the compartment is open, you need to remove the used batteries. If they fit tightly, you can use nail scissors or a nail file. You need to insert a new battery in place of the removed one. In this process, it is important to respect the poles - plus and minus. Hints are always available on the device body.

Once the power is properly installed, the compartment must be closed.

How do you know where the “+” is on the battery and where the “-” is?

First we determine visually. Where “+” is marked, there is, accordingly, “plus” (with a high probability).

If it is not possible to determine this, then usually the smaller end is either hidden deeper, or is a “male” - “plus” type connector, and the one that goes to the body or “female” type is a minus.

If you have a tester at hand, then there are no problems in determining the battery poles. We connect the tester wires to the battery in DC measurement mode. The tester wires are usually marked - “plus” - red, “minus” (ground) - black. If the arrow of the device goes to the positive, then where the red wire of the tester is - there is a positive for the battery, otherwise - there is a negative.

You can determine the poles using a piece of raw potato and copper wires. We assemble the following unit:

Where it turns green, there is a “plus”.

Another way is to immerse the wires connected to the battery in salted water. Where gas bubbles go, there is a “minus”.

Container for used batteries

Many organizations, aware of the harm that can be caused to the environment and humanity, make special containers for batteries that have reached the end of their shelf life. A wide range of finished products are on sale.

What are they: types and advantages

Manufacturers offer for sale several options for containers for storing batteries, differing in internal volume. Such products are used at home, in public institutions, and in office premises. When choosing, it is recommended to take into account the number of visitors to the establishment and residents.

There are three types of containers:

1. Small volume. Designed for 50 people, includes 1 box for 15 kg. Approximate cost: 8,500 rubles.
2. Medium volume. There are 3 boxes of 45 kg, intended for 500 people. Approximate cost: 25,000 rubles.
3. Large volume. Includes 5 boxes, total weight capacity 75 kg. Approximate price – 35,000 rubles.

If the container is chosen correctly, it lasts for 1 year.

Battery containers in Europe

In Russia, many people consider it right to throw away the battery after use and safely forget about it. The collection system began to emerge relatively recently. Few manufacturers specialize in the manufacture of collection containers.

In Europe, things are different. A collection box is installed in front of each store that sells batteries. There are no problems associated with proper disposal. Anyone who brings a battery for recycling receives a discount on the purchase of a new one.

These boxes are painted bright green. There are yellow variations. The shape of such a container imitates a AA battery.

Variety of models

Modern manufacturers are ready to offer several types of containers for collecting batteries. Each model differs not only in appearance, but also in size. When choosing the most suitable option, you must be guided by the attendance of a particular organization, as well as the average consumption of autonomous batteries.

All containers for used batteries that exist today can be divided into three categories:

1. Compact. The containers are designed for 50 people, since the box can hold a maximum of 15-16 kg of products.
2. Medium containers. These are three spacious boxes for 46 kg.
3. The largest containers. The set consists of five boxes weighing up to 78 kg. It is worth noting that products from this category are the most expensive.

If the choice of the finished box was made correctly, then it should last for at least a year.

Such designs are often accompanied by bright posters, as well as interesting drawings that attract the attention of others.

DIY container for collecting batteries

If it is not possible to purchase a ready-made battery box, you can easily make one yourself. There is nothing complicated about it. A metal barrel intended for storing oil or petroleum products is an excellent base. Volume from 200 to 400 l, a drain hole located on the lid is required. The cost of an empty container is 300-500 rubles.

The algorithm of actions is as follows:

1. Using a marker, mark the door on the side of the container. Size 45 by 45 cm. If necessary, choose other sizes based on the dimensions of the barrel.
2. Using a hacksaw or grinder, prepare the side cuts. After this, the door hinges and lock are installed. Only after this can you finish cutting out the future door on the other two sides.
3. Since the door can be scratched during use, the edges are carefully filed.
4. If necessary, the container can be painted in any shade, a drawing or inscription can be applied. Using stencils, the inscription “for batteries” is applied.
5. Since there will not be much waste material at first, the container can be blown away by strong gusts of wind. To prevent this, reinforcement will be required - a bag of sand, gravel, or pebbles is added to the lower part.

Inserting new batteries: step-by-step instructions

In order to insert the batteries, we need to use the following step-by-step instructions:

1. Decide on the device for which they are intended.
2. Decide on the type and shape of batteries you need.

Data collection, purchase of new batteries

In order to power the consumer device with the required amount of energy, we find out what type of batteries it uses.

Such information can be read on the box, packaging, instructions, instruction manual or the product itself (in the area of ​​the battery case).

For example, it could be a AA cylindrical battery (one or 2 pieces).

These are the ones you have to buy.

Selecting a battery by type and price

When contacting the seller, you should make a choice between salt, alkaline, and rechargeable batteries.

We have written about this more than once on the pages of our website battery.rf, therefore, problems should not arise.

If you can choose between cheap and expensive batteries, it is recommended to take elements that are more expensive or higher than average prices.

Ideally (for the energy consumption of frequently used and powerful devices, such as a camera or player), it is better to buy batteries. If we talk about a low-power calculator or watch, disposable batteries will be enough.

Consultation + marking + head

When buying new batteries, do not hesitate to ask the seller for advice, ask about expiration dates and power. Also, pay attention to the labeling of the batteries.

The first letter indicates the chemical composition:

The second letter in the marking is the shape of the current element:

For example, 6F is 6 coin batteries wrapped in a common housing. What is being done to increase the total voltage.

The numbers at the end of the marking are the radius of the battery.

Connecting batteries

When new and suitable batteries have been purchased, we have to carefully examine the device for inserting them. It is not difficult to find the desired compartment by visually inspecting the consumer device and finding the required cover.

More often, such battery compartments are hidden on the back or bottom side of a current-consuming device (watch, calculator, flashlight, etc.).

At the same time, here you can also find a visual and clear diagram of the placement of batteries in the compartments.

Plus and minus

To determine the polarity of the battery and its positioning in the compartment, carefully examine the case and terminals. There is almost always a spring on the negative side of the contact in the compartments.

We see a spring - this is the “-” side (the flat side of the battery).

The convex end of cylindrical batteries is their “+”.

Moreover, the polarity must be indicated on the battery case or label.

Note: On flat, disc, button and pill batteries, the plus is located on the flat side! And the convex end here is a minus!

We follow the scheme

Following the diagram, instructions, and instruction manual, insert new batteries into the compartments and maintain the polarity.

Next, the device can be turned on and tested.

For example, users often confuse polarities, hastily replacing batteries in violation of their operating instructions.

To power powerful photographic equipment, the energy of salt and cheap batteries may not be enough.

In this case, the device will also not work.

Battery collection points: where to return them

Used batteries pose a serious threat to the environment and the population itself. Used products can be disposed of in special containers located in large stores and retail chains. Often there is a campaign “donate a battery - save the planet” . Participation in the promotion allows you to receive a discount on the purchase of similar products.

(Look at the Yandex maps of your city where you can donate batteries https://yandex.ru/maps/?source=serp_navig&from=tabbar&text=batteries%20%20reception points)

Factories

The very first plant that began recycling old batteries in Russia is located in the Chelyabinsk region. Collecting used batteries brings a small, but stable income. In addition, such activities are useful for the country.

Disposal is carried out on a paid basis. For 1 kg of raw materials there is a fixed fee of 110 rubles (the price is approximate, due to the unstable economy it may change). Up to 1000 tons of batteries are recycled annually.

A battery recycling plant was opened in Novosibirsk

Retail networks

You can often take used batteries to retail chains where there are special collection containers. As a rule, these include establishments operating in places with large crowds of people. These could be shops, markets, cafes.

The most popular reception points in Russia:

1. Media Market.
2. Auchan.
3. El Dorado.
4. M Video.
5. Ikea.

The devices are installed next to the main entrance or indoors. To attract attention, it is made in the form of a giant battery.

Battery selection

At first glance, choosing a AA battery that can be charged using a charger may present some difficulties, because outwardly such an element is no different from a disposable one. However, when purchasing, it is not necessary to resort to the help of sales consultants; it is enough to understand the labels on the product.

For example, the voltage value of a conventional battery will be 1.6 V. For a battery, this parameter is lower and is 1.2 V.

A little knowledge of English will also not hurt in such a situation. The inscription rechargeable on the element in translation means “rechargeable,” which speaks for itself. And vice versa - the phrase do not recharge will tell the potential consumer that the battery is not subject to alternate charging.

Another difference is the manufacturer’s indication of the battery capacity, which is expressed in mAh (milliampere hour). You will not find such a parameter on a regular one-time element.

Rechargeable AA batteries, which receive “new life” from a charger, are divided according to the type of material that is their basis.

Nickel-cadmium battery

They are the cheapest compared to other varieties. Despite their low cost, such rechargeable batteries are not without advantages, the main one of which is the ability to retain a charge at subzero temperatures. There are several disadvantages - the inability to accept a charge until completely discharged and its loss even without using the element in the device.

Nickel metal hydride

Such elements have the ability to store their charge for a long time, but for this opportunity the owner pays with considerable dimensions and the cost of such a battery.

Lithium-ion

One of the most modern batteries, the main advantage of which is the absence of a “memory effect”, as is the case with Ni-Cd-based cells, and the ability to retain a charge for a long time. The main disadvantage is the high cost in relation to other varieties and the effect of rapid self-discharge when operating at subzero temperatures.

Occasionally, you can see the inscription LSD on some batteries. The English abbreviation stands for low self-discharge, which translates as “low self-discharge”.
