A charger is a device that charges a battery. How to choose it? Which memory is better? And what does the market offer us? All this is written below.

Types of chargers for car batteries

There are different types Charger for battery. Let's look at 8 options plus a common classification.

Pulse charger for car battery

A pulse battery charger charges with high-frequency current. Devices of this type are miniature.

The following variants of pulse memory are distinguished:

1. Manual chargers require human control. You need to manually adjust the current strength, charging time and voltage.
2. Automatic are programmed chargers that independently determine the battery parameters. They are able to automatically regulate the entire charging process.
3. Semi-automatic or semi-automatic are charging systems that perform part of the processes automatically. You will have to control the charging time manually.

Pulse charging of the battery comes in three options:

1. Charging with constant pulse current.
2. Filling with energy using constant voltage.
3. A combination of the two options above.

Sometimes there are situations when you need to start the car right away. A powerful pulse “charger” for the battery makes this the “ BOOST».

Please pay attention to this at the time of purchase. By using BUSTA Charging will occur in 5-10 minutes. This is enough to start the car.

Pre-charger for car battery

It is required when it is impossible to disconnect the battery from the network. The main advantage is that you do not need to remove the battery from the car. Startup after connection is not possible.

Starting device for battery

Allows you to start the engine in a matter of minutes!

The device is compact and easy to use! It is enough to connect the crocodiles of the starting charger to the battery terminals. The required amount of current will be generated and the car will start.

Starting charger for car battery

Allows you to charge the battery and start the car immediately after connecting to the network.

Three types of charger for batteries:

1. Household ones are chargers that are used in the garage. Operate from a 12 volt network. There are 6-volt devices on the market. They are also capable of starting a motorcycle.
2. Professional are devices in contact with a 12-24 volt network.

Such devices are identified by the presence of thick wires.

Transformer charger for car battery

The main key figure here is the transformer. Its disadvantage is its dimensions. The principle of operation is to reduce the voltage according to the principle of a conventional converter. That is, from high to low. Large charging currents take part in charging the battery.

The auto charger for a 12-volt battery is regulated by the program. Smart electronics will do everything according to the correct algorithm and protect the battery from various dangers.

This device charges and cleans the battery from lead sulfate. I call this phenomenon desulfation. The device is protected against incorrect connection of wires and short circuit brands Thanks to the built-in controller, the optimal charging mode is selected.

Automatic chargers have 4 types of operation:

1. Battery charging mode. Its stages: The first step is to charge up to 14.6 volts with a stable current of 0.1 s (C is the battery capacity in Ah). Then comes charging with a voltage of 14.6 volts. This happens until the current drops to 0.02 C. Then it maintains a stable voltage of 13.8 volts until it reaches 0.01. At the end, the battery is charged. If the voltage drops to 12.7 V, the above circuit is repeated.
2. Desulfation. Operating cycle: 5 seconds of charging with a current of 0.1 C. This is followed by a 10-second discharge with a current of 0.01. This occurs until the battery voltage reaches 14.6 volts. Then normal charging occurs.
3. Battery Test. This mode makes it possible to find out how much the power source is discharged. After a current load of 0.01 C, the voltage at the contacts is measured for 15 seconds.
4. Control-training cycle mode. The battery discharges to a voltage of 10.8 volts. Then the specified mode is activated. Having received data on the charging current and time, the system determines the battery capacity. The data will be displayed on the device display.

There are usually two types of automatic chargers.

5-stage memory

Here's what it does:

• Charges the battery up to 80 percent!
• Perform full charging with reduced current
• Preventatively keeps the charge at 95-100%
• Eliminates sulfation on plates
• They do battery diagnostics.

8-stage automatic charger

The device has an eight-step charging cycle.

Here's what his job is:

1. Due to charge-discharge, the plates are cleaned.
2. The power supply is tested for functionality.
3. The battery is charged to 80% capacity.
4. Charging occurs smoothly up to one hundred percent, with minimal current.
5. A check is made to see how well the battery holds a charge.
6. All electrolyte separation is eliminated.
7. maintained at maximum.
8. A preventive charge is carried out up to 95-100 percent!

Second classification of battery charger

Types of settings:

1. Manual - you configure everything yourself.
2. Automatic - everything you need is already configured by a computer program.

According to the car battery charging scale

The car battery charging indicator is as follows:

1. Switches
2. LED
3. Digital

By connection type:

1. Connected from a regular 220 volt network.
2. Connected to the cigarette lighter. This type is the most convenient, as it is small in size and portable.

By charge duration car battery:

1. Slow - perform charging during the day.
2. Fast - charge in 2-3 hours.
3. Air conditioning. Typically, chargers with this speed charge the battery within 1 hour.

New chargers for car batteries

Which charger for a car battery is better?

It's difficult to choose the best. All chargers work great. Short review popular models are presented below.

This type of charger is quite simple. There is nothing fancy about it. There is simply a transformer with switching of the terminals of the secondary or secondary winding. On the case, the 4A/6A toggle switch is responsible for switching. In addition to the transformer, it contains a diode bridge and an ammeter measuring device.

This device is unpretentious. It can be left in a cold, damp garage. It's unlikely to break.

According to the manufacturer, such a power source is designed to work with ninety-amp batteries. But in practice this is 65 amperes maximum!

Do not use the charger to charge gel and AGM batteries. This is due to the fact that at the end of charging the voltage level at the terminals can be about 15 volts. Such voltage can cause damage to these batteries.

Among many others, this charger stands out for its miniature size. It is capable of charging different batteries. Has many charging options. Built-in sulfation mode. Thanks to it you can charge a completely zero power supply!

The peculiarity of the device is the presence of a “power supply”. When the current does not automatically decrease at the outputs, turning off at the end of the charging process, but maintains a certain voltage level at the contacts.

Drivers find a lot of uses for this mode. For example, you can power a carrier with 12 volts or revive seemingly unusable batteries.

Using automatic charging, the driver simply needs to set the ammeter to the highest charging current, determined from the battery capacity.

Elitech UPZ 30/120

The device works with a 12-24 volt battery. The device has two charging options:

1) Normal – allows you to work with a maintenance-free battery;

2) Fast - makes it possible to recharge lead-acid batteries, because it has a high current;

The presence of a special start mode toggle switch disables automatic protection. This allows the device to deliver as much as 120 A to the load. This is normal for a compact charger model.

This charger weighs only 1.5 kg! Delivers current up to 50 A. Allows you to start at a time when the starter needs little current.

To select the charging mode, press the “mode” button. After this, the charger itself will set the necessary parameters. If desired, voltage and current can be displayed on the main display. If there is a malfunction, an error message will appear.

How to check a car battery charger?

In some cases, you might think that the charger is acting up. But it is not always the case. Some chargers are simply not designed to charge empty batteries. Residual stress is required here.

A couple of things to pay attention to:

1. Make sure that the charger is capable of charging not only a medium-sized battery, but also a completely discharged one.
2. Check the fuses if possible.
3. If the charger voltage is below 13 volts or it jumps strongly, this means that it is broken.
4. Connect any 12-volt device, such as a light bulb, to the charger terminals. If it is on, then the charger is working, if not, then it is broken.
5. Check the integrity of the wires and their fastening. If no current flows through the wire, then this is the reason.

You can check your charger using these tips. If you are not good with electronics, then it is best to take the device to a technician at a service center.

How does a car battery charger work?

The process of charging a car battery is as follows. The charger converts the mains voltage of 220 volts into what is needed to charge the batteries. Next, the battery terminals are supplied through wires coming from a powerful charger. constant pressure. It can be pulsating or smooth and exceeds the potential difference between the electrodes.

Due to this, current flows inside the battery in the direction opposite to the discharge. Particles of the oxygen molecule are “squeezed out” of the cadmium and penetrate through the electrolyte layer to their original place. This allows you to restore capacity.

The chemical composition of the plates changes during charge and discharge. An electrolyte is a medium where cations and anions pass through. The speed at which current flows inside the battery affects the rate of restoration of the properties of the plates and the charging speed.

The processes proceed quickly, this causes strong gas release and heating. This can damage valuable plates.

Low charging current prolongs the process of capacity restoration. Frequent use of a slow charge increases plate sulfation and reduces. In this regard, it is necessary to take into account the power of the charger and the load supplied to the battery.

Conditions for charging a car battery

Do not use the charger in a damp place or in an unventilated area. The vapors released during the charging process are harmful to the body.

Cable for car battery chargers

Traditionally, chargers use two cables with a cross-section of at least 1 mm. The wire colors are usually red "+" and black "-". In fact, you can take wires of any color, the main thing is to follow.

For convenience, an alligator clip should be attached to the end of the cable. This will allow the wire to hold securely and touch the battery contacts.

Rules for using chargers

Rules for operating chargers for car batteries:

1. Use the charger away from open flames, burning cigarettes, etc.
2. Protect the charger from moisture and dampness
3. Charge the battery in a ventilated area
4. Only charge whole batteries
5. Do not remove the clips from the power source while charging.

8. No need to shorten or lengthen wires to connect the charger
9. When working with batteries, wear gloves and special glasses.
10. Do not give chargers and batteries to children
11. If there is a strong smell of electrolyte, an explosion may occur. Be careful. Do not try to unhook the clamps from the battery, there is a risk of sparking. Ventilate the room. Then disconnect the wires.

A monster among hand chargers. Why is she attractive? This is power. According to the manufacturer, it is very powerful and is capable of delivering up to 30 watts of electrical energy. Igor Beletsky presented a review, and, according to his admission, he cannot even imagine how you can squeeze 30 watts out of such a small box measuring only 10 x 6 centimeters. Yes, it just fits in your hand. However, looking ahead, let's say that he managed to squeeze even 40 watts out of it.

There are many similar single-handle chargers sold on the Internet. But their power, as a rule, does not exceed 10 watts. It comes with a very serious set of wires. As they say, for all occasions. Well, for example, the most basic wire with a built-in voltage stabilizer. Pay attention to the positions from 3 volts to 28 volts. Using the switch, you can smoothly set any position and charge your devices. According to the test with a multimeter, everything is clear, even 0.5 volts are left. Anything you need! It was bought from this Chinese store. Name: 30W 0-28V Hand Dynamo Hand Emergency Generator with DC Converter.

The wire branches into 4 more, where there is USB, where you connect your phones, tablets, Power banks. Anything that requires 5 volts to charge. Another mini USB and two plugs. One fits under the laptop, the second goes to the wire, which ends with two alligator clips. This is apparently so that the batteries can be charged. There is also a wire that is attached to the charger and also ends with two crocodiles. They have stickers - red (plus) and black (minus). This is a rarity that you don’t see everywhere these days.

Pay attention to how the wire is connected to the charger. First, each has a metal plug. It can only enter in one single position. There is a special groove, by aligning which you can insert the charger into the plug. The nut is screwed on and clamps the plug. The wire itself goes into the plug and is additionally clamped at the input with small bolts.

The charger itself is made in a metal style. It is assembled from 2 metal halves, with a rubber gasket between them, which means that it is waterproof. The device is held in the hand by a leash, which is tightened and holds the hand tightly. A slight inconvenience is that you won’t be able to completely wrap your fingers around the device, as they will interfere with the rotation of the handle. But you get used to it easily. The ergonomics are rectangular, all edges are rounded, so, in principle, it is quite comfortable to hold.

Checking charging power

For accurate measurements we will use an electronic wattmeter and variable resistance. Let's start with the phone. We connect it and set the stabilizer to 5 Volts. We start rotating and the phone instantly “lights up” and depicts charging. Let's switch to a wattmeter with resistance. Let's see how many watts we squeeze out. We charge at the same pace and observe the wattmeter reading. Voltage 5 Volts, power 5 Watts. Enough to charge any phone. Current 1 ampere. This is an excellent result.

We connect the tablet. The stabilizer has the same 5 Volts. Let's start rotating. 65%. It is written: it comes from the network. Which indicates that the current exceeds 0.5 Ampere. Which is exactly what we need. A tablet will require from 5 to 10 watts. Let's see how much effort it will take to produce such power. Here they are, the desired 10 watts. How long can you turn the handle at this pace? This is quite easy to do. Supposedly, for a well-trained person, it is possible to rotate the handle for half an hour. The author of the video, in his opinion, will last 10 minutes.

For a laptop, there is no question of proper nutrition, only recharging. In reality, this device is suitable for all gadgets. The author is most interested in whether he can squeeze the claimed 30 watts out of the device. Therefore, we now move on to the most important experiment.

Crash test for squeezing maximum power from the charger

Peak power reached 40 watts! The resistance became heated in a matter of seconds. It was impossible to pick it up. This suggests that this device is capable of delivering not only 30, but also 4o watts. It all depends on whether there is an appropriate physical effort at the input. Even without great physical strength, the author of the review managed to show this. For people who go hiking and are more physically developed, this device is a godsend. They can use it to charge their phone, tablet, or recharge their laptop. In case of complete isolation from civilization, this is a very necessary thing. The author of the reviews is pleasantly surprised that the manufacturer did not deceive and honestly wrote the declared power. It turned out that you can even surpass it. The quality is appropriate. Perhaps it was copied from a military model or was made with an eye to military orders. It has no competitor in its weight and size characteristics.

It's interesting to see what's inside the black box. There is a transmission gear mechanism here. What is he like? Plastic gears or metal? It is very important. The most interesting thing is, what kind of generator is here? Cheaper models have conventional commutator motors. For example, those that are on printers. Considering the power, it must be of impressive size. And here it’s only 4 centimeters. It just won't fit here. Therefore, presumably there is some kind of tricky generator here. Perhaps even on neodymium magnets. A separate video with an overview of charging in analysis. All details will be shown.

Or camping with friends - often ends with the fact that already on the second day we find ourselves without mobile communications and the Internet. Most often there is only one reason - a dead battery. Finding an outlet, for example, in the forest is not so easy.

Hello all readers. In my previous articles, a method of charging a cell phone was proposed based on homemade diodes made from old Soviet diodes. This time I bring to your attention a charger made from an old mechanical toy. The principle of operation of the device is very simple - mechanical energy is converted into electrical energy using an electric generator, and then the generator charges a battery with a capacity of 2.4 volts. The charger is also equipped with a 2.4 - 5 volt converter for charging the phone itself.

Let's look at each block separately. A mechanical converter converts vertically or horizontally supplied energy into torque. I took this device out of a toy, but there are plenty of such sets of gears in a DVD player, only two gears - one horizontal with one-sided teeth, the other round, I think everyone is familiar with the principle of operation. Next is the generator. it was taken from a tape recorder and is a regular 9-volt motor. You need to remove the motor cover and throw out the board with the stabilizer that is soldered to the motor contacts. We insert a gear of a suitable caliber onto the motor shaft, and attach the motor to the mechanical converter using super glue.

The second part of the mechanical is the voltage converter. You can find a large number of such converters on our website, but I used this particular circuit. In the circuit, transistor VT1 was replaced by KT816, and VT2 by KT817, but you can use any similar parameters. The choke is a ferrite rod or ring, has 15 turns of wire with a diameter of 0.3 - 0.7 mm. Batteries used two cans of nickel cadmium batteries from home phone. They are connected in series and produce a voltage of 2.4 -2.7 volts. The batteries have a capacity of 400 mAh. The generator is connected in parallel to the batteries, but we put a diode on the positive side of the generator in the forward direction, otherwise it will rotate like a motor.

That's the whole structure, now you have at your disposal a whole small power station, the operation of which is in no way dependent on the weather, unlike a solar panel. Is the battery dead? No problem - with a few hand movements it will charge again. This device works at any time of the day, is small in size and reliable. Such a mechanical device can charge not only a mobile phone, but also a bunch of other things - players, navigators, batteries, etc. One charge of the device’s internal batteries is enough to charge the mobile phone for about 30 minutes, and if it runs out internal batteries- then once, twice - and they are ready to charge the phone again.

The device is indispensable for lovers of hiking and fishing, as well as during travel and vacation. Mechanical charging can also be made from flashlights with generators (they cost 30 rubles), but in this case the generator must be supplemented with a diode bridge, since such a generator produces alternating current which is not capable of charging rechargeable batteries.
