How to charge a battery of an electric screwdriver without a charger: Ways

The absence or complete breakdown of the VI of an electric screwdriver stops all the planned work. But, using ingenuity, some available tools, the question of how to charge the battery of an electric screwdriver without a charger, can be successfully solved with success. There are several ways to resolve this problem.

On the battery, or the electrical screwdriver itself, the parameters: voltage (volt), battery capacity (ampere/hour) are indicated. The same current dimensions, identical power should issue it. The charging module from any other apparatus, which has identical indicators, can charge the battery of an electric screwdriver: you need to expose the wires, connect the battery connectors by means of “crocodile” clamps.

We connect an electric screwdriver to a car battery

If you have the same profession as mine, you often go to various installations in places where sometimes there is no electricity. Or it is not yet on your summer cottage. You probably came across a situation where your electric screwdriver “sits down” or is not charged when you need to drill or tighten something. It would be great to have a battery electric screwdriver that does not need constant recharging.

My electric screwdriver 12 volts. Of course, the first thought that comes to mind is to connect an electric screwdriver to a car battery. I read many instructions on this subject, but they were not convenient enough for me or not beautiful enough. My version seems to me much more elegant and more convenient. As a result, I want to transfer a few more of my tools to power from a car battery. So, let’s get down!

Stage 1: We sacrifice an electric screwdriver!

How many of them, lonely standing on the shelves in commission stores or announcements sold on boards. Sometimes lifeless, without batteries. Skil, Ryobi, Dewalt, Bosch and others, are looking for their new owner. They are all shapes, sizes, colors. Various power (9.5 volts, 12 volts, 18 volts, 19.2 volts, 28 volts) and the type of battery (lithium-ion, cadmium, etc.D.). Many of them are outdated. It was easier for their previous owner to throw his assistant and buy a new. Thus, these lost children sit on the shelves collecting dust, while the seller of the commission store finally will throw them away. I tell you about electric screwdriver! Or rather about the use of electrical screwdriver.

So, the fact that we need is a 12-volt electrical screwdriver, which is not a pity to part. Here’s what I managed to buy for 300. (cm.Photo above) this electrical screwdriver did not have a battery.

Block inside

The solution to the problem “Is it possible to connect an electric screwdriver through a charger” can be an alternative option for writing an electric screwdriver. Installing a power supply unit in the devastated body of the tooling of the tool.

Before starting actions, it is necessary to prevent overheating of the block, for which holes are arranged in advance in advance, which will provide air movement, removal of heat. The time of continuous operation by an electric screwdriver with such an improvement is advisable to reduce to 15 minutes.

A finished block is purchased, it is selected by the size of the case, technical indicators. The impulse version of the module is most suitable for use, it is small, light. The use of domestic production modules of the time of the last century is not recommended. They have large volumes with small efficiency.

Unsuitable nutrition elements are removed from the bed, a power supply is laid in their place. Contacts are noted, the case is closed. A collected hybrid gadget is ready to work from the network.

  • The wires can be lengthened for convenience.
  • It is necessary to monitor the quality of the assembly: the design should not be able to touch metal elements, otherwise the short circuit is not avoided. It is best to leave some place between the transformer and the board, which will positively affect cooling.
  • If any parts of the structure are very hot, it is possible to install excessive heat of the modules, or the device of ventilation grooves.

On your own

For users with special knowledge, skills, the problem will not turn out to be difficult “whether it is possible to power an electric screwdriver from a charger without special means”, t.To. Assembling a nutrient unit is possible with its own hands. Instead of spoiled elements, the power module collected according to the scheme is inserted into the case. The outgoing voltage is measured, the wires are transferred, the case is locked.

Tip: the scheme may require an additional load, provide it with the inclusion in the 15W light bulb, which will also provide backlight.

The computer module is also suitable

Another solution to the problem of writing an electric screwdriver is to install it to a computer power supply. This option is applicable to such modules that are equipped with a mechanical switching lever. The positive aspect is that the block is cooled by the cooler, is protected from exaggerations of the load built.In special system.

Such an assembly is arranged only with the use of power modules at 300-350 W and an current of 12 volts, at least 16 A. For tools with a voltage of more than 14 volts, this recording option does not work.

The user may wish to hide an unaesthetic block into a beautiful case, then it is recommended not to forget to arrange ventilation in it.

Car charger

In search of a solution to the question “Can I connect an electric screwdriver to a charger”, you can stop by charging by a car achester block. The modules with manually adjustable current, voltage are applicable. The connection is absolutely not complicated. It is enough to connect the input channels of the tool motor with contacts of the car charger.

General recommendations

All of the listed methods include one stage that unites them. Disassembling the body of the supply module. If the skeleton is fixed on the bolts, then this is not a difficulty, fastening on the gap requires careful opening of the seam by tapping the gap with a hammer, deepening the knife into it.

During installation, observe the direction of the voltage. It should not be supplied to the battery. Therefore, the module is mounted in parallel to supplying contacts, a diode illuminator for a certain power is built into the plus line.

Resume: to the question “can an electric screwdriver work from a charger” have a positive answer, and several solutions, however, caution, some scientific knowledge and dexterity are required.

Charging for electric screwdriver does not charge

Since an electric screwdriver is not a stationary device and requires transfer from place to place, it cannot be connected at the time of operation to the mains and is charged mainly after use. In fact, it turns out that after each prolonged use the question arises: how to charge the battery of an electric screwdriver so that it does not fail in a matter of months, but has been served for many years. This paramount role is played by the correct fulfillment of the requirements for the duration of the charging cycles of battery.

How to correctly charge the battery of an electric screwdriver

The proper charge of charging differs from one device to another and depends on specific factors:

  • Residual amount of energy (for some models it is recommended to wait for complete discharge or, conversely, do not bring to the limit);
  • The chemical composition of the battery, that is, the characteristics of certain metals included in it (metals ions are extremely sensitive to heat, and long, uncontrolled energy exposure can negatively affect the properties of conductors/semiconductors, which will lead to a rapid failure of the battery);
  • Type of charger (pulsed/ordinary).

The role of the individual characteristics of metals in the battery

The chemical composition of the battery is almost the main characteristic that determines the type of charging. It is mainly on the used metal that it depends on how to properly carry out charging and discharge so that the electric screwdriver serves you faithfully for many years. Based on the properties of ions used in the battery, several types of batteries are distinguished.

Nickel batteries

Nickel batteries with an admixture of cadmium (NI CD). Excellently hold the charge, work for a long time, provided that consumers do not begin to uncontrollably charge the device with the slightest decrease in the level of energy. The capacity of the battery will also fall, the device will also work, less time will work if you make frequent charging. It is better to wait until the battery is completely discharged and only then connect the charger.

You do not have to rack your head for a long time about how to charge an electric screwdriver if you buy a small energy.Intensive battery NI CD. Many masters prefer such tool models. Charge the device to the maximum maximum and calmly work until the energy mark does not fall to a possible minimum. In the case of nickel batteries, the principle of “two extremes” acts. Even after buying an electric screwdriver, it is recommended to charge it completely, and only then start using it. When the device is not used for a long time, it is better to leave it in half a charged state. In this case, after a long lull, you will first have to fully charge the battery and only then start work.

Lithium batteries

Lithium batteries also have good capacitive characteristics. LI batteries belong to more modern technologies than nickel ones, because they can be charged without waiting for complete discharge. In addition, recharging does not take much time, and the working session lasts longer than the NI CD option.

Leading manufacturers of electrical appliances, including shchuvuruvo, try to introduce lithium ions into the batteries, which allows them, in turn, to guarantee customers many years of serviceability of the charger and the apparatus itself.

Despite all its modernity, LI models are not devoid of shortcomings. They are more expensive in price and very moody at low ambient temperatures, which negatively affects their energy intensity, stability and time of action until the next discharge (it is noticeably reduced in cold weather). For a long storage of these models without work, it is also better to have a charge of at least 50% and feed the battery with energy once a month or one and a half.

Hydrid batteries

Hydrid batteries practically do not have a harmful effect on the environment, but have a lesser ability to maintain charging in inaction. Their energy intensity can significantly decrease within only 30 days.

In view of such a technical characteristics, the masters are advised to always put the device for charging before use, and if you are going to leave for work and take the device with you, then do not forget to take the charger. Without a charger, metallist batteries will not last long. You will not only not be able to do the planned work, but also risk bringing it into complete unusual.

How to load batteries correctly

To cope with the effect of memory of nickel-cadmium batteries and extend the life of lithium-ion power sources, several important rules must be observed:

  • Immediately after buying an electric screwdriver, it should be charged to the maximum level. If we are talking about NI-CD elements, the procedure must be repeated three times in a row.
  • The temperature in the room where charging is carried out should be within 10-40 degrees.
  • Ni-MH and Ni-CD batteries must be disconnected from the network after the charging is completed. Lithium ion sources of power are equipped with controllers who do it automatically.
  • If you do not plan to work with the tool for a long time, it is better to extract batteries and store them separately. At the same time, it is desirable at least once a month to recharge to the maximum level.

How long does it take to charge the battery? If it comes only to short.Term recitle, it is better to take at least half an hour to it. Full charging should last about 7-8 hours.

Features of recharging electrical screwdriver under various environmental conditions

Despite the fact that each device has its own accompanying documentation and operation Rules, everyone has some general patterns for using the battery:

We revive the nickel-cadmium battery

The screwdrivers equipped with nickel-cadmium batteries have practically the past. But they are still sold, found and even work, since the Ni-CD elements can “live” up to 20-25 years, although they withstand about 900 “charge/discharge” cycles. Another feature of nickel-cadmium batteries-they can be stored in a discharged state. So if you found an electric screwdriver with a Ni-CD-battery in the attic, then it makes sense to try to revive it.

We will try to charge the battery. Any burden capable of providing the desired voltage and current equal to half the battery capacity is suitable.

For Ni-CD elements, such a charging current is normal. They easily withstand the current equal to their capacitance, and even twice as much.

We turn on, try to charge. If the battery takes charging, then we continue. If there is no half.Zero on it, we move on to the plan “g” and “p” (see. Below).

As soon as the voltage on the battery reaches the value of 1.37 V, multiplied by the number of batteries, we stop the process. But that’s not all. Not the fact that the battery is fully charged. Nickel-cadmium batteries suffer from the so-called memory effect. If they were constantly discharged, say, up to 60%, and then put them on charging, then they will get used to it and then they will refuse to work when discharge for all the same 60%. Therefore, we discharge our battery with approximately the same current as they charged. We discharge to a value of 1 V, multiplied by the number of batteries. As a load, you can use automobile lamps or an electric screwdriver itself.

After that, we are completely charged again. Repeat the operation “charge/discharge” 3-4 times. We completely charge and try to use an electric screwdriver. If even after all these manipulations, the battery capacity is significantly lower than the declared, then, unfortunately, in our hands a decrepit, outdoor old man. He cannot be resuscitation.

Plan “w”, pushing

Plan “g” consists in the “pushing” of the battery in short (0.2-0.3 sec) high current pulses. Over, the current should be much (ten times) more than the battery capacity. “Pushing” is better each battery separately. Therefore, we open the battery, find out where each battery has plus and minus. As a pusher, we will use a car battery, but any other powerful source with a voltage of 10-15 V is suitable.

We connect the minus of our element to the minus of the “pusher”, connect one end of the wire to the plus of the “pusher”, and the second end we briefly touch the plus output of the Ni-CD element. Frequency of touches-2-3 per second. As a result of such a burning, dendrites causing microsyps are eliminated, and the battery comes to life.

During the touch, we make sure that the wire does not weld to the output of the battery. In general, it is better to touch with a wire, but, say, the head of the screw, on which the wire is wound. And do not forget about the goggles!

The operation is carried out within 5-6 seconds. We put it on charging. If the process has gone, we eliminate the effect of memory (see. Higher). Try to use.

Plan “P”, Dolnia

This plan is effective in the degradation of electrolyte, because during operation there is a process of oxidation with water consumption. And the plan is:

  • Microdrel make a hole in the housing.
  • Pour 1 cube of distilled water into the hole with a syringe.
  • We are waiting for an hour, then “pushing” the element with high current pulses.
  • We put it on charging. We are waiting for a day, measure the voltage.
  • If the voltage is normal, seal the hole with a sealant or soldering.
  • If it fell or the element did not want to take exercises, go to paragraph 2 and do so until there is nowhere to pour water.

If it did not help, then you can read the articles “How to redo the battery electric screwdriver for 12 or 18 V in the network with your own hands” and “How to make a power supply for an electric screwdriver”. Still better than throwing a working tool again into the attic.

We found out how to charge the battery of an electric screwdriver without a native “charging”. Now, even if the “charger” of your electric screwdriver burned, drowned, lost or stolen, you will find a way out.

Charging the battery of an electric screwdriver: how to charge it correctly

A scorch is an electric tool that is intended not only for twisting or unscrewing self.Tapping screws, screws and other fasteners, but also for drilling holes. The device functioning from the mains can not be used in all places, and in addition, working with such a device is not very convenient, since the cord interferes all the time. To save yourself from these shortcomings, you need to purchase an electric screwdriver with a battery. With such equipment, you can perform work in any place and do not depend on the presence of a socket in the house.

The main element in such screwdrivers is the battery, which allows the device to function autonomously. However, after a certain time, each user of such a tool will have the question of how to correctly charge the battery of an electric screwdriver, and how much time to charge the battery of an electric screwdriver.

Next, we will talk about what an electric screwdriver with a battery is how the battery needs to be charged, how much the electrical screwdriver is charged, what are the features of the battery of the electrical screwdriver, how to charge the battery of an electric screwdriver without a charger, as well as how to check The level of charge of the battery.

Electric screwdriver battery device

The battery is a chemical source of current for the screwdrivers that are unenvaluating from the electrical network, in which the energy of the chemical reaction is repeatedly converted into electricity. Due to this, the battery is able to store electric energy and store it for a long time. During charging, the battery accumulates electricity, and during discharge gives it to the consumer.

  • The case on which contacts are located to connect to the charger or to power tools.
  • “Banks” that are interconnected by a chain.
  • Temperature sensor that allows you to protect the device from overheating.

Characteristics of batteries of electric screwdriver:

  • Voltage. This is a parameter that characterizes the capabilities of the device. What complexity of the task you can do on it. The value of Voltage is unstable: the highest rate is at 100% battery charge, and it gradually decreases during its category. Therefore, it is better to perform complex work with a large level of battery charge.
  • Energy intensity. It indicates the number of accumulated energy by the device. Affects the duration of the device. But you need to know that the work time of the product depends on the complexity of the work performed, so the device with one battery can function differently.
  • Weight and dimensions. These parameters affect the convenience of using the device. A tool that has a large and at the same time heavy battery, it will not work for a long time for a long time, which will affect the effectiveness of work.
  • Charge indicator. He indicates the level of charge and helps to find out what time you need to charge the battery.Nuances of charging batteries of various types

In the screwdrivers, there are different types of batteries-nickel-metallogid, nickel-cadmium and lithium ion. Each type has its own nuances, so you need to recharge taking into account recommendations for a specific type.

  • Nickel-cadmium. The most common type of battery, its advantages are small dimensions, price and significant energy intensity. In addition, this type can withstand a large number of charging and discharge cycles, about 1000. But this battery has one minus. The effect of memory. Therefore, if you discharge or charge the Ni-CD battery is not completely, then its energy intensity will gradually decrease. In addition, the manufacture of nickel-cadmium batteries is very poorly affected by ecology due to toxic emissions, for this reason some countries refused to use this type of battery.
  • Nickel-metallogid. This type of battery also has a memory effect, but in them it manifests itself to a lesser extent, compared with the previous type. For new batteries, you need to perform a cycle of full charge and discharge 5 times. And in the future, charging is carried out if necessary. The main advantage of this type is that their manufacture is safe for the environment.
  • Lithium ion. Batteries of this type are much better than their predecessors. They quickly carry out exercises and do not have a memory effect. Such batteries do not need full discharge, and you can connect to a charger as necessary. The disadvantages of the battery include a large price and poor tolerance of small temperatures. Lithium ion batteries from electric screwdriver must be recharged at a temperature of 10 ° C to 40 ° C.

In addition to types, you also need to know how much to charge the battery in time. As a rule, the duration of the battery of the battery of an electric screwdriver is noted in the instructions for the device. You need to carefully study it and adhere to all the recommendations. It usually has a charge indicator that allows you to find out how the charging process goes. With this element, it will not be difficult to determine how much time it takes to recharge. As a rule, it charges a battery from 1.5 hours to 7h.

But it must be borne in mind that there are 2 types of chargers for the battery. Ordinary and impulse. Conventional ZU is used in the unprofessional device, it recharges the battery for 3h-7h. Impulse charger is used in professional tools. Using this type, the restoration of the container comes from one hour.

Charging methods without using a special charger

How to charge a battery of an electric screwdriver without a charger? If there is no original memory, then you can use non.Standard methods that allow you to recharge the battery of an electric screwdriver without the use of a special charger:

It is better to recharge the battery from the car, which has the ability to adjust the value of voltage and current. The most important thing with such charging is to prevent a reloading. To do this, it is necessary to properly set the current strength. For example, if the container is 1.3AC, then the current value should be from 650mA to 130m.

Universal POS are comfortable in practice. They have a lot of additional. Elements that help choose the best current indicators for charging batteries from various electrical tools.

External sources of electric energy use, as a rule, for old devices that are economically unprofitable to buy new batteries. In these cases, an electric tool is improved in a certain way with the manufacture of a correct connection diagram.

Homemade block

You can make a homemade block. For this they act like this:

charge, electric, screwdriver, charger

  • Take the old battery.
  • To fall out the terminals.
  • Sold the wires, observing polarity.
  • Seal the location of the wiring using dense cardboard or paper.
  • Fix the lid with glue on the surface of the charger.
  • Place the block in the battery through the conductor and conduct test charging.

Thus, even if there is no charging at hand or it has broken, it is quite possible to get out of this situation. The main condition is to configure the current strength and voltage for the parameters of the device. It is also necessary to control the level of charge.

The easiest option is how to check the battery of an electric screwdriver. Using a special indicator on a charger. In other cases, it is recommended to navigate. For full charging, it may take at least 10 hours. That is how much the complete charging of the battery of an electric screwdriver occupies.

Ways to charge a phone without charging, which may come in handy at the right time

With the rejection of the buttons and the transition to the touch screen, a higher energy consumption has come. Therefore, it is far from amazing that the smartphone even with passive use works one to two days. In case the battery suddenly sat down, but there is no charger at hand, you will be useful to the unusual methods given below.

Courageer in the car

For a cigarette lighter, or rather its nests, there are many devices from a stationary USB port to wires with special connectors. Such devices can serve as a substitute for charging, acting as an adapter from USB to the network, or directly connecting to the battery. You can purchase them in most household appliances or in road stores or workshops.

Charging the Frog

In fact, the horn-hammering is a stationary universal charger. Its versatility lies in the fact that almost any lithium batteries can be charged from it, both for the phone and for the camera, navigator and other devices. The key feature of the frog is that the battery terminals are directly connected to the charms of charging. This complicates the process of use, but often this approach is more effective than traditional. The disadvantage of the method is the inability to use it on devices with a built.In battery.

Finger batteries

In some household stores and in the open spaces of Aliexpress, you can purchase a special portable device for charging a phone using finger batteries. It takes a little place, does not overheat and is cheap. True, in terms of effectiveness, the device can be called only satisfactory, since new batteries are constantly required to work, and they charge quite slowly. But if the batteries and time are in abundance, then this is a completely acceptable option as an alternative to a charger. And if there are the necessary materials at hand, namely resistors and wires, then such a device can be made independently using a soldering iron.

Dynamo machine

If you have no batteries in excess, but there is time and, importantly, patience, you can try to charge the phone with a dynamo machine. In fact, this is an inexpensive portable device, most often small, which converts mechanical energy into electric current. The output voltage is 5V, which allows you to safely charge the phone. Mechanical energy will have to be generated by twisting the pen or clicking on the lever, so the lesson is quite boring and long, although several minutes of work will be enough for a call or message, moreover, you can simultaneously charge the phone and use it.

Lemon, nails, copper cord

In a situation where you do not have a car, nor charging, nor dynamo, no even batteries, lemons can help you. Lemon juice is acid, and, oddly enough, electrolyte. Having stuck electrodes into lemons, which can even serve nails, and connecting them with a conductor, for example, a copper wire, you can get a battery. On average, one lemon gives out 1 in the voltage, so it is worth connecting five or six at once. Such a circuit is able to produce voltage for a rather long time and slightly charge the phone.

Non.Discharge phone is not at all a hopeless critical situation. There are many analogues to a charger that is easy to use.

Why the battery of the device quickly sits down?

Since an electric screwdriver is not a stationary device and requires transfer from place to place, it cannot be connected at the time of operation to the mains and is charged mainly after use. In fact, it turns out that after each prolonged use the question arises: how to charge the battery of an electric screwdriver so that it does not fail in a matter of months, but has been served for many years. This paramount role is played by the correct fulfillment of the requirements for the duration of the charging cycles of battery.

The proper charge of charging differs from one device to another and depends on specific factors:

  • Residual amount of energy (for some models it is recommended to wait for complete discharge or, conversely, do not bring to the limit);
  • The chemical composition of the battery, that is, the characteristics of certain metals included in it (metals ions are extremely sensitive to heat, and long, uncontrolled energy exposure can negatively affect the properties of conductors/semiconductors, which will lead to a rapid failure of the battery);
  • Type of charger (pulsed/ordinary).

Is it possible to charge a lithium-ion battery without a controller

Many are interested in whether it is possible to recharge a lithium-ion battery without using a controller. In fact, it is possible. However, you will have to carefully monitor the voltage and charger indicators. It is impossible to allow them to be too big. The fact is that increased values ​​can lead to the fact that the battery will fail and then it will not be possible to use it.

To protect your electric screwdriver with a lithium-ion battery, you will have to independently limit the maximum charging current. Only in this case it will be possible to recharge without using the controller.

Additional Information! This recharge method is extremely rare, since many people do not want to constantly control the voltage. It is better to use universal chargers. With their help, to charge the sowing electric screwdriver is much easier.

Some people do not know how to charge an electric screwdriver without a charger and immediately buy a new charger. However, in fact, it is not necessary to do this. There are several effective ways that allow you to recharge the tool at home, even without using a corporate party.
