How to charge the DEKO electric screwdriver. Storage rules for the battery of an electric screwdriver
Why may not be charged with an electric screwdriver battery
Over the past decades, the battery tool conquered from the usual network power tool even those niches where the dominance of traditional equipment seemed unshakable. Even shock drills are available with food from portable batteries, not to mention ordinary screwdrivers. Despite the overall high reliability of the battery tool, the nutrition elements are still the weakest, as well as, to a certain extent, chargers for them. Having discovered that the battery of a portable electric screwdriver is not charged, it is necessary to localize the malfunction and decide on the repair or replacement of the faulty unit.
The most common reasons for the failure of the batteries include:
- Corrosion and oxidation of contacts due to storage in high humidity conditions;
- Deep discharge due to prolonged non.Use;
- Development of the resource of the charge-discharge cycles;
- The lithium-ion batteries may fail the internal control scheme;
- A large loss of container due to the “memory effect” of the battery prone to such a phenomenon;
- Drying of electrolyte during prolonged operation or storage;
- Mechanical damage (including internal) due to blows on the battery body.
Chargers often lose their performance due to:
- Corrosion and oxidation of contacts caused by the same causes;
- Hidden cliff of the network cord (most often near the case or fork);
- Failure of internal components;
- Bent contacts due to mechanical exposure.
To make a decision on an attempt to restore the performance of the nutrition elements and the charge of replenishing the charge, it is important to determine the true cause of the malfunction.

Hello, dear friends! My name is. Alexander. Feel free to ask questions that have arisen, I will try to answer everyone, though with a reservation. As you busy!
Only today I thought: how to choose a battery drill shurupert? I will answer about this at the end of the review.
Today, the conversation will be about the batteries of the DEKO 12B GCD12DU3 SET 3-Li-Ion in the case of the equipment 13 pcs, 32nm, 2×1.5ach, salary, which can be ordered and selected here.
Battery Drill Shurovyrt, made of black material with a yellow trigger switch of the operating mode of operation. Has two Li-Ion batteries of one and a half ampere-hour each.
The batteries of the DEKO battery, is in a black plastic case and equipped with two yellow latches, while there are no complaints about the latches, they close and open normally.
The case does not have, any partitions and a battery drill with an additional battery, a charger, are in it in an unsettled state! You have to come up with something to soften blows and movements when carrying!
It is difficult to put something on the case, except for the package with additional drills and taps of not large sizes.
The battery drill-shurupery is equipped with a bright backlighting of the working area, which lights up with a slight touch of the trigger. By the way, the trigger is made of yellow plastic. The light indication green-yellow-red also lights up, when working, like a traffic light. (Cm. In the photo from below, above the yellow trigger).
The battery is inserted into the handle of the drill, which is a dignity. Very convenient, true. Is pulled out with some difficulties!
The battery drill-shurupert, has two rotation speeds (the mechanism of speed switching in the lower photo. Yellow color).
Li-Ion Battery is equipped with a green LED, which lights up at the end of the charge and red. Informs about the start of the charge.
The discussion is approaching the final phase, I have to only warn you that the decision. Buy or not, battery Drill DEKO 12V GCD12DU3 SET 3-Li-Ion in the case of equipment 13 pcs, 32nm, 2×1.5ach, salary. Accept only you, and I have already made my choice and shared with you!
Dear friends, I promised to write to you how to choose a battery drill shurupert? I will answer like this:
First of all, according to the manufacturer. Preference, almost always, are selected by the batteries of well.Known brands, I will not list, so as not to make free advertising;
P.S.:. Ozon employees openly refuse to pay me money for low.Quality goods!
Dear friends, I present to your attention a selective list of my works:
Battery Drill Drum Deco GCD12DU3 Li-Ion Set 4 in the case of equipment 13 pcs, 32 nm, 2×2 a/h. Review
Hello, dear friends! Allow me, before starting my work, introduce myself. My name is Alexander. Feel free to ask questions, I will answer them with pleasure, though if there is free time.
Recently, on sale, you can find a huge number of batteries-scourges-sprayers! How to figure it out? Which is better? Everyone praises his acquisition and in his own way, will be right!
At the end of the review, I will leave links to the batteries I have purchased, and for now we will begin to discuss
In less than a week, I became a happy owner under the marvelous name:
The batteries of the DEKO GCD12DU3 Li-Ion Set 4 in the case of the equipment 13 pcs, 32 nm, 2×2 a/h, which you purchased here and here you can choose the appropriate electrical screwdriver in the case.
A plastic case, equipped with two yellow plastic latches, which so far open and close clearly, without “jamming”.
I really admit that the very first opening of the case, all the contents simply fell out, which is not very pleasant! The manufacturer could be worried and equip the case with additional partitions? At least from cardboard! Maybe I’m finding fault, but this is my opinion.
During the charge, the red LED lights up on the battery and at the end of the charge. The green LED lights up.
Unfortunately, Chinese manufacturers have not yet thought of how to equip the battery with one LED, which changes its color depending on changes in the voltage of the battery.
Such batteries are already produced by Chinese manufacturers, but under a different brand! Of course, I will try to publish these works, but so far they are in the stage of projects!
The charge time of one battery is about an hour and a half, which is acceptable with such a capacity!
Battering Drill Electric screwdriver Deko DKCD12FU-LI. Review
I purchased an electric screwdriver in 2020 to help a more expensive branded screwdriver Bosch GSR 180. And I can say that I was not at all disappointed. Before buying, a new Chinese brand was a little afraid, before that he managed to purchase a laser level under the Deko brand, was very pleased with the quality and functionality, and therefore decided to further trust this brand and acquired the DKCD12FU-LI electric screwdriver of the DKCD12FU-LI
DEKO products are produced by Zirtek founded in the Czech Republic, but production is located in several countries. China, Russia, Hungary, Croatia. The electric screwdriver of this model is supplied in various trim levels. I purchased a set with a case, two batteries, a charger and a set of tools.
In general, as it turned out later, the case. Only takes a place, never once used it. A set of tools, namely a set of bit and drills of rather low quality. The drill is soft, suitable only for working with wood. The drill is so soft that they can even be bent. If anyone does not know, then a normal drill from high.Speed or instrumental steel. Does not bother, but breaks with great effort, but it is quite solid and wear.Resistant.
There was also a plastic box with a set of nails, dowels, bots and screws of some goals complete with an electric screwdriver. I immediately threw all this, since in the set lay such a poor and unnecessary trash that I would never use.
If you rarely use an electric screwdriver, then most likely it will be convenient to store in the case, but for two years I have been using it almost every day, and therefore I forgot about the case. I got it only now for a photo shoot. The fact that electric screwdriver has been operating with almost daily use for two years, he says about a good quality of the model itself.
The steady torque at 28 N m most likely does not correspond to reality, according to the sensations, the real torque is about 20 n m. When the torque exceeds the torque, the engine of an electric screwdriver simply stops, goes into defense of the flow, such a stop greatly discharges the battery. During the start of the engine, as well as during the exceeding the maximum moment, the engine experiences an extreme load, with a stopped rotor, the current strength in the winding strives for a short circuit current, and therefore there is a strong discharge of the battery. But the excess of the moment occurs quite rarely and you can even intuitively feel that the screwdriver is difficult and it was time to reduce the load.
The capacity of the lithium-ion battery as stated by the manufacturer is 2000 MAH in my opinion is also a little high, but it’s hard to say for sure, you need to measure. In principle, one battery is enough for 25-40 minutes of continuous work. At first, one battery from my kit was very quickly discharged, then it somehow began to work longer.
The battery size is standard for Chinese screwdrivers, now there are many models on sale from other manufacturers with the same battery. The battery voltage is 12 volts.
Charging nest for a 5 millimeter plug, such as old Nokia. By the way, this charger approaches other devices, for example, to the projector and laser level of DEKO.
On the sides of the battery there are latches, securely attaching the battery to the screwdriver, by clicking on the latches, you can easily remove the battery for replacing or charging.
The charger is very compact. I don’t know how good it is that it looks like charging for a mobile phone, but I like its compactness, does not take up place, like other zhu for screwdrivers. But with such compact dimensions, the charger cannot issue a large charging current due to which it charges with small current and, accordingly, for a long time. There is an indication of the charge on the ZU, when the battery is charged. The bulb burns red when the battery is charged. Green.
There is no information about the current and output voltage on the ZU, only the frequency and value of the input voltage are 110-240 V/50-60 Hz. Judging by the time of charging of one battery, which is about two hours (although the passport is announced at 1 hour), we can conclude that the power supply issues about 1 amperes for charging the battery.
Fast.Raised cartridge with a plastic case. Maximum clip diameter up to 11 mm, although according to the passport. 10mm. The cartridge is perfectly clamping, does not jam, does not beat when rotation, it is easy to unclench and squeeze the tool.
This model has two speed modes. 1st reduced control range 0-350 rpm and 2nd increased with a range of 0-1350 rpm. You can change the speed using a switch located the upper part of the electrical screwdriver.
What can you assemble a power supply
The power supply for charging electric screwdriver can be made according to various schemes. It all depends on the qualifications, the availability of devices and available materials.
From a computer BP
A good power supply for an electric screwdriver with a voltage of 12 V can be obtained from a BP for a computer. First you need to check whether it is suitable for parameters.
In the above example, the BP has two 12-volt channels-at 11 A and 13 A. Each channel is enough to power the selected power tool for 12 volts. On the Internet you can find tips on the parallel connection of the channels until the total current is obtained (in the given case. 24 A). It is not recommended to do this, because due to the difference in stresses, one channel can become a consumer for another. All the risk of choosing the owner. A loop of wires comes out from the power supply. Everything must be cut except:
Sometimes you need to leave a red wire. Some schemes require the basic load. To do this, between red and any black, you need to connect a 12.Volt light bulb. If in its absence the PSU does not turn off, then it can be removed. The green wire must be connected to any black. And 12 volts remove from yellow and black (any) conductors.
From the transformer
If there is a suitable transformer, you can build a power source on it. The general scheme of an unstabilized power source is shown in the figure. Such a device consists of:
If there is a ready.Made industrial transformer, you need to find his data according to the directory. If they arrange, BP can be assembled on it. If not, it can be redone by first checking its suitability for work in the required conditions. The suitability of the transformer is determined by its power. If you set the output current of 10 A, a voltage of 14 V and the efficiency of the system (from the transformer to the output shaft of an electric screwdriver) equal to 0.5, then a transformer with a power of P = 10 A14 V/0.5 = 280 W is required (you can round up to 300 watts ).
To determine the power of the transformer by iron, you need to find the area of the cross.Section of its core in centimeters (in most cases you can remove the dimensions without disassembly). The resulting area in square centimeters SC must be substituted in the formula:
Deko DCS3 6DU2 Cordless Screwdriver
Tuoye Mini Cordless Screwdriver | Converted to Li-on Battery | Power Bank Compatible!
If the result is exceeds 300 W, the transformer is suitable for the manufacture of a power supply. Next, you need to remove all secondary windings and wind up a new. The number of turns can be determined experimentally. To do this, you need to wind any known number of turns with any wire and measure the output voltage. Suppose, having wound 10 turns, the output is 5 volts. So, one volt has two turns, and to obtain 14 volts you need to wind 28 turns. For 10 ampers, the cross.Section of the wire must be at least 2.5 kV.Mm, this corresponds to a thickness of 1.8 mm.
After the manufacture of the transformer, you need to choose diodes capable of working at the selected current. They must be put on radiators. And the last is to install a smoothing capacitor. It should be designed for a voltage of at least 25 volts and have a capacity of 4000-10000 μF (more can increase, but the dimensions will increase). For such tasks, the transformer power supply is quite bulky and heavy.
It can be supplemented with a voltage stabilizer, then it will maintain torque at any load (but this is not necessary. After all, in the normal mode, the batteries also sit at a large current).
You can assemble a stabilizer on an integrated chip of the 78xx series (79xx for a negative shoulder), destroying it with an external transistor.
Important! The linear stabilizer works with a certain exceeding the input voltage before the output, so in this case you will need a transformer with an output voltage 17.18 volts. The overall power should also be increased. The total efficiency of the scheme will decrease. This must be taken into account when selecting or manufacturing.
The finished source must be placed in the case. It can be done on your own or pick it up with ready.
From the laptop
A good result can be obtained by applying the side of the power from the laptop. Such devices are designed for the output voltage of 19 volts and for various load currents. You can choose source that issues a current up to 6 amperes, this is enough for most homework. You should not overload such source. The protection will work or the self.Healing fuse at the input will turn off (it is not always restored independently, and you have to replace it).
To power an electric screwdriver, you can use adjustable and unregulated DC power sources used, for example, in laboratories. Their advantage is that the output voltage can be adjusted and installed, depending on the power tool model, both 12 V and 18 V. The problem is that it is difficult to find a laboratory voltage source designed for an output current 10 A. So, the block presented in the photo for each channel has a current limitation of a slightly more than 3 A. The voltage is about zero, so the electric screwdriver will not be able to work in this mode. At best, this power supply will provide an idle power tool.
The best option is the impulse power source. Light, compact, does not contain a powerful heavy transformer due to the fact that the transformation of the voltage level occurs at a higher frequency. The disadvantage of such a solution is a complex circuitry. To make a pulsor with your own hands, a certain qualification will be required.
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.
What to do if the battery is not recharged?
If the technique does not charge, the reason is in the failed battery or in a damaged charger. Sometimes his terminals and battery begin to interact poorly, to eliminate the problem of the BURS, they disassemble and bend the contacts.
Sometimes during the showdown it is found that the terminals were oxidized or contaminated. To eliminate the problem, they are wiped with a special remedy for cleaning or alcohol.
If the capacity of nickel-cadmium batteries decreased significantly, they can be tried to disperse. To do this, they are disassembled, with the help of a multimeter they find non.Working elements and recharge with a higher current, after which they re.Discharge. Thus, you can partially restore the capacity. Another solution is to disassemble two batteries, remove faulty banks and connect whole. After that, the restored device is charged and discharge several times.
Types of charging devices
In the kit, one or two battery with a charger is attached to the screwdriver. Now the manufacturers of the power tool have a trend for the sale of products without batteries. This marketing technique forces buyers to purchase models of manufacturers already available in their arsenal. In any case, if the battery is purchased, even separately, you can take it to it. The matter is still in the mechanical design. The charger of one manufacturer is most likely not suitable for charging another.
Almost always, the device for replenishing energy is optimized for a specific type of accumulators, charges it in the most favorable current mode, stops charging automatically at the end of the process. Therefore, when purchasing a charger and batteries of one manufacturer, you can not think about compatibility if the ZU is designed for the battery of the same manufacturer and type.
In most cases, it is sold in impulse performance. But for nickel-cadmium batteries, there are charging devices that are considered professional (appropriate cost). They are called impulso-revervation. For each positive impulse, they give out the release of negative polarity of a small amplitude. This eliminates the memory effect characteristic of the NI CD accumulators and their capacity is maintained.
The magical power of chemistry or how I washed my specialists
Was recently on the dismantling of the laundry. They disassembled the equipment, exported, sinker, all that. Especially for dirty work, I took a jacket from a special car with me, which is not a pity. Kill and throw it away.
Recently, a corner grinding in this jacket has been working a lot and all this bell history has settled on a jacket. A couple of times in it climbed the floor of the garage when he took off the bumper.
Overall. Washing in a car with preliminary cleansing of household soap did not have any effect.
But on the laundry, he asked to cast “something that can be used at home”. They gave me a “Devantol Super” cleaning tool, the main detergent “TREBON 2” and a little “Lizerna Intensive”. This is all not advertising. There are other manufacturers and other drugs. Dali that they gave. But the ginger tail is not twisted)
The remedy for stripping was divorced with water 1: 3 and a brush closed (they said, not to rub, namely, injected) this tool and waited 15 minutes. I poured two other components into the cuvette of an ordinary washing machine and washed in 40 degrees “jeans”.
The result, to put it mildly, dumbfounded. I did not expect that this could happen.
Yes, you can find what to get to the bottom of and say “not, well, not new,” but I am delighted.
How is Jesse Pinkman not to quote here: “Science Bitch!”
In general, wear clean, be tidy, even if it is a special forces. All joy!
