Charg Makita flashes red and green. The most common causes of breakdown

What do symbols mean on the charger Makita?

Red and green glow constantly. The battery is discharged. charger. The battery is charged by more than 80%. It burns green. The battery is completely charged. Red and green flashes. The battery is discharged. It burns yellow. The battery is conditioned.

Then what is the difference between Makita BL1830 and BL1830B?

Makita BL1830 Lithium-Ion Battery 18 in 3.0 ah. MAK-BL1830B. The lithium-ion BL1830B has no memory effect and is much easier than the batteries of another chemical composition. 22-minute recharging in the DC18RC charger, as well as the LEDs of the battery container indicator, which show how much energy you have left, with one click of the button.

Given this, which means Makita LXT? Makita. Technology. LXT. Flying-ionic technology XTREME. LXT.

One battery is suitable for everyone. Instantly switch from drilling holes or cutting the lawn to cutting firewood with one battery for the entire system. Just slip the battery from one makita tool and insert it into another makita machine. 3 powerful batteries all from this assortment offer different time and charging time.

Do not drain the battery. It is recommended to discharge the Ni-CAD batteries completely, at least once every 20-30 days, if you are wanting to live longer. You can leave what the battery is in the charger after its full charge, but only if it is allowed by the manufacturer.

How to charge the battery of the Makita electrical screwdriver

The autonomy of power tools is provided thanks to the battery. By replenishing the container from the power source (socket), it transfers energy to the device. To carry out repair work without failures, it is necessary to control the level of charge of the battery. About how to charge the battery to Makita and how to extend the service life of the energy drive, and will be discussed in the article.

Complete with each Makita screw.fingers are attached to the battery and charger for it. It is with the help of this memory that the drive is replenished. The whole process of recharging can be divided into several steps:

• Elimination of the battery. To remove the battery from the electrical equipment, it is necessary to press on the digging of the element fixation (located on the battery block) and move forward the drive by moving forward.
• Connecting ZU. Before charging the Makita electrical screwdriver battery, connect the charger to the power source. The light bulb blinking with green will be the guarantor that the device is ready to work.
• Battery installation. When you are convinced of the normal functioning of the memory, you can install a battery in it. To do this, insert the element all the way in accordance with the designations “” and “-“.

Evidence of the charging process will be an indicator, glowing continuously red. As soon as the light bulb becomes green (without blinking at the same time), you can remove the battery from the device. It should be removed if the indicator blows in red. This indicates an overheating of one of the elements (ZU or AKB) or the failure of the equipment.

The time of full charge replenishment depends on the type of drive. So, the lithium-ion household battery gains 100% of energy in about 1-1.5 hours. The nickel-cadmium element equipped with the same capacity will be charged for 6-7 hours. The approximate charge time for each specific accumulative component is indicated in the technical technical passport of the electrical appliance.

Practical advice on using the drive

For the correct functioning of an electric screwdriver and extending the life of its battery, you should remember the following rules:

• The first charging (before the first use of the equipment, be sure to charge its accumulative component to the mark of 100%);
• Storage (with prolonged non-use, store nickel-cadmium elements in almost discharged form, nickel-metallological-charged by 100%, lithium-ion-discharged by 50%);
• Replacing the element (with frequent overheating of the battery, it is recommended to replace it with a new one);
• Compatible equipment (use only a charger compatible with it for charging).

In addition, do not forget to monitor the charge indicator and remove the source when reaching a 100% energy level. These simple tips will not make the life of the device unlimited, but largely extend it.

Is it possible to restore the battery for an electric screwdriver without disassembling it? My experience

There are many examples on the Internet how to restore the dead battery of an electric screwdriver without even opening it. I just have two batteries that are not amenable to charging, even if they are charged all night.The recovery method that I will check is suitable for batteries that are no longer charged with a regular device and for those that are fully charged, but their capacity is extremely small for the long operation of an electric screwdriver.

The idea is to serve a short.term large current on the battery. After that, as the authors of such ideas promise, the battery almost always returns to work and lives for a long time.I try to charge my batteries:

On the charger, the red-green indicator flashes. This means that the charger initiates the battery completely not suitable for charging. The tension on it is almost zero.This defect is observed in both of my batteries.Well, let’s try to use the recovery method.

You will need it

I install the minimum current on the welding machine, in my case. 45 a. And connect plus to plus, minus to minus.

A miracle did not happen: the indicator also moves from red to green. I waited a little just in case. Everything too, nothing has changed.Okay, let’s move on to the second battery. Put it with an electric shock for a short time.

What to do after diagnosis

Having installed it reliably which equipment is malfunctioning, you need to choose the path of solving the problem. The simplest action is to replace the faulty block. This path is not always optimal for economic reasons-the batteries and it are not cheap, and throwing them away due to penny breakdown irrationally. And it is not always possible to purchase components, especially for old models.

In many cases, the performance of electrical equipment can be restored. If oxidized or rusty findings of the charger are found, they must be cleaned with a small skin. Better yet, replace the contact plates, taking them from a faulty charger-donor.

This will require a soldering iron, and a solder and a flus based on rosin (vicious). The same applies to damaged contacts of the battery block.

If the network voltage does not arrive on the charger fee, then you need to replace the network cord. You can take it from any other device or do it yourself, by purchasing a fork and a segment of the wire.

If everything is in order, but the charger does not flash with LEDs and does not give out voltage, then the control board is faulty. You can try to fix it. This requires a certain qualification and devices (at least a multimeter and an oscilloscope). The DB scheme can be found in this article.

If there is an idea to use the charger from another electric screwdriver, even the same manufacturer, it is necessary to show marginal. It should be designed for the same voltage, issue sufficient current, and most importantly. should be designed for the same type of batteries. Data on the charger and battery must match.

If the battery is faulty, then you can try to reanimate it, and the recovery method depends on the type of battery elements. For nicd batteries, open the plastic casing of the block and extract all the elements. Next, a visual inspection should be performed, which will help to identify flowing, oxidized, damaged elements. They need to be dropped and replaced with new. If there are no such, it is necessary to measure the voltage on each element.

Lagging banks or elements with zero voltage must be soldered and postponed separately. If the voltage is zero, then you can assume the drying out of the electrolyte. In this case, you need to drill a hole in the battery housing and try to gradually enter about 1 milliliter of distilled water with a syringe inside. If the water is not absorbed, the element is not subject to recovery.

If you manage to nourish the inner cavity with water, then you need to try to recharge each faulty element (including lagging banks) with a pulsed current until a voltage of 1.2 volts. The essence of the method boils down to charging with a current exceeding the container by 10 times with pulses of 2-4 seconds. If the operation passes successfully, you need to seize the hole in the body of the element and let it lie down for several days. Then the battery must be soldered and collected in a plastic case.

Nickel-metallogid elements can be tried to restore the training method. Experience shows that for batteries that have not undergone a deep category, the chances of success are high. For this, the lagging elements must be individually discharge to the level of 1 volt, loading them on a light bulb or resistor. Then charge again to the face value, and repeat this cycle several times.

From the video you will learn: why the Ryobi electrical screwdriver has stopped charging.

It is impossible to restore the capacity of the LI-IN battery, but the battery may lose working capacity with a deep discharge of one or more elements. In this case, the control scheme involves the elements of failed, and blocks their charge. You can try to “pull up” the batteries to the face value so that the balancer does not turn them off when charging. To do this, the discharged element (it can be found by measuring the voltage on each battery), you need to remove and collect a simple circuit.

The voltage must be raised from zero until the current is reached about 0.2 from the battery capacity. In this mode, the element must be charged up to 3.7 volts, and then turn off and control the voltage on it for several days. If it decreases due to self.discharge, then the element is subject to rejection. If not, you can conduct a control cycle of a charge-discharge. It must be borne in mind that even if the performance has recovered, this effect is temporary. The element will soon fail, so you have to be prepared for the complete replacement of the cell cells.

The tips look doubtful to charge a deeply discharged element with large currents from a constant voltage source through a resistor. In this case, the chances of losing the battery are higher than to restore the element. The advice is even more doubtful to freeze the battery before charging.

If it turns out that the electric screwdriver does not charge, then this problem can be solved in many cases. But the approach should be conscious, otherwise the situation will only aggravate and lead to financial losses.

Why does an electric screwdriver not charge and what to do

The reasons why the battery of an electric screwdriver refuses to charge, two are the failure of the battery or its circuits and the breakdown of the charger. First of all, we measure the voltage with a voltmeter on the terminals of the charger. it must correspond to the indicated on the case or be slightly higher. At the same time, the green indicator “Network” burns on many items. We also act with the battery. we measure the voltage on its terminals. It can be slightly lower than the required (the battery is discharged), but slightly. Depending on the measurement results, we decide that we have a faulty. charger or battery.

If your friends have exactly the same electric screwdriver that it is unlikely, then you can try to charge your battery or vice versa. its battery with your own.

Charger

The breakdowns of the charger (ZU) from the electric screwdriver include:

We are convinced that the terminal terminals to the battery is in order. In the photo below they are marked with an arrow. We carefully examine them for oxidation or burning, if necessary, clean. If they are weakened, bend for better contact. To do this, analyze it.

Next, we call the supply wire with a multimeter included in the resistance measurement mode. For this, the device will also have to be disassembled. If you find a cliff, we eliminate. Next. internal breakdown. If you have a simple memory, for example, as shown in the photo, and you understand electronics, then fix the device yourself, focusing on the diagram given below.

The scheme is simple. Do a visual inspection. If the capacitors are swollen, change. Then you arm yourself with a multimeter, measure the voltage at the output of the transformer. If it is, then check with a multimeter (ZAS should be disconnected from the network):

• fuse;
• diodes of the rectifier bridge VD1-VD4;
• smoothing capacitor C1;
• Zener diode VD6;
• diodes VD5, VD7;
• transistor Q1;
• SK1 button;
• Relay JDQK1.

You cannot call the microcircuit, but for reference: it is a setting generator and a set of dividers for 2. In fact, this is an ordinary timer. If you are an electrician, you will figure it out. If not, just replace it. The microcircuit is inexpensive.

The green bulb “Network” on this charger is ignited only after connecting the battery, and the red burns after pressing the “Start” button. charging is ongoing.

If the charger is collected according to the pulse scheme, and you do not have appropriate knowledge and devices, then it is better to entrust the repair to specialists. But if you are determined to try, then read the article “Repair of a charger for an electric screwdriver”. By the way, in the same article you will find a more detailed description of the method of repairing a simple charger, briefly described above.

Battery

These are the main reasons for the failure of the battery of an electric screwdriver:

• Oxidation or burning of contacts of connection to the.
• The failure of the thermal attemptor.
• Refusal of one or more batteries.
• Mechanical damage that caused an internal cliff.

Everything is clear with the contacts. we examine, if necessary, clean. They are in sight, so you don’t have to disassemble anything. The temperature sensor is checked by the call. To do this, we focus on the scheme below. We find the contacts of the battery with a voltmeter (there should be some voltage on it), the third is the contact of a thermal attew. If the battery is not overheated, then the contacts of the thermal attempt must be closed.

Most often, the battery contacts are marked with symbols “” and “-”, so the voltmeter is most likely not needed.

Mechanical damage can be determined visually, but it is better to disassemble the battery and inspect it from the inside for cliffs, chips and other damage, including individual batteries (cells).

Now about the refusal of individual batteries. Open the battery and multimeter measure the voltage on each element. The voltage on the faulty is much lower than the voltage on the rest. Element that is measured in the photo below is no good.

We find faulty. we change to serviceable elements of the same type and electric capacity.

How to correctly charge the battery of an electric screwdriver to extend the service life

The lifetime of any battery depends not only on the number of cycles declared by the manufacturer, but also on proper operation. Consider the main nuances of charging batteries of screws of different types.

Nickel-cadmium and nickel-metallogid

First of all, the value of the charger. The optimal charge and nickel-cadmium battery is considered optimal for the charge of 0.2C to 1C. The way out of these limits leads to the loss of the electric capacity of the battery. It is these values ​​that operate high.quality chargers. To increase the service life, charging is carried out in 2, and a strongly discharged element in 3 stages:

• 1. pre.election. It is carried out with a stabilized current until the voltage on the battery or cells of the battery will rise to 1.05. 1.1 century
• 2. main charge. Charging with a stabilized current until a battery is obtained 90-95% of energy.
• 3. recharge. It is produced with a stabilized voltage of 1.25. 1.27 V on the cell until the charging current falls below 10% of which the main charge was produced.

At the time of full charge of Ni-CD and NI-MH batteries, the voltage on it drops sharply by 30-40 mV. Advanced chargers track this and stop the charge.

During charging, it is necessary to control the battery temperature. If it rises above 45-50 degrees, the process is stopped until completely cooled.

Since the batteries of these types are subject to memory effect, it is necessary to regularly train them. The process consists in complete (up to 0.9. 1.0 in the cell) discharge by current 0.1C. 0.2C followed by complete exercise. The number of cycles/discharge for one training-1-3. The frequency of training depends on the intensity of the use of the battery. Average value. once a month.

Litius-ion (Li-Ion)

The batteries and batteries of this type allow charging 2C current, but to increase the service life, the manufacturer recommends not to exceed 1C. For the execution of the service life, charging should be carried out in 2, and a strongly discharged element. in 3 stages:

• 1. pre.election. It is carried out with a stabilized current until the voltage on the battery or cells of the battery will rise to 3.0. 3.1 century.
• 2. main charge. Charging with a stabilized current until a battery is obtained 90-95% of energy.
• 3. recharge. It is produced with a stabilized voltage of 4.fourteen.2 V to the cell until the charging current falls below 10% of which the main charge was produced.

During charging, the battery temperature controls. If it rises above 45-50 degrees, the process is stopped until completely cooled.

Since elements of this type are not susceptible to the memory effect, they do not need to train them, but can be charged when it is convenient. Even if the battery is discharged by only 20%, it can be visible without consequences.

Step 2 Testing batteries.

I had four batteries failed, and I checked the voltage of the batteries and pairs of elements separately. I found the following:

First part: does not charge a warning about overheating. Also plastic on the side of the release button was bubbled. It shows 7.99 in the entire battery, which is at a very low level, and 0.04 V, 0 V, 3.96 V, 0.04 V and 3.97 V for each of the pairs of cells, respectively. When opening the battery, obvious damage to the second pair of elements occurs.

Battery 2: does not charge with the help of classic red / green flashing lights. It is 12.84 V for the battery and 3.2 V, 0 V, 3.22 V, 3.22 V and 3.21 V for each of the steam elements, respectively.

The third battery: does not charge with the help of classic red / green flashing lights. It is 15.54 V for the battery and 0 V, 3.89 V, 3.89 V, 3.89 V and 3.89 V for each of the pairs of elements, respectively.

Battery fourth: does not charge with the help of classic red / green flashing lights. It is 18.15 V for the battery and 3.62 V, 3.63 V, 3.6, 3.63 and 3.62 V for each of the steam elements, respectively.

For comparison, with good charge, the battery measures about 20 in.

Step 3 Control payment.

The control board was delivered with good installation instructions, but they do not explain everything, it can be because it can be used with all models of the 18-volt battery LXT made by Makita. If you have a little common sense, you should be in order.

Thus, in addition to soldering, you can expect that you will also have to cut a lot of plastic, and this suggests that you are lucky, like me, and you do not need to replace any cells. If you do a spot welding with cells, this is the best way, since if you are soldering, you risk overheating.

As I previously pulled out a battery block from the case, the first thing to do is to remove the existing printed circuit board and cut off the plastic stand for the board, etc. D. According to instructions. I decided to cut nickel contacts instead. Installing the printed circuit board and soldering wires to the contacts was simple, although I had to break my big soldering.

flashes, and red light on the battery is charged by more than 80%. and can be removed from the charger and use it if necessary. Anytime. Perhaps leave the battery on the charge to green light IS hard.

How much watt does the charger Makita have?

It is recommended to discharge the Ni-CAD batteries completely, at least once every 20-30 days, if you are wanting to live longer. You can leave what the battery is in the charger after its full charge, but only if it is allowed by the manufacturer.

Put the compatible Makita battery into the battery charger, charging the light will change from green to red, showing that the battery is charged. If charging lights flashes red, then green, the battery block may not be charged. This means that the battery is probably damaged or worn out.
