Which Makita batteries will fit?
There are a number of features to consider when choosing a battery:
The battery capacity, measured in ampere hours, determines the run time of the tool without additional charging. Household tools have a capacity of 1.3-2 A/h, while professional models have a capacity of over 2 A/h.
Short charge times allow for faster tooling speeds. Inexpensive household tools take 2-12 hours to charge. For more expensive professional models 0.5-1 hour charging time is sufficient. Lithium batteries and pulsed battery chargers provide faster replenishment.
Batteries can be 3-36 volts. Tool voltage readings may vary for the same torque. Batteries with high voltage maintain the maximum capacity of the device for a longer period of time before the charge drops.
Cordless angle grinder (angle grinder) 800W 18V (Makita battery)
A small review (comparison) of cordless angle grinder (angle grinder). The beauty of wireless compact grinders. you can cut or clean up without any fuss. And there is no need to unwind the extension cord, and you do not need to balance at height with a large corded angle grinder. zzzhik. and that’s it. And in this case, also the price is great (37).
As a matter of fact, I have already mentioned this angle grinder (reference to the action at 36). We will talk about a particular model of angle grinder, which runs on battery power type Makita 18V.
Features: Type: Cordless Brushless Angle Grinder Features: Adapted to 18V Makita battery Power:18V Power:800W HX Speed:10,000 rpm Spindle diameter: 14mm Wheel diameter:100mm
A little distraction, tools. The Chinese, of course, are good. Released a series of tools that do not copy, but complement the well-known brands. You can find carcasses for cordless tools like Makita, Bosch, DeWALT and more. You keep the old batteries, and you can order any additional tool you want. A concrete example: I bought on sale a Makita electric screwdriver set two batteries case charger. electric screwdriver is not enough for me, I bought a nutrunner to it. Review on the wrench was, great tool, 1/2″ seat, brushless motor, 100nm does! At the link to the wrench in the lot is the charger and batteries (non-original) In general, such a way you can buy a lot of tools for one (!) battery: cordless jigsaws, circular and saber saws, blowers and peorators, impact drills, and more.
So, as for the angle grinder itself. a regular cordless (cordless) compact angle grinder.
Length is convenient, only 320 mm. Lightweight. With a battery of 5.A 0 Ah, a bit heavier, but not the point.
Included was a shroud, nuts, washers, wrench. Battery is already looking for separately.
The battery is a regular Makita type DGA504Z for 18V. Note, the soleplate has an indicator, and two modes of operation (more revolutions. less revolutions). At low speed is convenient to work with brushes. With the battery looks a bit bulky, but the balance is more or less respected. The power button, or rather the slider, is standard. This point is implemented as well as others, there is no discomfort when working. Gearbox is metal, the direction of rotation is marked, lock the shaft. Small spindle, M10, for small disks.
Yes, the kit had a wrench. For comparison, an angle grinder from Wosai. They are twin brothers, run on the same type of battery, you can switch from Makita to Wosai.
About this angle grinder, I also did a review
And also an angle grinder Worx
The design is the same for all, the dimensions are more or less the same. For comparison, the hoods of Wosai, Worx. I bought a separate shroud for 125mm under worx. The one from the angle grinder goes for 115. Examples of links: cheap, lot to choose from. The diameter of the seat is 42. 44mm.
Now about the seating for the disk. Originally designed for 100/16mm disc, thin spindle. Basically fits 115/16mm max. Here is how it looks with original nut. Under the big disk will need to be installed spacer rings or “modernized” nuts and washer for 125/22mm. The disk fits well on such “modernized” ones, with the enlarged cover it works, there is no runout during work. I do not recommend working without the hood.
Yes, there was a handle in the kit
This is what it looks like with the handle I use it seldom, because it becomes uncomfortable and more bulky. Handle can be repositioned to the other side.
Just in case, check the gearbox. Closed bearing fitted, grease present.
So, the angle grinder is equipped and ready to go. In the background is the home band saw Grinder))))
What can I say about the results of the work (I tried a strip 4mm, angle, pipe, etcп.). Saws more or less. Suitable for short term work on thin-walled metal. Saws bars and small items with no problem. Under a heavy load, on the other hand, it’s the fault of the cheap battery. It just doesn’t deliver the current you need and it cuts out (electric screwdriver battery). If you have the original Makita 18v batteries, especially the 5 model.0 Ah (high-current), then this angle grinder is your choice. For funny money you get a useful tool. But if you need to buy a battery charger and batteries as well, I would think twice. The angle grinder, on the other hand, handles small tasks (e.g. sawing off a bar, a small corner, scrape off rust). If you compare a small angle grinder to a large one, of course it loses out in power, and will not replace a full-sized mains angle grinder. But it’s a great addition to it.
To take or not to take. you decide. The quality meets the price. Of the more expensive ones, I can recommend something like Milwaukee 2780-20 or DeWALT DCG412. A little more expensive, but more powerful.
Thank you for your attention!

What is Prostormer and why they have different battery voltage
Prostormer. the chinese brand on aliexpress. They make pretty good quality tools. By the way, if you are going to buy something, read my tips how to buy cheaper.
Prostormer has two lines of batteries. Some are similar to Dewolt 18v batteries. Chinese called it 20v max lithium.
Others are similar to Makita 18v. They call it 21v max lithium.
Inside both batteries there are 5 or 10 (depending on the capacity) 18650 cells. Each cell, depending on the degree of charge, has a voltage ranging from 2.4V to 4.35В. Nominal value 3.7V, but that’s just the labeling. Brands write “18v” on these batteries ( 5 3.7 = 18.5 ).
Chinese marketers apparently proceed from the idea that if you write more, it will be cooler. Especially since it’s impossible to fault. on such batteries, if fully charged, the voltage is even more than 21v ( 5 4.35 = 21.75 ).
This also applies to branded “18v” batteries. the battery has the same voltage as a regular Makita battery and it needs to be charged at least once a year. Inside all the batteries have the same cells, and electronics only balances the charge of the cells, but does not limit the output voltage of the battery as a whole.
Makita sometimes sells tools without batteries at very competitive prices.
But a set of one battery charger will cost you as much as two Prostormer 21v electric screwdriver along with a battery and charger each.
If you already have Prostormer line 21v max lithium tools. you don’t need to buy anything extra at all.
If you put a Prostormer 21v max lithium battery into a Makita tool, it just won’t turn on.
And that’s where the “wise” Makita salespeople come in from over their shoulder and start telling tales of what super batteries and super protections Makita has.
But the real reason is that the Chinese do not put a thermistor in their batteries to protect them from overheating.
The resistor is connected to the battery’s plus side and terminated at the center contact (the one closest to the plus side). The Makita tool measures its resistance and if it is too high, which signals that the battery is overheating, the tool is turned off.
My experience with Prostormer tools shows that the batteries do not overheat to any noticeable degree, so the lack of temperature control does not affect anything.
That’s why I didn’t try to match the thermistor, I just put a plug instead. A normal resistor of 20K ohms. If you don’t have one handy, you can quite safely just wire the middle contact of the thermistor to the plus contact (the one closest to it).
There is only one problem. the chinese, although they didn’t use the middle contact of the battery in any way, “optimized” the layout of the circuit board and ran one line through it.
So before you connect the center and side pins, you need to rewire the tracks connected to the center pin. There are two of them, one on the bottom and one on the top of the board. And replace the broken connection with a wire.
How I did it can be seen in the photo. In the white tube is a heat shrink. my resistor, which, as I said, you can simply replace with a wire.
When reassembling don’t forget to put the button spring back.
After this conversion, the battery will work in Makita tools. Charge normally with their regular charger. And will continue, of course, to work in the Prostormer tools, because they don’t have that center contact at all.
What kind of tool do Makita batteries fit?
For more than 100 years, the Japanese brand Makita has been delighting its customers by constantly improving the quality of its screwdrivers. The manufacturer’s range includes both battery and mains models. Which one you prefer and why, as well as the intricacies of working with a lithium battery screwdriver, will be described in this article.
Virtually any screwdriver from the Japanese maker can replace a toolbox completely. It’s great for working with a variety of classic fasteners. This screwdriver is comfortable and functional to use.
The 18-volt power and robust gear box allows even large-diameter screws to be installed without fear of poor performance or quick breakage. The screwdriver power control button is located on the rubberized handle of the device, making it most comfortable and safe to use.
Additional features, such as speed switching and backlighting, allow you to quickly and efficiently perform the necessary steps with this tool.
If you buy the latest versions of the Makita, you can also use it as a drill if needed.
However, in this case, it is better to choose a screwdriver that is sold with a self-contained charger and does not work directly from the mains connection.
Japanese-made screwdriver motor has an excellent durability, does not overheat, and some models have an overheat function. Screwdrivers with battery replacement may not work if the battery charger is connected. This can lead to overheating and premature device failure.
In general, all Makita screwdrivers are characterized by
- high functionality
- reasonable price
- continuous operating time
- additional warranty from the manufacturer
Today it is difficult to find the manufacturer of such devices with such combination of price and quality.
Like any other tool, screwdrivers from Japanese manufacturers have their pros and cons. There are many major advantages.
- Universal use
- Almost completely self-contained
- The cost of spare parts is lower than the price of competing brands’ products
- Light weight, which makes using the screwdriver uncomfortable and the feeling of hand fatigue
- There is a special button for a smooth release and a sharp brake of the work
- Stylish and modern design
- Reasonable price
- The warranty period of the original device is 3 years.
There are also minor drawbacks that can be quickly eliminated if necessary.
- Having done a lot of work, you can quickly start the engine. In this case, it is enough to buy a special improved gearbox, and this disadvantage will be eliminated.
- Low screwdriver power or low backlight. It’s difficult to fix this defect on its own, but it can be avoided if you buy the right tool for the right job.
The advantages of these tools are much more than the disadvantages. So it’s no wonder that the number of Makita fans is increasing every year.
The manufacturer now offers customers a wide range of tools. They can all be divided into several large groups:
- Mains or battery powered. They differ in how they work: from a direct connection to the mains (electric) or from a replaceable battery (standalone). For small amounts of work, it is better to buy the second option. At the same time, electric tools are more suitable for private and long-term use.
- The belt device greatly facilitates a large amount of work and reduces the total time required. Self-tapping screws are consistently inserted into a special moving belt, which, when the screwdriver is on, moves independently.
- Cassette tool. The usual standard, which is more suitable for home use. It does not have the same function as the previous model, each screw must be set independently.
- Professional and household units. They differ in power, equipment availability, speed. However, both types can be equipped with or without a lamp.
- The brushless screwdriver has a special brushless motor. It is in these tools that you can change the intensity and speed of the device itself quickly and over a wide range. The new generation of household electric screwdrivers are nearly all brushless.
- Impulse and shock tools are different from the motion of a drill. In the first case, it is intermittent and more intense, in the second. Smooth and sliding.
- Classic and Angle electric screwdriver In the first case, the model is more compact. It has a long handle and short top working part. This is what makes this tool most suitable for use in hard-to-reach places.
- 12 volt, 18 volt, 220 volt. This marking indicates the battery charge and the voltage of the battery to charge it. The higher that number, the more powerful and stronger the screwdriver will be.
So you can use Makita Lithium-ion power tools 18V. 100% compatible with Milwaukee 18V / DeWALT 20V Lithium Ion Battery and Makita Lithium Ion Power Tools 18V.
However, the Ridgid are a higher quality tool than the Robe. Ridgid seems to be much more popular because of their larger equipment such as vacuums, group boxes and some larger machines. I’ve seen a lot more of those at work than their cordless tools. Ryobi. HD exclusive brand.
Makita 125mm cordless angle grinder
Some time ago I have not posted reviews of power tools and got into my hands a cordless angle grinder, and designed for a standard “Makita” battery and moreover, with a commutatorless motor.Today in the review inspection, disassembly, some tests and a little bonus.
Let me start by saying why a cordless. I often see Комментарии и мнения владельцев like: Why a cordless tool, you can take an extension cord and use a regular one, and you can work indefinitely (conditionally), not until the battery runs out.Of course you’re a hundred times right, but in its own way. I have a network angle grinder, but when I was doing repairs, I noticed that the cordless tool is used much more often than a corded tool, and the reason is simple, it has no wire, which in a pile of things on the floor is constantly getting tangled up, gets under your feet, trying to get under a saw, drill, etc.п. As a result, the cordless tool is used in large areas, where you do a lot of work in one place, and cordless where you need it “here and now.Unlike an electric electric screwdriver or drill, peorator, and oscillating saw, the angle grinder is not a tool I use often, but nevertheless, in my opinion it can still be useful.
There was no original packaging, just a plain, unsightly cardboard box, crumpled in some places.
The set is also very laconic:1. USHM2. Protective cover3. Handle4. Wrench
Even though some of the stuff was additionally in a bubble bag, there was still something in the box if you turn it upside down, as for me, you could take a little more responsibility for the packaging, especially for a fairly heavy thing. But nothing was damaged.
The key, handle and cover are the same as the others, except the cover is pretty good painted, because during the transportation it got out of its bag a little and the key was banged on it, but there was not even a trace.
And the angle grinder itself. The color scheme is somewhat reminiscent of Milwaukee tools, like their oscillator saw.
The front part is not much different from other models of grinders, spindle, clamping nuts, stop button.
Perhaps the biggest difference is the two LEDs backlighting, though I doubt they can really help.
Lower part of the locking mechanism and nut.Lower part, on which disk is mounted, is designed for 22mm tool inner diameter.The clamping nut has the same threads as my Makita mains nut, but there is a little peculiarity with the keyholes, one pair has original key spacing and the other one has a little bigger, for “Makita” key. Otherwise the nuts are absolutely identical, right down to the configuration of the slots.
The case is partially rubberized, in the hand lies confidently, nothing slips, when inserting the battery balancing is normal.
The battery is not very comfortable to handle, because the fixation is not by the button holder, but by the protrusion on the housing itself, ie.е. If this projection is worn out, you have to do something with it.The bottom three terminals for connecting to the battery, usually the tool for Makita batteries has two contacts, but in this case, I did not understand the purpose of the third contact, as angle grinder normally worked even when connected only to the extreme, although the middle is usually derived locking.
Auxiliary display and control elements.At the top of the indicator which shows: Battery icon, roughly shows the level of charge.SPD and AUTO modes.Numeric display, two dashes (stop), rotation animation (work), percentage charge from 0 to 100.Percentage symbol, illuminates while charging level is indicated.There are also temperature sign symbols and presumably anti-jamming symbols, but I haven’t seen them in operation yet.
below two control buttons and additional indication:Button to switch the speed mode, full and automatic, in the second case the speed drops about twice, but when you increase the load electronics automatically turns on full speed, mode is displayed as the first LED near the button, and on the top indicator.The second LED is lit as long as the angle grinder is running.Backlight on button, memory mode available, t.е. if you turn it on, then the light turns on automatically, the right LED indicates its work.
There is also a nuance, if the angle grinder was off for more than 30-60 seconds and then press the light button, the top indicator will display the battery charge as a percentage, if earlier, then the two dashes, as in the staggered stop mode.
I have not the first angle grinder, about 12 years ago, I bought myself a compact chain saw from Makita, I think you can see that it is clearly not used to lie on the shelf, although I periodically clean the dust / dirt.My angle grinder is designed for 115mm discs, although in fact the difference from the 125mm version is only in the diameter of the protective cover, speed and power are exactly the same.
Cordless angle grinder weighs a little less than 1.6 kg, power supply 1.96kg (without cord), t.e difference of about 400 grams.
Next I will digress a bit to describe the different grinders.To begin with, I will say that there are two basic types, straight grinder and angle, the most common are angular, commonly called the “grinder”, in the photo it is on the right.
But if the difference between the CMP and angle grinder, I knew perfectly well, then that the angle grinder also have a difference, I did not think.All gave that there is an angle grinder oriented to work in a horizontal and vertical position of the disk, so the observed is originally designed to work in a horizontal position, such as cleaning surfaces. You could assume the use for polishing, but since the speed is not adjustable, this option is not considered.angle grinder where the main position of the disk is vertical, are better suited for work in which it is necessary to cut something.
The position is determined by the ratio of the plane of the disc position, the controls and the grip of the handle.The upper two pictures compare it to my Makita, which is clearly designed for cutting, because in the position where the finger hits the switch, the disk is in the vertical position, and its body is generally universal, so it is easy to use in both positions.The angle grinder in question was clearly designed for a horizontal position of the wheel, so the switch is under your finger and the handle is easier to hold. Certainly it is possible to cut with it but it’s not convenient and you won’t be able to switch it off quickly, you will have to intercept the hand which is an obstacle for safety, the switch should be under your finger.
In addition, a small feature turned out when you install the hood, if you try to cut something, it is not always convenient, the hood can just rest against the surface on which your “something” lies. I put the battery for example.If you are scraping, everything is fine, the hood is set as it should be.
To correct the situation is very simple, it is necessary to replace the screw fixing the hood with a shorter one. Then it will no longer rest on the gearbox mounting screw and the hood can be rotated to a noticeably larger angle. I didn’t have a screw for this, took a bit shorter and put a nut, the required length of the screw should be about 10-12mm, M6 thread.
And as it turned out, the angle grinder under the horizontal arrangement of the disk quite a lot, if not most, for example, the first came across a cordless Makita was the same configuration, the drive is horizontal if the button under your fingers.In some models you can simply turn the gearbox by 90 degrees, but because of the design of the housing, you can not do so in the reviewed model.
Gearbox disassembled easily, even somehow not tightened too much, I then tightened the screws more.
Then I unscrewed the screws and separated the halves of the housing, I can say at once, unless absolutely necessary, it is better not to do this, to collect then very inconvenient. i noticed that one of the self screws fixing the case is longer than others, be careful, in the photo they are placed according to the holes.
The motor is brushless, as promised.
The windings are wound with pretty thick wire, the rear bearing sits in the plastic part of the housing.2. The button looks closed, there is even a rubber cap, but it does not lock, a latch on the housing is responsible for all this.3, 4. The indicator is inserted in the slots in the case and the LED backlight is also on this board
Next to the terminal block is the power section, but the board is almost completely encapsulated.
Judging by the number of wires, this board handles almost everything, both power and control. There are also LEDs and buttons.In the power unit six transistors LNC04R050 installed on a decent-sized radiator.
The front of the motor also has a bearing, and there is a rubber ring that makes it very difficult to remove the front. In addition, the motor is in fact a case-less motor, i.e.е. without the front part it will not work, because it is actually part of the motor.
At the beginning I had no compatible battery, so the tests were carried out with the battery from Milwaukee, it was inserted so that the minus contact was connected normally and the plus was connected with a wire.
And the first thing I checked was the backlight. As expected, it works, but it shines anywhere but. However, it can still help, because it does not turn off immediately, but about half a minute later, which is really handy.
When measuring current consumption I noticed an interesting thing: if in high speed mode it depends on supply voltage, then in low speed mode, it is stabilized. Accordingly, as the input voltage decreases, in one case the current decreases, and in the other case it increases.Below you can see the current consumption as a function of the input voltage, at the top for low speed, at the bottom for high speed, you can also see that the power at the top is stable.
The discharge trip occurs at about 13.8 volts, but the protection works with a delay, t.е. If the voltage drops to 13 volts and then goes up to 14 volts and above, it will work until it drops to the above limit. Given that the battery is 5S, the output is about 2.75 volts per cell, quite normal.After the protection trips the backlight blinks for a while, which is also very reminiscent of Milwaukee.
While playing with the definition of the threshold, I noticed that if the shutdown was due to overdischarge, the braking is smooth, but if right on the move with the button on the power supply to turn off the output, it brakes instantly.
A little bonus in the form of a micro review of the Makita battery case.
Since I don’t own any cordless tools with a Makita battery, I had to order the battery case separately and assemble it myself, especially since I plan to expand my tool fleet a bit. Of course, you could buy a battery off-line, but it’s more expensive and not really sporty 🙂 In general, as soon as was ordered angle grinder, ordered and the case for the battery, it came a little later, so there were experiments with the battery from Milwaukee. I will show you briefly, but if there is interest, perhaps I will write a more detailed review.
Included everything you need in the kit, right down to the stickers.
Inside is a cassette for ten 5S2P cells
And the cassette is implemented very correctly, there is both the distance between the cells, and the protection of the plus pins.Three kinds of contact plates, plus, minus and connection plates, whereby the connection plates are identical. The quality is A, everything is assembled very well and secured by the joints on the body and very carefully, you can not assemble wrong.
The board is supposedly a new version, from 2020. Temperature sensor against battery overheating during operation and a separate thermal fuse for protection during charging.
I have been thinking a lot about where to install the fuse, but nothing better than to put it in a rectangular hole in the cassette.
For the battery I used VTC6 cells bought at Ncon. Just in case, when assembling the battery first install the batteries, then screw the cassette (middle self-tapping screws) and only then are the plates welded!Self-tapping screws are for hexagonal star, not Phillips, also keep this in mind.
The cells had about the same charge as were from one batch, so the balancing was simplified. First I charged the whole assembly to 21 volts while the current well dropped to 1-1.5A, then I recharged the battery in batches until it was fully charged.To avoid screwing up, I first “bumped” the contacts and checked that at least the charge level indicator started.
After that, I soldered them thoroughly. And then gathered everything together, put stickers and for fun weighed the battery weighed 628 grams. Given the difference in weight of the reviewed and the mains in 400 grams it turns out that with the battery installed, the battery is only 200-250 grams heavier.
Now we can do the field test.
I have just left after the repair at least one drive with 125mm diameter, for example on the right Makita disk 115mm, which was once included in my angle grinder, it certainly is old, but it works.
The experiments were carried out with steel mounting strip 35×1.2mm and the shank of a 13mm diameter winner’s drill bit, new disc, 125mm, thickness 1.2mm, the test subjects were attached to a large piece of 50mm board.I would have checked more, but because of the limited space, it was extremely inconvenient to cut.
The first was a steel strip, a little carried away and imperceptibly cut six pieces, on the picture while cutting two pieces, judging by the timing it took 10 seconds.
With the drill shank it was a little longer, about 11 seconds per cut.
I ended up with a small pile of scraps. It would probably be a good idea to measure the RPM, but I can say subjectively that compared to the mains they are lower by about 10%. During the cutting process the speed dropped a little, but this is exactly how an angle grinder behaves.
The claimed power at this angle grinder is 800W, to measure the actual consumption is difficult, because I did a little different experiment, powered it from an adjustable PSU with an output current up to 22A, voltage put up 20 volts.As it turned out, the 440W could give her not enough power, so I had to apply less force when cutting the voltage did not drop. Accordingly the cutting time almost doubled. The real power during the experiments with battery power I think was not less than 600W.
Also of course the question about the autonomous power reserve of such a tool worries. Before I started, I fully charged the battery, then cut 6 pieces of strip and four pieces of the drill shank, but one piece was cut with power from the PSU (there by the way it turned out 0.1Ah).After that the battery was fully charged again and it took 0.45 Ah in my opinion, very economical. Of course as it discharges the RPM will go down and it won’t be as economical but it’s still not bad.
In the end I decided to compare “face to face” the reviewed angle grinder with tool Milwaukee, and indeed, the color scheme, and the overall appearance is very similar, if they would make it for a battery Milwaukee, it would be super, though in principle no one prevents to make any adapter-insert.
Of course it would be nice to write the conclusions after at least a month of operation, and in the loaded mode, not occasional, but so far I do not have such an opportunity.At the moment I can say that the “angle grinder” works and does quite well, I expected results much worse.In terms of power it is comparable to my mains, maybe a little weaker, but probably within the margin of error. There is a function of economy of charge, when the revolutions automatically rise when a load appears, I tried it, it was quite convenient, though I initially thought that during the speed shifting would jerk.The grip is different from my Makita, but I would not say that this interferes with the work, although a slight difference is felt.As expected, the backlight shines where it’s convenient, not me.
In short, it cuts well, no worse than a similar-sized mains, energy efficient, the only question is how long it will last.
I ended up with an angle grinder from bangguda, with the design of a Milwaukee, Makita batteries the body of which was bought on taobao, the cells on nkon. This is how we live 🙂
