[@Stevesbe]

@Steve D it's does to makita they make more money

[@joshuabest100]

Each cell is 4.2v fully charged so an 18v nominal battery will have 5 cells if you have a bigger battery like a 4ah or a 5ah or bigger it will have 2 pair of cells parraleled to give you more amphours you cant check cells in parallel

[@robertfowler3457]

Holy crap that's expensive, what a great device, so handy to check the status of batteries, not sure why it would be that price!!

Ok, now I got a gripe with you! I always thought you were using batteries like mine to make the test fair. You know, run down to the last electron, been charged 200 times, got chips and dents all over 'cause the apprentice can't catch it when I throw it down to put on the charger and left out in the rain a couple million times... Sheesh! What ever happened to real world testing? Lol

[@timhowell6064]

I think a look at how the cells discharge in each battery of a 18v X2 tool would be neat to look at with this thing.

[@jon_byler]

have you tried this with off brand batteries that are made to work with makita? I think the checker is communicating with the Yellow plug, and it would be interesting to see if any of the clone batteries use the yellow plug to do the star communication system with the tool.

Very neat. Basic Makita chargers do these checks every time you charge one. They just don't have a visual readout like this awesome gadget!

That is such a useful tool. Only I am not on the Makita platform. Could have been and should have been. Went to a tool show intending to buy Makita but the salesman would hardly give me the time of day. His Bosch competitor complete opposite. Ended up spending a lot of money on Bosch and they keep dying. Bosch do a simpler diagnostic battery charger but mine never worked. In fact it corrupted and killed four of my batteries that Bosch begrudgingly had to replace. And a new charger but scared to use that. So thanks to a bad salesman I can only watch your videos of superior tools.

[@tearodman]

this device I knew from my first Makita kit I've bought. One of the batteries came dead, and the repair center where I live tested the batteries on this device. So they RMA the battery and I've received a new one a week later. Good to know how this device works. Guess I'll visit the repair center one of these days with all my batteries, lol. I guess all Makita repair centers have this tester.

[@MrHimer12]

Makita batteries 18V are 5 series 2 pararel cell configuration. It has 10 cells but in paralel to provide more current and also it reduces stress on single cell. They use VTC4/5/6 mostly I have never seen makita battery with other cells than Sony so far. Yes, you can pull 30A from single cell but you can also reduce the current for each cell if you do paralel connection and as a natural bonus you benefit from extended capacity while lowering load on a single cell - battery lives longer.

[@lincolnbarlow4778]

They use Samsung cells these days I've seen it myself

That's an interesting gadget. I have about 6 Makita batteries. The oldest are two 3ah that came with the first kit I bought in 2015 before they started putting the gauges on them. They both still seem to be going strong.

[@GoFastGator]

Another data point that would be nice would be either the total Ah or Wh the pack has been run.

[@donaldbougie694]

You have reason,it,s the Ah or Wh interest me,not the voltage i work in a battery and change the cells in for more Amp and i have the same voltage more energy.

[@zoltanberkes8559]

It shows the cell voltage for only the half of the cells, because cell pairs are connected in parallel.

[@grahamwilliams4417]

I’m actually deep involved in battery testing. I’m going out on a limb to say: nope, it doesn’t work like that. Globally, it depends on how the battery analyzer is built. Most of the modern ones can do serial, parallel, and the various combinations of the serial / parallel used in multi cell construction. The 18v sounds like it’s 5 serial of 2 parallel. The complicating factor is the chip in the battery that most likely is communicating with the Makita analyzer.

[@zoltanberkes8559]

@@grahamwilliams4417 Maybe I was not clear. Just disassemble a battery and you will see: two cells are in parallel and 5 of these are in series. The balancer circuit meassures and controls these 5 pairs, hence it only can provide data of these voltages.

[@ccbowers]

I'll have to remember to look for this in Japan, whenever travel becomes less problematic. I wonder how much it is there, and if it is widely available

[@FearsomeWarrior]

When I do get to travel I ask on Reddit or ask small KZbinrs if I happen to know they’re in the county I’m headed. That way I can kind of get a lead on tools and even order them and sent to them. Usually only after a few annoying to get items.

[@ccbowers]

@@FearsomeWarrior Japan is difficult because of the language barrier and "DIY" seems less common than the US. Even in the US, without these networks, it would be hard to find a knowledgeable person in a given field, and I know the language well. For consumer electronics it's a bit easier because it is part of mainstream culture, but power tools are less so.

[@herbertvonsauerkrautunterh2513]

Sweet as broh.. These batteries don't have individual cell monitoring. So this isn't foolproof. Sometimes only one cell goes bad and you need to disassemble and individually charge and test the cells

I think it would be cool to see the difference in temperature between 18 and 40v on a similar tool. The 5ah 18v can only show 5 cells bucause they are wired in parallel pairs of 2 wich will have always the same voltage. Same for the 5ah 40 v

Very interesting. You never fail to bring all the makita goodies to the masses tools. Thank you very much for these videos.

Well I know what I'm gonna look for next time I'm in Japan ^^ Also regarding parts of the world for the contest, if the UK viewers are more numerous than the rest of Europe then fair enough. But since the UK has left the EU there's a ton of taxes and tolls for the rest of Europe when buying from the UK (so much that a lot of us really don't bother anymore). So if the viewers from the rest of Europe outnumber the UK ones I'd suggest getting the voucher from one of the Amazon branches inside the EU (France, Germany, Spain, Italy, Sweden, of the top of my head), since anyone within the EU can buy from any of those without any tolls or extra taxes. :)

[@jonRboy]

I was curious about this battery checker (BTC04) and decided to call Makita to ask what the deal was with it...why so expensive, why so 'rare'. The Makita rep found the part# but said it was not meant for endusers/customers. This device is meant for Makita Service Centers. So that's why it's so expensive and kind of hard to get. I'd love to get one but not interested in spending $250 to get one. It's too bad that Makita doesn't make it available for customers, but I can kind of see why they'd probably think it would perhaps open a 'can of worms'.

[@ToolsAndStuffOFFICIAL]

It is available for anyone to purchase in Japan. And lots of other regions sell them direct to customers. I'm guessing you are in the US,?

[@jonRboy]

@@ToolsAndStuffOFFICIAL Yes. I’m in the U.S.. Thanks for the info. I guess the entire issue is a bit murky because with online commerce, individual national sales policies are moot. So, I guess we’re talking about purchasing in a ‘physical’ store, and Makita’s policy for U.S. as I said is a ‘NO’ for sales of this to tool users. In the U.S., Makita tools are sold at hardware stores, lumber yards, Home Depot, etc.. So, what you appear to be saying that if other countries had physical stores and/or outlets like these that sell Makita Tools, that the BTC04 would be a regular item to purchase just like a drill, router, or saw.

BTC06 For 12V CXT. Hefty. Pretty cool though. Parallel-stacked battery packs shows single bar per cell as there is no measurable difference on parallel circuits voltage.

I would love to see the cycle counter on bunch of my 1.5Ah batteries. Been using them for 5ish years now doing Ikea and other flatpack assembly. I tend to charge each one about once or twice a week so guessing about 250-300 cycles. They are all still going strong though. They are great for the subcompact drill and impact

[@subodai85]

was gonna say immediately with that adapter, it's only got basic DC connections. You need to have a full connection to the cells individually and chip with all the extra connections. A bit like how you balance charge a LiPo. Ah, looks like covered that with the number of pins.

[@patrickderegt2582]

I first saw one of these yesterday, at a Makita service center. and I would be vary interested in knowing what counts as a charge because when I was at the Makita service center I was told they normally wave the 2 year warranty and as long as a battery has not been abused and is under 200 charges. they will replace it.

[@hermitette]

I remember stumbling across a video of a guy playing with one of these years ago in a foreign language, went on a googling mission and couldn't find anything about it.

[@CheapHomeTech]

This appears to merely read the battery metrics Makita stores inside of it. I was hoping it also did a capacity check. Where it can drain the battery as if it were in actual use and display the results. So I can tell if the 6Ah battery I bought off Amazon is really a .5Ah battery. The batteries bought off Amazon all seem to weigh less and go dead quickly.

[@noureddinedaira]

Thank you for the video, very useful. It is available from Spain in Amazon EU for 250 euros. The prices in Yahoo Japan are just crazy.

[@semidemiurge]

I contacted the Makita Service Center in Denver as I have dozens of Makita tools and have ordered parts from them over the years and they are quite knowledgeable and helpful. They have no knowledge of this battery checker and the part number is not recognized in the MakitaUSA database. It would likely be a different part number here as the BTC04/5 is likely for Japan and/or Asia. Each country's Makita Corp. is operated as a completely separate entity. We are just getting 40v units in now and he thought it was likely a new device and might become available in the USA eventually. If I had the time I would pull out my o-scope and do an analysis of the serial communication between the battery and the charger and likely could extract this data and cobble together a similar device.

[@ToolsAndStuffOFFICIAL]

The BTC04 has been out for a long time and uses the same number worldwide, including America.

[@MikadoRC]

Yeah it would be super interesting what kind of data is exchanged over this bus connection. Also if the normal battery charger recieves the same amount of information. There should be a temperature readout of some sort on the 18v batteries for the charger

[@minispud]

I'm curious if the 40V batteries are cutting out with some juice left in the tank because at the higher temperatures they get derated otherwise they get really damaged. But 75C is way higher than lithium batteries want to be (typically you only want to charge them if they're between 0 and 35/40C)

[@clam741]

I can speak of heat numbers but Makita chargers won’t start charging if the battery is too hot

[@insiderepublic8066]

Try charging the battery 50% and se if the charges number go up. On sites it happens a lot to take the battery from the charger when is 50-75% charged, but this is not a full charge, and if it counts it as craged then it might not be extremely accurate 🤔

[@engdarfatgalalyelectrical1076]

Your work is beautiful and useful, I hope I am healthy and safe

[@alexteixeira27]

Battery charges cycles counts when 0 to 100. Best case scenario for example this battery has 3 cycles and it 23% charged, I put in the charger to 100% it not going to show 4 cycles after because I haven't completed the 100% cycles yet. After depleting and charging it pass 23% I now have completed the 100% cycles, it really hard to explain. Also battery health degrades overtime when stored even if you don't use em. Fully charged battery stored degrades faster. For storage of lithium ion battery is 35% to 40%. If you notice certain devices you buy comes with around 40% charged that to protect the battery if the device stays on the shelf long time. Some devices now especially on Amazon comes fully charged because these devices sell quickly. There a lot more about lithium ion battery

[@e9999qwe]

Neat, but it's disappointing that it did not sound like it could do an actual full discharge test with a load, which is really the only way to know the health/capacity of the battery accurately. The indicators of battery life shown in the vid are likely just snapshots and extrapolation, but unless the battery circuitry actually measures real discharge numbers and memorize them, and the tester can read that, it's hard for me to believe that the shown indicators are very accurate. Still, on a relative basis quite helpful for a quick check. And could be quite helpful if you sell battery frequently, as buyers might be reassured of the battery health, which may save you some money. (for instance I don't buy used batteries cuz I can't tell how good they are and people lie too much.)

[@frankv84]

Here in NL they're easily available, for around €250. I'd expect similar in other European countries. Got me one after watching this video, and tested most of my 18V batteries so far. I have had my 2x18V chainsaw cutting out with blinking battery indicators several times and then usually I push on as soon as I can, causing some serious temperatures in the batteries. So I expected some of them to report some overload/overheat count, but all of them reported perfectly healthy. I guess the protection in the battery/tools does its job. Still need to test my 14.4V batteries, which are a bit older. Interested to see how those have held up.

[@614southside]

To maintain perfect battery conditions is almost impossible in rl, batteries need to charge at the same time and and discharge at the same time, the battery cutting off instead of slowing down little by little is a sign of a great battery, when your battery hits different levels from fast to slow to off is a sign of a junk battery, perfect batteries that have been double computer matched will charge and discharge at the same time, giving maximum power all the way till it suddenly stops without changing speeds,because all 10 cells are in perfect unison and also they have the exact same storing capacity. in my almost 30yrs in the field as a finish carpenter, no battery will outlast a Big Mak battery year after year, I think it’d be an awesome test to get an adapter for the other big brands so you could do side by side tests then show the batteries and what batteries are the slowest to demise over multiple charges, my guess is Mak will be at least double as good as the second best battery. But I’m just guessing lol anyways great video.cheers🍻

I mean on the bright side, I have a huge supply of cell's for other projects. On the piss me off side, I haven't pulled a single bad cell out of a "Dead according to the charger" makita battery yet.

[@spencereagle1118]

I've got three Makita 3.0ah batteries from 2010 (I always write purchase dates on them) and they are all going strong. I'd love to check them on this tester.

[@OmegaGamingNetwork]

@@spencereagle1118 Yea the vast majority of my makita batteries last for years. It just annoys me when one declares itself "dead" and I pull it apart and the individual cells all test out perfectly fine.

[@danijel124]

I have a question. Do makita batteries have a undervoltage protection built in the battery? Because i would like to use the batteries with other stuff which wasnt intended for

[@whitechris720]

Can it fix anything or does it just tell you if there is a problem?

[@hayden3488]

Just wondering how you buy things from Amazon USA . Tried but says won't send to Australia. How do you work around this to get tools?

[@ToolsAndStuffOFFICIAL]

They only ship certain tools down-under. I don't buy many tools from Amazon. But I have noticed some brands are easier to get than others. i.e. it is much easier to get Milwaukee and Metabo HPT stuff than Makita.

[@hayden3488]

@@ToolsAndStuffOFFICIAL Yeah, trying to get the new 36v Metabo htp nailer and the new 18 guage Metabo htp bradder. Can you suggest any other way of getting these? Hikoki Australia isn't expecting stock of the bradder til April next year🤯.

[@user-fo2vr5qz2l]

@@hayden3488 hm, won't ebay ship stuff to your country, either? Amazon doesn't ship stuff to my country,too)) (russia)

Hi there ..i am in NZ but i cant find this battery checker anywhere on internet . And i cant see your link

[@GRamerDim]

would it work with different brand of battery with a 3rd party custom adapter? and why is the 40v xgt so pricey, does it have a chip/control board in it?

[@mediumgrey8674]

I dont think Vince does much Makita or technical content. Mostly power tests and loudness.

[@diy_Lab]

Thank you for great review 👌 I am relay impressed what this small device can do . Unfortunately for me it’s is to price 😞.

[@Ist_Geheim]

I didn't know a makita battery checker exists. I'd buy one for the price of a charger, but unfortunately it's way too expensive.

[@frankbunce]

SES Direct in Invercargill sell these on their website for NZ$300. They said Makita NZ have a few left in stock.

[@jagenaught]

Still waiting for the electronic clutch tests between Makita, Dewalt and Milawaukee combi drills.

[@setheverhart]

Great find.

[@whitechris720]

193681-8 Refreshing Adapter, ADP03 This one says it can fix issues?

[@TheScouseMonkey]

regarding battery bars, all the 18V should show 5 and all the 40V should show 10 as the larger capacity batteries are wired in parallel and as they are hard wired the BMS cannot tell the difference between any cells in parallel and treats them as one cell. e.g. a 40V 2.5Ah battery has 10 cells all in series (10x3.7V = 37V nominal but charges to >40V), a 40V 5Ah has 10 series sets of 2 cells in parallel. The BMS will see each parallel pair as one 5Ah cell as they will always have the same voltage as they are hard wired + to + and - to -.

[@TheScouseMonkey]

also you have to consider which are 21700 and which at 18650 when comparing which have just 5 or 10 series high cap cells vs 5 or 10 series sets of parallel cells which will mess up the above a bit, so maybe an 18V 2.5Ah vs 5.0Ah would be a better comparison as they should all be 18650 cells. Tool manufacturers normally play it safe and use lower capacity cells that are nice and robust vs the latest and greatest, e.g they will use 2500mAh 18650 rather than 3500mAh which will be more fragile and more £.

[@robertrada4783]

I saw that Hilti had one of these end user diagnostic tools. But this is way more comprehensive. I like it. 👍 Post watch link click edit: Yeah, let’s not pay $800 for something with about a $250 msrp. 😂

[@troyblack1882]

Depending on where in NZ your located the next time I’m over I’ll bring a couple of batteries that have been heavily flogged for the past 8+ years and some that flash as broken on the charger aswell to see what they come up as

[@krcarpentry2610]

I had 8 the past half year and charged them all about 60 times each

[@aryluiz]

Awesome video, well ✔

[@ToolsAndStuffOFFICIAL]

Thank you! Cheers!

[@Dave-dh7rt]

I wish i had a 18>40v adaptor for charging my 40V battery on an 18V charger!!! The XGT chargers are damn expensive

[@ToolsAndStuffOFFICIAL]

But if you buy a 40 volt one you can get an adaptor that charges 18 volt batteries and sell your 18-volt charger 😉

[@aristo188]

at 600-700 a pop but cant seem to show individual cell voltages? only parallel readings.

[@elgi131]

How many recharge cycles do these batteries hold up, before you'd have to buy a replacement?

[@majl1000]

I would be very interested how the coffee maker effects batteries 👍

[@kieranomahony00]

Excellent video. I'm curious, what kind of readings would you get if you refurbished an old dead makita battery with new 18650 cells. And if so, is there a way of resetting the number of charges to make it count from 0 on fresh cells?

[@ToolsAndStuffOFFICIAL]

You can buy new chipsets for the batteries which will be set to zero

[@ToolsAndStuffOFFICIAL]

And thanks for being subscribed for 4 years!

[@kieranomahony00]

Ahh ok, it's good to know that's an option then. I should try to get one of these, it would be so helpful. I didnt know you could see how long I've been subscribed 😅 That's pretty cool, I love watching your tool review videos when I get time. They're great, thanks for your content. Keep it coming please 😁

[@ToolsAndStuffOFFICIAL]

Plenty more coming...

[@user-fo2vr5qz2l]

The Broken makita battery won't work after setting new cells unfortunately. It's impossible to reset it) Oh 4years. I've found this channel by chance only thanks to makita came up with their new line xgt)

[@iangregoryhome]

Nice, would you know if any other brands do one?

[@joshhallstrom6962]

Very cool find, how do you get new firmware for it for the SD card?
