So the factory code I might be able to shed an idea on. I work in a field that had a recall on a particular product and they had what seemed like a random number. In that numerical digit to find out if it was in the affected batch they'd isolated it down to a certain date code range. The digits all meant something. If my theory is applicable to your scenario every battery you test one of those digits will always be a 1, 2 or 3 signifying 1st, 2nd, or 3rd shift. One example given was 221111. That date code was done in 2022, the 11th week, day one of that week, on the 1st shift. Between the info on the battery it might be more specific information like what shift or plant it came out of. Neat video.

maybe the 3rd light in the first set is to indicate if it's out of range on thermal from the battery getting too hot? and id defiantly agree with the 4th set being some sort of revision/firmware, batch, or maybe QC# so if there's a recalled batch tied to a certain inspector they can tie the battery to them based off the 4th code, the days since first charged and the date code on the battery's label

When I first switched from dewalt to the m18 was back in the early days of the lithium ion. The Milwaukee rep had a thing he slid on top of the battery that would tell you how many times the battery had been charged. They also claimed 2000 charges guaranteed. Mine made it halfway through a hot summer and couldn’t keep up like the old Dewalt, so I ended putting all my Milwaukee tools on the shelf. The owner of the construction company would pay to get us the DeWalt batteries and not the Milwaukee ones so I never switched back. Now I no longer work in the trades and don’t use them daily so I have switched to the m-12 system. If its not enough power I just use a corded tool. Have all of those because it was the only way to do work back then. You got me cautious if my dusty old first generation tools still, work. The sawzall was amazing

@starseeddeluxe Ай бұрын

I used Milwaukee tools daily for 10 years now, all the different models. If you're someone who wants the best tools, Flex makes the best 7 1/4" right blade circular saw, and 6 1/2" worm drive cordless circular saws, with their 24 volt batteries. I made a video showing why Milwaukee M18 circular saws are really not suitable for people who do precision woodworking. The Flex saws are quieter, have more battery capacity for the money, their big saw comes with a stacked lithium battery, but more importantly, they actually cut straight. I tried two M18 saws, both were misaligned and non-adjustable. And Dewalt makes the best impact wrench, the DCF891, it's the most powerful cordless 1/2" impact wrench in the category. Milwaukee has the best 1/4" impact hex driver, called the "Surge" hydraulic drive model, it's absolutely silent. Bear in mind, Milwaukee tools fail quickly in high humidity, high moisture, cold climates, I've had at least 5 failures due to moisture.

@scottpollock1714 26 күн бұрын

@@starseeddeluxe i work in the trades as well, ive used dewalt and milwaukee primarily (milwaukee now) however a bunch of my tools were stolen from a worksite a couple years ago (right around when flex was getting known) and i decided to give them a shot and rebuild my arsenal with flex -- worst decision i couldve made. Yes their tools are super powerful, but thats because they dont superbly regulate the draw that they take from batteries (my understanding of it anyways as a layman) and as a result they overheat to all hell when your doing any amount of extended work (ie rebuilding a deck - driving screws, cutting boards etc.) and as a result the batteries also die way prematurely, only 1 (of 8 various capacity) battery held up after about 8 months of use. And agian while its more of a minor gripe the heat that they do put out when they are overheating makes them unpleasant to use. Maybe since i used them they have improved idk, but im never touching one again. I love my surge too, the noise reduction is an absolute godsend when working indoors in smaller spaces and just in general. Have had a number of other tradies onsite marvel at it.

Milwaukee batteries drain while sitting on the shelf not being used. I lost 7 or 8 all at one time. I talked to our local rep he thought it was a bad charger but they were all being charged on different chargers. After he and I did some research. If you store a dead Milwaukee battery in a cold garage once they completely drain, they will not charge again.

@whitechris720 9 күн бұрын

@starseeddeluxe I think makita makes the best battery-operated saws! I have the regular skill saw, the worm drive and the 36v miter saw. I have been running the same saws for several years almost everyday. I had one issue with the miter saw the local repair shop couldn't fix it and sent it too Japan. It was repaired free even though it was past the warranty date. Now it's been about another year and it runs like a champ! I have had several older carpenters question is abilities. I let them run it and test it. Everyone has said it is the most accurate table saw they have ever used.

Not surprised... very easy to tell for warranty... as they have a date (2 year) and charges (2000) warranty, so they watch for those 2 numbers... and if the battery tracks it, makes it easy to go yes/no for free replacement (1 year & under 1k charges) or pro-rated replacement (1-2 years, 1k-2k charges).

So helpful, thank you. Just tested on two of my old m18 2.0Ah batts (approx. 9.5yrs old / 3462 & 3450 days respectively), which are still going strong. To my amazement they’ve only been charged 63 & 36 times! I thought they must be ready to give up their ghost. / A few comments made about binary patterns (128, 256, etc), but this might be coincidental as the 4th data point for my batts, which came from a kit and extremely likely the same factory, both have “2186”. Incidentally, they both had a value of 0001 for the first data point, whereby they had a charge of 2 bars and 3 bars.

@toolscientist Ай бұрын

Do you have a more precise manufacture date on those? It should be on the heat stamp near the terminals. Your date of first charge is October 2014 and April 2014 is roughly when batteries show 0001 instead of 0101.

@5amonline699 Ай бұрын

No precise date on batts I’m afraid AFAICS. All my M18 tools have a “Code” followed by 19+ digits, whereby I can see the last section is the year of manufacture. For example, the M18FPD and M18CID drills I bought in kit form with the above batteries have “D2013” and “G2015”. My most recent M18 tool purchase has “H2021”. However, both batteries only have “4932 4300 62”, which I believe is the “Code”. Next lines are: “5 INR 18/65” / “M18B2/2.0Ah” /36Wh” / “18V ~ Li-ion” / “Ser.-Nr.:34109” (“Ser.-Nr.:38048”) /

Yeah lots are reporting uncharged batteries have the 3rd light lit.

@ToolsAndStuffOFFICIAL Ай бұрын

Could you please do us a favour and NOT put this battery on a tool. Can you please put it on the charger once and wait for it to start charging, then remove it and test the numbers again? Thanks.

I have a 5.0 aH battery that has been charged for awhile with the indicator light on the charger displaying GREEN. However, when I press the button, the first light flashes 7 times (VERY QUICKLY) and the others do not illuminate. Thoughts????? I have numerous Milwaukee products but quite frankly, I am starting to get frustrated with their batteries! My oldest ones are 3 years old and most recent ones are 6 months old. I have experienced issued with a few of them. Help!!!!!

I have a 5AH that on the first set it is 0011 and not 0101 and the next 2 sets have nothing recorded/tracked in them 4 set is 256. This battery was purchased over 1yr ago and to this day has not been put on a changer yet as it has not been needed.

@voldemortified 17 күн бұрын

I wonder if any of the numbers could be the voltage - not of the whole pack, as that’s easy to test directly, and none of the numbers seem to match up for that - but perhaps of the individual cells, or perhaps the weakest and strongest individual cell? Not sure, but I feel that would be useful information for it to report. Factory codes make sense at first glance - but thinking about it (I’m a software engineer, and this is how I would do it), it seems so much easier for them to simply maintain a database of serial numbers, and have an entry indicating where each individual battery was made (and so much more about it). Or, like VIN numbers, there could even be a specific digit in the serial no., that’s the factory code…

I think the third one would be if the battery had ever been overheated or overcharged or abused somehow on the charger by overcharging or something causing it to overheat that would be on most likely I think that's what it is I don't know it's just a guess but that's what came to mind

@toolscientist 2 ай бұрын

Can you post exact date code, battery type, and the codes. Also the first 8 digits of serial number (something like J51ADCHB). This will help us figure out when the batteries got their codes back and what trh 4th code means

@ToolsAndStuffOFFICIAL 2 ай бұрын

What is the date code from the battery?

@southaussiegarbo2054 2 ай бұрын

@toolscientist could that last code be related to the cells inside batch code or something? Considering they often buy a ton of cells and then do multiple battery production runs with that batch?😊

@toolscientist 2 ай бұрын

@southaussiegarbo2054 don't think it's cells. So far 256 covers 1.5Ah, 2Ah, 5Ah, 6Ah HO, and 12Ah. We also have 12Ah with both 256 and 512

@davidwal7344 2 ай бұрын

Just an fyi I just checked my batteries and one of them was slightly used but still had 4 bars. I checked the diagnostics on the battery and on the first set of diagnostic lights it was off,off,on,on not the off,on,off,on the other batteries indicated. It was not overused I just got it a month ago. Not sure why that one was like that. Its an HC6.0.

@ToolsAndStuffOFFICIAL 2 ай бұрын

How many times had it been charged? As we have now found that brand new uncharged ones show 0 0 1 1

@davidwal7344 2 ай бұрын

@ToolsAndStuffOFFICIAL when I first checked it had 0 times on the charger but I put it on the charger to see if it needed a little charge and the charger indicated it was fully charged. It was on the charger once but did not charge. After that it still read off,off,on,on. Maybe it has to actually take a charge to change the status.

@ZiggyTheHamster Ай бұрын

That fourth code being 256 or 512 gives me a tingly feeling. 256 and 512 are successive powers of two. I'm curious if all of them are powers of two. Could this be a bitset of the battery capabilities?

Is it definitely 230820 and not 200823? So far nearly every type has regained their codes by early 2022. Although so far no one has a new 4Ah with codes.

@rbproductions78 2 ай бұрын

@@toolscientist Definitely 230820, I'm in NZ too, I wonder if it's origins have a role to play? Have you figured out what all the other numbers alongside the date code are? Both of my 5.0's that don't have the feature are clearly from the same batch as they have a matching number to the left of the date and the 7 digit number on the right of the date is consecutively one digit different. I'm guessing that the one on the left is factory/batch/machine related whereas the one on the right is unit number from that batch. I also have another 5 batteries at work which I will check and get back to you on. Keep up the good work man, it will bet interesting if Milwaukee have anything to say about it? I assume when a battery is returned for warranty purposes this information is extracted by the service provider so some people have to know what this all is about.

@toolscientist 2 ай бұрын

@@rbproductions78definitely looks like [type & factory] [YYMMDD] [unit number]. The first 8 digits seems to be G29 = 5Ah (B22 = 1.5Ah, E53 = 2Ah, K35 = 3Ah HO, J51 = 6Ah, J52 = 12Ah, etc), [A-Z] maybe revision/batch/line, "DC" always the same, [AE/BA/BB/BC/JA/JC/HB/HC] = factory? Can't see an obvious relation to the 4th number yet. Seems to be some relation, but then there's a battery or 2 that breaks that relationship.

The end number could be associated with batch code

@southaussiegarbo2054 2 ай бұрын

Actually as someone else said it could be related to the circuit board revision number. As they often use same board across all modals just increase cells etc it's a theory that it could be the board batch code... so say circuit board batch was 12032024 and the code was say 324 it is board batch made march 2024... Its a possibility considering i seen it in some other electronic stuff when in school.
