Great video with an excellent breakdown of the different components!

Thanks! I was searching for the reading between ground and thermistor as I don't have a pack to test. Now I'm good to go. Very helpful for modification . Thanks again!

Very nicely done Shadowz. I look forward to seeing many more😍😀 I think you did incredible for your 1st video. I've never even thought about taking one of these apart. Thanks for sharing your talent and video, Rodney

Nice video, good explanation. You're better than AvE and no foul language. 👍

Very interesting and informative video, thank you.

That was awesome for first video. Hope you have more video's!

Excellent, I repeat EXCELLENT vid. I was looking for days for a vid that explained fully the Milwaukee M12 battery. I guess KZfaq’s algorithm jumps your channel. I had 2 old M12’s in a case of a tool I haven’t used in years. After making all the checks you described and all checked out the batteries still wouldn’t charge. I then charged the batteries with a NOCO 2 charger. Walahhh! They now charge. It should be noted that the charger recognizes both under and over voltage and won’t charge if either presents itself. Keep up the good work. Oh.....your vid sound quality on this vid could be better.

Thanks for taking the time to share this video.

Big help, I fixed my battery thanks to this! Thank you

Great vid! I love it! That's what I'm talking about! Can't wait for more content!

Good first vid there Shadow. I liked your idea of taking a blown up pic of the battery connections and pointing out what you were testing. It made it so much easier to follow along. Were you using a smart phone for the vid, and how did you get that overhead shot if I may ask? I'm re-shooting my shop tour then try and figure out how to upload it properly, lol. Thanks for sharing. Cheers mate.

Great information on this battery. Well put together presentation.

good info

You could have shown how to replace a bad cell but the testing part was great.

Good video. I'm into taking things apart as well. I'm a scrapper (metal recycling) I go out on my bike but I think you'd be amazed at the amounts of cable I bring back. Started Youtubing recently as well and I know every subscriber counts- liked and subbed.

I have 1.5 Amp battery and I want to buy 3 amp battery to replace 1.5 ones.Is it possible to use 1.5 amp battery control board for 3 amp batteries ?

Well done! Thank you

Is it possible to take one of those apart and solder a 12v cigarette lead to it to make a m12 air compressor corded for extended use

Thx for the video. I have a M12 compressor in my car, but I don't always carry M12 batteries. I'm trying to rig up 12v cigarette plug for emergencies. I can get spade terminals on the pos+ and neg- terminals of the compressor fine, but do you know how I can mimic the Temp "T" connection?

Do the non compact 12.0 (3.0,4.0,6.0) batteries contain some sort of intelligence, or rather for that matter, whats in the base of those?

Hi. Suppose i want to balance charge one of the cell can i do it directly from the top pins without opening up the casing?

Nice job making this video

I have a couple 4 and 6ah milwaukee m12's and one of my 4ah decided to unbalance the crap out of a cell and wouldnt charge in 2 different chargers. it was flat (i mainly use it with the m12 soldering iron that chews up battery power for sure), Cell cluster 1 and 2 were both reading around 3.8v but cell cluster 3 was down to about 2.8v....... Any ideas how it became so unbalanced? I use a milwaukee m12/m18 fast charger, is it the charger? (i also have a standard m12 only charger lying around i could use instead, charge time doesn't really bother me, i've got enough packs), do the fast chargers potentially cause unbalance's in cells due to ....fast charging? I thought maybe bad cells but what are the chances multiple cells in that "cluster" on pole 3 going bad (as opposed to a single cell in that cluster dragging it down). Non the less, too fix it i used my fancy RC Helicopter IMax X400 battery charger, split the pack open (stupid simple for those bigger packs too, 4 screws and its done), attached it to the individual cell cluster that was down, selected Li-ion mode/single cell mode and bumped the voltage of that 1 cluster up to 3.8v also. Then hooked them up to the balance lead port and balanced all 3 cell clusters up to a bit under 4.08v, put back together and let the milwuakee charger finish it off. Will keep an eye on the pack over the coming week and see if that cell unbalances its self again

Hi, How do you clean the terminals? Can I spray contact cleaner into the terminals or will this short out the battery ?

Would you consider taking apart a cheapo knock off battery for m12? The cost delta is so much I just have to try one for those batteries for low draw items like a screwdriver.

Great video!

Shadowz! Great video!

Awesome video!! 👍

good video Daniel

밀워키 좋아 굿👍

cool video I have loads of the batterys

Searching for this battery I can't tell if it got the seamless case with a screw in the bottom or the clipped version where you have to brake the clips. Is there any chance to identify those different case Versions. Because of the high premium costs I want to upgrade them with some Sony US18650VTC6 for better performance by my own.

Thanks for this video. I have tried to unscrew that screw with a t10 but it won't badge. I have sprayed w40 but still no success. Any ideas?

Could you open up on new Milwaukee m12 3.0ah and find out what kind of power they're pushing

You obviously missed where they hid the gold, which is why they cost so much 😋

be nice to your Note9 pen :-)

is it safe to open a battery without discharging it?

someone needs to do a teardown of the usb single cell batteries. can they be rebuilt or opened? would love to swap out the 2.5ah cells with something larger.

I saved this..Great info!! keep these videos coming. I found you through Miss Canadian Scrapper. I have subbed and rang the wee bell too. Hope ye might check my little growing channelas well. Be sure and leave a comment good or bad..lol. Fair Winds and Smiles!!!

Can you fix schematics for M12 6 Ah battery, the one I have found at sellers site seems to be wrong? i.ebayimg.com/images/g/-OUAAOSwERdgSZW~/s-l1600.jpg kzfaq.info/get/bejne/idCjl8KQ2rGboI0.html
