M12 6ah Vs The Knock Off 

Glad to see some proper battery testing with a standardized load!

Great review. The knock-offs are tempting. My concern is fire hazard. I always end up getting OEM batteries and have never been disappointed or set ablaze. Thanks for taking time to post this!

Oh wow, that FUTUREBATT WK12 looks like a quality knockoff(lol) battery! I think I'll get it for an extended run pack -since Milwaukee was too cheap to do anything better than 1.5Ah packs in my starter kit.-

In my experience for regular use for household tasks with milwaukee tools duch as M12 drill/driver combo, the m12 tire inflator the battery works fine. They also work fine as a battery bank with the m12 usb adaptor tool for charging up phones and other batteries and usb battery lights in the house just fine. My preference today are the Waitley branded batteries. I think more interesting tests to see today is how well the internal pcbs work to balance cells conpared to active and passive cell balancers available on the market today. Would be surprised to see some interesting results how to keep your cheaper batteries last longer than the milwaukee batteries.

I have about a dozen Waitley 9.0ah M12 batteries that I used at work working on cars full time Technician. I even use the M12 battery adapter so I can use it to power my Evap Smoke Machine with a single Waitley 9.0ah M12 battery. Use it to power my Kayak Brushless motor, Paddle Board Fin Brushless motor, Watersnake T24 trolling motor. Only had one fail in the last 3 years. They are so cheap in price, just buy a new one when it fails 2-3 years later.

I have a lot of m12 tools but I m not very hard on my tools I’m just a diy. I find for my needs that the generic batteries are fine. I use them in my hammer drill and my m12 air pump and my m12 vacuum all the time and they work great at a much lower cost.

I have a Milwaukee band saw that is very small which I use for simply cutting through heavier wire when I'm doing a panel change out. I had two 12 volt batteries, and one of them had just died on me, so I went ahead and got two of the cheaper no name brand off of eBay, and they fit rather nicely in they seem to work decently. The way I figure it, I can always have something charged while I'm cutting some things, and I can charge the other items while I'm working. Generally the way that I'm using it, I will have plenty of time to charge two batteries before one of them dies. Thanks for the great video! may Jesus greatly bless you!

💪🏻🕵🏻‍♂️😎😎 Thanks for the video!

I'd like to see the waitley 9.0ah m12 knockoff tested vs a 6.0ah or a new high output 5.0ah..thanks, good info👍

Thanks, I have bought 2 pack of batteries 3 times. I'm a home owner had a big project going. 2 times 1 of the batteries were a dud brand new. Then like a year later the other battery went out. I store them in my warm house fully charged when they work. I have 1 battery out of six.

I have the cheapo generic and have been pleased, if i need high power or long run time I have m18 for that

I've been using them at work since genuine batteries have an unfortunate tendency to grow legs and walk away. The connection kinda sucks if you're using it on a tool like a plunge cutter. But i mainly run lights off them. Have enough on hand to run my lights well over 48 hours straight. Cheap enough that you don't care if it falls 150 feet down an elevator shaft. Not great for tools with high amp draw. But for lights and other low draw, low manipulation tools it's a very worthwhile option.

I purchased a 9.0 m12 knock off from eBay after it discharged completely it didn’t wanted to charge any more I tried jump starting it and neither worked .

Can't think of a more fitting tool to take apart another

I built my own knockoffs using generic cases and better quality cells than Mikwaukee. A CP 2.0 that hits harder than the XC 6.0 and a 9 cell 8.0 that is rated at 105A, it never gets hot and never 'sags'. Finally my M12 stuff is performing the way I want!

You look really familiar, did you have a different RU-vid channel before? I appreciate all your great videos.

Great video, thanks! As a contractor myself, I actually use generic m12 batteries with great results. I find myself even preferring my generics over my name brand m12 batteries sometimes. They’re very hit or miss, though, and maybe have used cells in them. I have had one fail that I got refunded for, a wire needed re-soldering. Additionally, on some of mine the clips seem to be more brittle and break easily vs the milwaukees.

wonder if anyone makes an m12 battery with the 35 amp discharge sony vct5a cells?

The knockoffs I have (I think they’re Vanon) are great for me. I bought mine at goodwill for $3 a piece. I do hvac and they haven’t let me down 🤷🏽‍♂️

I'd like to see the craftsman v20 ones!

Next time you do the wiggle test have the drill trigger pressed. Thats when my throw a error code. It disconnects with most of the generic m12s I have. Some wont charge when new. The wailteys worked great on my makita v18 tools. No problems there but the m12 batteries have fit issues. I stipped buying them. The genuine milwakee batteries are half price on amazon. I prefer those.😊😊😊

I'm looking for a tool to use driving screws on metal roofing that I plan to install.....any recommendations out there?

I have three of the cheap knockoff batteries only for my m12 tire inflator, flash light and m12 radio, they work great for no load tools, bought 3 batteries from eBay for $20 but when using them in the ratchet or drill they suck.

The main issue with knockoff batteries is not just the fake rated capacity, but the very low discharge capacity they have. If you use them in a tool that requires a high discharge rate from the battery, the voltage will just drop dramatically and the tool will stop, or the motor torque will be negligible as if you were using an almost depleted battery. I purchased a couple of the "9.0" triple parallel cell configuration with the idea of using the cases to build decent quality batteries, but even the housing quality is a joke.

Interesting, I brought a knock-off 5aph expecting it to be around the same as a really 3aph for the price it was a much better value than the real 3aph.

Want to know the differ ace between xc3.0 and the xc4.0 will be using it not in a tool but a tire inflator I got two in a pack of the 3.0 for a good price for a tire inflator will the 3.0 be fine what do you think they are M12 Milwaukee battery's. thanks

Since you have some testing equipment. What do you think about the 9.0 batteries coming out?

Milwaukee 12v 6.0 batteries have stopped working on me within 3 months 3 different times. Worst waste of money. Did they fix the problem or are they still giving them away for free with promotional deals?

So the price of the battery when you compare and you do 4×6 that’s 24$ and that’s the consumer price imagine how much the manufacturer pays for each cells then add a few bucks for the electronics and the plastic moulding for the casing and you have probably a 15 or $20 battery that they sell you 80$ 😒. That’s why I’m always looking for deals because the prices are crazy 😳.

The only problem i see with knockoff battery that looks close to the original probably isnt going to last you in the long run

Just wanted to confirm that I experienced the same results using the amazon brand 6.0 with my m12 under hood light. Milwaukee advertises 4 hour runtime with XC 4.0. OEM XC 4.0: 3 hr 30 mins (this was brand new out of the box) Amazon brand XC 6.0: 2 hr 40 minutes Amazon brand cp 3.0: 1 hr 22 minutes So we can guesstimate that the 6.0 is more like a 3.0 and the cp 3.0 is more like a 1.5ah.

I go with 2 of the cheap boys and keep one charging

You are showing 5, 10 and 15 Amps scales, but… how many Amps does a Gen 3 M12 Fuel Hammer Drill pull at different tasks?

I wish these Chinese companies just were honest with the batteries, you can open it up and see they are using 2ah batteries why lie and say 6ah. Like you said they are still a fair price for what they are at this point I feel like they are just upping the Ah to complete with each others fake numbers

i think the biggest problem with the knock offs is the marketing of them at 6ah batterys, if they just slapped a 3 or even a 2 on it it would feel less like a cheap chinese knock off lol

Your straight up lied on camera lmao, the high output with the purple Samsung cells did the best, but the rubber bottom off brand did almost exactly as well as the non high output 6amp but lasted a little longer even

Kind of confusing...so wk12 is recomended. You held them up but didn't say what they were

Well, the tool should just come with the battery and the charger if you don't want people to buy the knockoff battery and charger.

Strange, my waitley 6ah m12 has pink 2200mah cells which I had to Google to figure out. They are really good batteries for the price...I've had to resolder a connection on my other knockoff. Moral of the story, get genuine batteries for free with promotions

These batteries look like rigid tools old 12v lineup they quit making. I bet i could cause why after seeing these...

Do other people in your area pronounce "genuine" the way you do?

They won’t hold a charge after a few times of charging lol guy I know thought he was getting great deals for the m18 and they are totally trash and few uses on m18 vacuum and they don’t even hold a charge after.

I run real and knock off and don’t notice a difference

Your "milwaukee" xc3.0 is a knockoff. You will only see samsung 15m in a genuine pack.

Do NOT buy these. The clips that hold them in break every time.
