I've got another M12 3.0CP flashing green/red after being depleted in heated gear. Per my notes on the battery, I already warrantied this one 3/19.
I had had a couple other 3.0 CP's fail around that time, too.
What was interesting is that I have two Rapid Chargers in the house. For a while, one would flash green red and refuse to charge while the other would still charge it. Now both chargers refuse to charge it.
It would seem chargers have different thresholds for low voltage depletion, even if it's maybe .1 volt?....and if different batts cut off at maybe a .1V variation it compounds to an error situation?
Just a theory...
Hey guys, sorry for the newb question, but I just got my first impact driver and I'm wondering if this noise is normal when shaking the tool? I'm assuming the noise is coming from whatever is used to create the "impact".

I'm getting my RED Christmas packages in drips... some were pushed till December 29th...Take a USPS Priority Mail box or envelope with a pre-printed label. You can create a free USPS account if you don't have one and print labels. If you don't use the label you can go back after the flight and get a refund. Works better than the stamps that are void if you try to reuse on a different package.

Priority mail is air, lithium batteries can’t ship by air. You could do the same thing with a first class package though.
...Its about time I start using the heat on my jacket, and I’m NOT spending $100 on 2 genuine m12s when I can get 4 aftermarkets for half that.
Anyone tried or tested any the newer 3.0 (some even claiming 3.5) compact aftermarket m12 batteries. Its about time I start using the heat on my jacket, and I’m NOT spending $100 on 2 genuine m12s when I can get 4 aftermarkets for half that.
I wanna get at least two new ones and dedicate them for the jacket.
I’m itching to buy them, so I dunno how long I can hold off for an answer... I’m trying here...
Something that's worked for me is to put it on the charger multiple times. Put it on till it starts flashing, take it off, then put it back on. Usually after 3-4 times it'll start charging it normally.
If you work on your own cars and know every nut and bolt then that is the beauty. I moved out of flat rate and I to another field so that left me to figure out what I needed. With the exception of possibly a friend's Honda crank bolt the M12 stubby will do literally EVERYTHING on the cars I own which are all well maintained CA cars so never dealing with rust and whatnot.I agree 100%. That's exactly the reason why I went with only two impacts: the 2555 stubby and the 2767 high torque. I've only needed to break out the high torque once, and even that gun had to hammer on the fastener for a bit, so it would have definitely been out of the range of the mid-torque. It's funny reading comments about how "big" the 2767 is... Only a few years ago a guns that were half as powerful as this one were as big or bigger!
Should have bought some of the 3.0's when they 2 packs were on sale for $70 earlier in the year.
As far as the aftermarket batteries go. 3.5's are possible to make with legit cells. They don't provide enough power for higher demand tools, but depending on which cell was used it would probably be fine for something like a heated jacket. They do make me nervous though. There are a lot of of knockoff 18650's out there. They might look ok on the outside. But on the inside they are really junk batteries with legit looking wrappers on them. Maybe you get a good pack, maybe they're overrating the capacity of good cells, or maybe you get something with bad cells, or a poorly manufactured pack that will short out and cause the batteries to vent or even potentially explode. If we were talking about a handheld tool, or especially something like a light then I might be willing to blindly take that chance. But for something that's held right next to my body and potentially buried under multiple layers of clothes I'm not so willing. If those cells vent you could be badly burned by the heat produced. By the time you realized there was a problem and started to peel off layers it would be way to late. If they ignite it would be like have a torch turned on in the battery pouch for a couple of seconds. It's not something I want to experience myself.
And just because someone has had luck with a "manufacturer" before doesn't mean something else with that label with be ok. They may get decent cells one day, and bad ones the next, they're buying what they can get cheaply, and there is very little quality testing going on. And people will even make knockoffs of the knockoff brands. It's always going to be a crapshoot on what you actually get. The only way to be sure it to take the pack apart and test the individual cells to try and figure out what they are for sure. That's not something most of us are setup to do easily, if at all. So while I hate paying the ridiculous markup on batteries at times, I also look at it as buying insurance that why I'm buying probably won't try to burn me or my house down.
How can the Chinese be smart enough to make a fake battery that will atleast semi work, but dumb enough to get the label graphics wrong?
This is my experience as well. Money spent on cheap batteries is money wasted. I've tried it with camcorder batteries back when they recorded video on tapes. I've tried it with button batteries for my car remote. My company tried it with laptop battery packs. I have friends who've tried it with car batteries. Never have I seen cheap batteries even give proportionate performance when counting both capacity and durability.
I agree wholeheartedly, but let's be glad they do. One of my bigger fears is knock-offs that look so good you can't tell.
I just ordered some Motorcraft spark plugs on eBay and now I'm hoping I don't get counterfeits LOL
Netflix did a little series called Broken and while some of the episodes infuriated me it starts off about counterfeit cosmetics. The forgers have gotten pretty good about even copying graphics and packaging. So far, you can still tell but it now takes a deliberate, close examination rather than a quick glance as it used to.
I hope other low dollar (ie not Rolexes or the Mona Lisa) forgeries don't eventually get so good that it requires an eye loupe and degree in electronics to tell....
I guess fake Mitutoyo calipers were a thing, and much like M12 batteries, I don't understand why of all things you could choose to copy you'd pick a precision measuring instrument (unlike a Rolex the margins are pretty small)
The possibility of buying good aftermarket M12 batteries has been established long ago. I'm simply asking if anyone has gotten the newer 3.0 or one brand that's advertising 3.5's in the compact form - and can report back. The long shot that anyone has done some actual testing on their capacity would also be nice.
The battery market is flooded with good and bad. As popular as 18650's are its not hard to find something decent. It's not like it was 5 years ago buying some odd size camera battery and thinking it would be ALMOST as good for 1/5 the the price.
Anyone heard anything on the framing nailer? I have been patiently waiting for months.

2 pack of compact 3.0s and m12 charger shipped $83
The charger at least makes me feel like I’m getting a deal, even though it’s useless to me.
Can find them on ebay for $70 (or a few bucks less) shipped if patient. I got that same starter pack. Been trying to sell the charger for $15 locally for months & no bites. Not worth trying to sell online cause of shipping. I have 2 now & haven't ever used one of them. I don't know what to do with them.
Yea I have a bunch of extra m12 chargers. They are virtually worthless.
I hate spending this kind of money on batteries. Its such a scam, but I want dedicated jacket batteries this winter, and at the end of the day I’m already this deep in.. I may still buy 2 aftermarkets. I’m planning 2 get 6 hours out of the two 3.0s combined. At least with a real 3.0 I’ll be able to somewhat time the aftermarkets run time against them.

just says early 2020 on there listing


I "screwed" myself with my m18 fuel impact driver purchase. Decided to assemble my own kit; purchased a hard case for the 2853-20, 2x CP HO 3.0 batteries, and a DC charger. All good except...the 3.0 batteries won't fit in the case! D'oh! They make the insides of those custom cases...so...tight...! Now must either modify the case (which will uglify it) or pick up 2.0 CP batteries...
Suggestions? Elegant solution I'm overlooking?

I dunno but the OMT modifies the cases like butter. Although I'm fascinated that one would care what the INSIDE of a plastic tool case looks like.... good luck
