Good question.  In the states it looks much different where the 4.0 is much smaller and I think it's on the right side.  Something does look off with yours.

hi, is it supposed to have a manufactures seal on it?

the website I got this on in France claims I need to pay an expert for a evaluation to prove it over heats, it gets very hot, so bad that it appears as if there is smoke and then its hard to take the battery off, im worried it will melt into my m12 fuel hammer drill

By cement you mean the mortar between bricks or concrete? 

yeah its exactly that, an apartment like studio with concrete walls., music rehearsal room.

Just swapped my Bosch 12v for a fuel 12v multi drum head kit (and a huge plastic suite case for the set) nothing is cheap by Milwaukee Tools, i watched dozens of videos on youtube showing people drilling into concrete etc with a 12v , so i was sucker convinced before actually trying it myself

 

 Notice that the battery says XC 4ah 

i went and got this (i think its counterfeit) and the best i get into concrete - cement walks is 1/4 inch 😢 

 

my other batteries are normal 2 ah, two which came with a fast charger (i got the dual 12v and 18v ) as i also own a Milwaukee jigsaw fuel as well., im sad cause i cant see how much bigger a 18v is compared to this 12v, the bosch where really compact, solid, def could not drill into cement at all, so how did this guy in the video do it only leaves me guessing its a bid or battery.

Same boat here, need answers, the only info i found was on a ebay thread https://community.ebay.com/t5/Buying/Received-counterfeit-Milwaukee-batteries-and-my-experience-in/td-p/31645941?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5337259887&toolid=10001&customid=10e18918a37611ec9a3c9af788fc54630INT
although they are 18v versions notive the round logo

Ok, first I must admit that some of my Milwaukee “look-alike” counterfeit batteries are in this mix. Here’s what I am seeing. Some of me small M12 batteries are giving me the red-green no-good flash when charged on my newer dual purpose genuine Milwaukee M12 and M18 charger. But if I put the same battery on one of my older M12 only chargers they charge normally. The voltage, checked with a Milwaukee M12 DVOM is 7.7 VDC. Why?

Also, I have a new counterfeit M12 that placed on the charger flashes the red-green blinker of death. New, right out of the box. They came as a pair. The other battery charged normal. The one that blinked r/g tested at 20.2 VDC.  Weird! 
Any suggestion or explanations? Do Milwaukee chargers have kill-pill programming that can detect Chinesium contaminated batteries?

I purchased the battery on a website in France called the leboncoin, I noticed the logo is completely different, I looked on Amazon for 4aH Is located in the center of the sticker, but on mine its the left, The reason I was suspicious because after I got it home I could not drill into it cement at all, And I was refused to right to return it, I raised the claim on this website and they’re only giving me 48 hours to show proof the battery is not counterfeit..

 

Please advise
