Tested The Counterfeit Milwaukee 3.0 Vs The Real And The HO CP2.5 

cp2.5 uses high discharge samsung 25s cells that are rated at 25 a continuous 25 amp discharge rate and the cp3.0 uses sony vtc6 or samsung 30q cells rated at 15 amps. Because of this the 2.5 will have more power and less voltage sag and will be superior in high power drain tool like the m12 stubby or the m12 circular saw and the m12 hammer drill. but the cp3.0 will be superior in low power draw tools like lights, heated gear and so forth.

Great video, just found the 2.5 H.O. at Home depot 79$can. Works great in the Hoodia heater.

Thanks for the follow up! Brookfield spelled wrong on fake, also said "or" instead of "and"... My CP3.0 from Home Depot also has Murata cells.

Thank you! Big difference from fake to real..plenty of fake on ebay being sold. As for difference between real 3.0 & the new 2.5, not much

My CP3.0 and XC6.0 both have the same pink Samsung cells. They are the only 2 M12 batteries I have and need. I have 5 of the tools too. Thing is, I only need them for DIY and I only have 2 hands haha

One big giveaway is the missing screw on the bottom. Only takes a quick glance to check that.

I’m sold!!! Counterfeit is no bueno

I got a couple "fake" cp3.0's that last no longer than my cp1.5's, but they were stupid cheap. Not worth buying anything on eBay anymore.....

Ok Yes your right the extra 10 is worth because of the Sony 18650 batts. Now I buy and use fake m12 batteries because I do a lot sawing in dirty spots and I pay 54 dollers for two 9.0mah batteries the only problem is sometimes the clips that hold it in break but I just have it exchanged and once it was to late so I bought another set switched the tops were the clip was and was able to get them replaced but now I have four 9 mah two 6 mah two 2.0mqh and one 4.0 that came with the saw

Would you recommend these? Just bought a impact driver and it comes with a battery but I wanted to order more for backup.

The 2.5 HO are out for sale at home depot(online) offer $99 for 2 pack

Thanks man! I've gotten some very, very convincing fakes from both eBay and Amazon. They're scary close in appearance. I'm still not sold on these HO M12s. For 10$ more. I was skeptical to begin with given the size constraints m12 comes with. There was no way they were gonna fit 21700s inside. Awesome testing. Looking forward to the 5 vs. 6. That one may have some difference. But I'll stick with the 3.0 myself for the smaller dudes. Typical typos on the bottom sticker of the fake. Brookfield vs Brookidid WI. Update - there is a difference.

I'd really like to see how the waitly 9.0ah battery would test, it definitely has an advantage with an extra row of cells. Also seemingly lasts twice as long as my 4ah batteries

The fake also doesn't have a screw in the bottom

Actually, if you do your temperature calculations in Celsius (e.g. set your zero point to the freezing point of water), then you will see a 22% drop in temperature vs. the CP 3.0.

Do you remember where you got that counterfeit battery? This damn battery has been intriguing me ever since your vid where you discovered the Ah discrepancy.

Did you notice it says "Brookfidld" on the bottom?

Why the discrepancy in runtime between the CP3.0 and XC3.0? If theyre both rated or advertised as 3.0Ah shouldnt the runtime be equal in theory? It wasnt even close!

The M12 logo looks different..

Waitley batteries are legit. I buy them for myvM12 lights.

I knew something wasn't rite cuz I have two cp3.0 and they both get 3ah runtime for me. It should be the same cells as the xp6.0

Chin-Waukee nefarious batteries up to no good.
