waitley 2 Pack 12V 9A Replacement Battery Compatible with Milwaukee Tool

Used it with in 5 minutes of charging and I Love this battery as now I can get a lot more done without having to change out a battery because this thing lasts forever and it seems give my ratchet a little boots in torque as well. I will definitely buy more

Fantastic batteries the biggest downside of them is I think since they are such high amp hour, they burned out the charger that Milwaukee gave me with the drill

They work great. I've been using them in two die grinders, and they have been fantastic so far. They stay charged, they last all day, and they charge fast

Well, i have a few months with these. I am barely and slowly moving towards Milwaukee. Both m12 and m18. I tries these for the Milwaukee m12 fan since i don’t know if these can handle a high powered tool. So i tested my 4ah OG battery and the fan lasts around 3 hours on high. With these, it almost lasted 7 hours. They fit in perfectly and had no issues with the insert. Also, i do love the light indicator. Why didn’t they add that to the OG batteries? Anyway, good starting batteries for someone new, if you already moved to OG batteries, use these for a fan or lights. Still worth it.

Batteries are HUGE of course. They took close to 2 hours to fully charge (from 50%) on a OE m12 charger. It completely changes how my stubby impacts work (much stronger, was using only 2.0 OE batteries). I do not know how long they last just yet, but I do plan on making a follow up review after I’ve put them through their paces. Daily work at a dealership should be a great test. (Update 6/2020) Within the first 2 weeks, 1 battery began to not work properly with any of my tools. I’m guessing it had a shorted cell, so I returned them, and got the 6.0s instead which have been flawless ever since. Update, on a 1/2 m12 stubby with constant use it’ll last about 2-3 weeks on a single charge. Using a 1/4 impact driver, almost forever if you leave your tool on power setting 2. Overall a fantastic battery, just try not to drop it because the plastic is a little bit more brittle (don’t use brake clean to clean it and you’ll be fine, I made the mistake so you don’t have too lmao). Overall very happy with the battery, I guess I was unlucky with my first one. If you get one that’s bad out of the box, it’s pretty easy to return. Just get the next one. For the price, what you get is amazing. Very happy I gave the battery a second chance after my first one.

They don’t stay in the tool very well. The tabs are breaking off the ones i got and they were bought in may.

Here is my experience with the battery’s I use them for a Milwaukee under hood light I love that light because it’s bright and my eyes just are not what they used to be. They will run that light with it on for 8 hours and 10 minutes before that battery will die and with the Milwaukee fast charger it takes 1 hour and 45 minutes to charge to full the batteries have changed a little my batteries do not have any buttons or a status light. I bought the batteries is August of 2022 and just last week they will only last 4 hours. And that’s 4 years that’s amazing for a aftermarket battery so I know they use really good cells in the packs I would buy but money is tight right now so I might have to try and find cheaper ones. And buy the way 4 years ago the were $50.00 dollars and 4 years later they have only gone up $5.00 dollars now that’s amazing. I am a professional Chevrolet technician and I do heavy line work were I am under the hood some days all day for a week doing a diesel engine catastrophic fuel system repair. This what I know from my experience.

Good batteries work very well.The clips that hold the battery in do not last long.Manufacture must work on this process for it to work better.Because lot of money to buy these batteries and to have to keep buying the clips break in the batteries , keep falling out
