THIS BATTERY.......
THIS BATTERY......... I was a bit skeptical about this battery at first because of it's price point. It sold at a fraction of the price than anywhere else in town. With that being said, I do residential remodels and renovations as well as industrial maintenance work. I've used different brands of tools throughout my career(25+ years) and I won't name names, lol. Milwaukee has outlasted all other brands and I highly recommend them. The current job I'm on, I'm basically rebuilding this mobile home and it's me and one other guy that just started using Milwaukee. He got the drill, impact and 6 1/2" circular saw. His combo kit came with a 1.5 amp and a 3.0 amp. I have a 1.5 amp, 3.0 amp, three 6.0xc. Both of us running circular saws, sawzalls and impacts, the army of batteries just couldn't keep up. I'm the type of person that shops around and tries to find the best deals and I came across this beaut. After a little bit of arguing with myself and my experience with Milwaukee won 😂. This battery has more power which means more run time and less downtime. Functions flawlessly. If it's a Milwaukee product(which it is) you are going to get a high quality product. It fits all M18 tools including the packout shop vac. It is slightly heavier than the 6.0xc batteries but the little extra weight is worth it. The durability of it is it does last a lot longer than the 6.0xc batteries but I don't know how it holds up to physical abuse of being accidental being dropped, knocked around in the work truck, etc. I recommend this battery to run the more demanding tools like the shop vac, circular saws(6 1/2" and 7 1/4), angle grinder and the multi tool. However, I only have the traditional battery chargers and when I received the battery, it went onto a charger because it had one bar. It took 3 and a half hours to charge it. I recommend the rapid charger, which has now been added to my " To Get" list. ... show more

Verified OEM Battery
The Milwaukee M18 REDLITHIUM FORGE XC8.0 battery is an absolute powerhouse and easily one of the best upgrades for anyone heavily invested in the M18 platform. The performance difference is noticeable right away, especially on high-demand tools like grinders, impact wrenches, blowers, and saws where consistent power really matters. What impressed me most is the combination of runtime and reduced weight compared to some larger high-output batteries. It delivers excellent power without making tools feel overly bulky or unbalanced. The battery also runs cooler under heavy load and charges incredibly fast when paired with a compatible rapid charger, which is a huge advantage on busy jobs or long workdays. Build quality is exactly what you’d expect from Milwaukee—solid, durable, and jobsite ready. The battery gauge is easy to read, and overall reliability has been excellent. If you use M18 tools professionally or just want maximum performance from your setup, the FORGE XC8.0 is absolutely worth the investment. It’s quickly become one of my go-to batteries in the rotation. ... show more

OEM New in packaging! A+ Performance.
I've bought two of theser batteries. They come new in OEM packaging and work flawless in my blower. Two XC8.0 Batteries last a long time blowing a large drive / sidewalks / all landscaping etc. A++

Excellent battery. Completely satisfied with the purchase.
Very satisfied with this battery. It is the new type that has better ventilation and holds up well.

An exact factory fit!
My Milwaukee leaf blower is perfect, except the battery runs out too fast. Having a second battery means I can work non-stop - the battery charges in about 45 minutes and is ready when the first one runs out.

Works as intended doesn’t seem to be a knock off.
I’ve had this for like a month or so it takes a little while to charge. It seems to be a real Milwaukee battery M 18. Price was right. We will see how long it actually last but it’s enough power for me to do what I need to do in my yard with my weedeater.

Better battery life
This replaces my M18 12.0 amp and has a longer battery life. Also it's smaller and lighter.

Top Performer
The Forge battery is phenomenal. I have a few of these and they all exceeded performance expectations.
