    • 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

    • Appear to be legit Milwaukee batteries--May not have a warranty though
Considering the normal retail price of these 8.0 A*hl Milwaukee Forge batteries, I was expecting this to be a counterfeit. Amazingly, these are the real deal in the authentic frustrating packaging. When I took the pack apart, the cells, circuitry and plastic are identical down to the mold marks. Tested capacity was 8.1 A*h. Try as I might I could not. find anything fake or inferior about these batteries. They are simply a good deal. Seller did not respond to my question about being an official Milwaukee dealer so you can infer what you will. Most likely that means you would not get any warranty at a Milwaukee service center. ... show more

    • Great upgrade
This battery is a beast. Not much bigger than the 6.0 HO but definitely longer run time. Turned my 1/2” into a honey badger and works well with the 1”. Since it’s a Milwaukee it fits how it’s supposed unlike the off brand batteries. So far seems just as durable with it being dropped a few times and swing around on an impact but only time will tell. ... show more

    • Good powerful battery
This is my 2nd forge battery I bought for my Milwaukee tools, first battery I bought off my tool guy at work and the battery is definitely stout! It has plenty of power and will last almost all day when I’m using it. Battery is on the heavy side though.

Idk if it’s real or not but it doesn’t last as long as the original one I have. But does what I need it to do.

    • GREAT battery!
This battery is awesome! Lasts sooo much longer. Used for many hours over the weekend with pole saw and hedge trimmer. Didn’t have to charge once and still had two bars.
