Milwaukee 48-11-1828 M18 XC RED LITHIUM 18-Volt Lithium-ion Cordless Tool Battery

Great battery! I bought this specifically for my job site radio (2790-20), but recently purchased a cordless sawzall and will be using it for the sawzall as well. Additionally, I have two XC batteries that came with my hammer drill (2602-22) and impact driver (2650-22). These batteries last a loooooong time for almost all applications; it seems like each battery will last for several hours doing even mid-level work. So far, the only time that the battery completely drained on me while I was working was when I used my drill to mix concrete (using an attached paddle for mixing concrete in a bucket).

As far as the weight, it's really not that bad and you get used to it quickly. I have used the 18V compact li-on batteries, which are great, but half the amperage; this battery is 2.8 amps and the compact is 1.4. Additionally, if you buy this retail at Home Depot, you're paying $120 + tax versus the $75 here. Totally worth it.

Now comes my critique. I absolutely...Read more

I have a multi-tool M18 kit along with three of these M18 XC batteries. They've been used and abused my me and all my helpers while building a house. The tools have been dropped and kicked around at times, and I've cringed as I've watched tools fall and direct hits taken by the batteries. The little Milwaukee circular saw took a 15' plunge (a new table fixed it) and the battery had a ding indicating it had taken a hit also. I saw the drill/driver take two direct hits. To no avail. They all still lock on properly, they all work properly, they all recharge very quickly.

They've been drained to nothing, or been run for just a little bit then topped off. It seems to make no difference, as they all seem to be running tools just about the same duration after one year of use. The little 1/4" impact driver has seen an insane amount of screws, thousands of 2-1/2" torx, 5,000 1-1/2" washer heads, 250 7" torx lags, 500 5" torx lags, and on and on (that little Milwaukee...Read more

I purchased a couple of these batteries with a four tool combo kit. While the tools seem to be solid and comfortable, the batteries are bit of a disappointment. Why would Milwaukee downgrade the amperage of their batteries from the V18's 3 amp to the M18's 2.6 amp? When Makita has set the benchmark @ 3 amps, it seems foolish to offer anything less. This wouldn't really bother me that much, after all it is only about 14% less, but Milwaukee went out of their way to obscure this fact. Nowhere on their website does it state the amperage for these and the battery itself only gives it's rating in watts, on the bottom in very small writing, 47 watt hours. Not a good way to treat your base who loved the V18 batteries, only to see that line discontinued. I gave it three stars because I think these batteries will probably live up to their expectations, mostly, but feel like I got tricked into buying something that's not equivalent to Makita's LXT, and that is who they are chasing after,...Read more
