  • Awesome battery
Awesome battery for it to have the power of the12ah in a 8ah size is insane, I could tell the Difference in my power head/trimmer. The size makes it easier to get in tight places, Altogether the Milwaukee forge is a great improvement from the first generation. Awesome battery

  • Powerful
I use this battery for powering a chainsaw. Last up to two hours for steady limbing/ pruning. Excellent value. Hope the tariffs don’t drive up the price.

  • Strong with a catch
Power boost for my 2767 impact, but makes it lag at startup. Apparently it is a common issue with some of the older model impacts, but only this new battery makes mine do it. Don’t have that issue with the older batteries. It is a genuine Milwaukee battery, and it works, though, just be wary if you have an older impact. ... show more

  • Great Bachup Battery
These are a bit pricey, but they are the Milwaukee “real deal!” They routinely outperform the 6.0 and 5.0 AH in spades.
