Anybody know if this battery fits the Denali brand of tools? Specifically - the the Denali electric chain saw ? (sorry don’t know the model number)
No - Milwaukee M18 is Milwaukee M18. Adapters may be available to convert from one battery platform to another, but for the most part, power tool BATTERY BRANDS DO NOT INTERCHANGE.
Amazon’s Denali lineup was made by Skil, an aspect in which they advertised. If it’s the 20V that was sold here a couple years ago, look for a corresponding Skil PWRCORE 20V battery.
(Note that I am not staff. I just volunteer to help out on the forums.)
