Waitley - Replacement Battery for Milwaukee M12 12V 3.0Ah 4.0Ah 5.0Ah 6.0Ah 7.5Ah 9Ah

After a few months a several charges battery functions as expected. Fits well in all my M12 tools and lasts an acceptable amount of time. Charge time is comparable to regular m12 batteries. An inexpensive bargain.

Seems well made and fits the tools perfectly. Holds a charge and seems like it is as good as OEM. Time will tell.....

I recently got a replacement battery for my Milwaukee tools, and it works fine overall. The tools run smoothly without any problems. However, the battery level indicator isn't accurate. When the battery shows "full" on its own indicator, the drill sometimes shows it as only 3/5 full. Even after fully charging it, the battery still shows "full," and the drill matches it, showing "full" as well. Despite this minor issue with the indicator, the battery performs well and powers the tools reliably. It’s something to be aware of if you're keeping an eye on battery levels during work.

Works with any Milwaukee tool. No issues after a year of use.

I was doubtful about whether these would work, and I've been really surprised that they work just as well as the originals. I've been testing them in my workshop for a month now, but I still need to verify their durability.
