waitley2 Pack 12V 6A Replacement Battery Compatible with Milwaukee 6.0Ah Power Tools

So far, so good. I really can't tell difference between these and the OEM ones.

Best Buy under $35 for 2. Dependable, delivers good power for longer.

I have been using them for quite some time and the build quality and battery life is impressive. Battery gauge however is not very accurate. Great batteries if you are running tools that just need an extended battery life such as the M12 tire inflator. I have used them on my m12 fuel impact with no problems as well.

This is my first set of knockoff m12 batteries but these seem to have the best reviews. I got them and immediately put them on the charger. One charged and one would not, but i got it to charge after removing and putting back on charger. I’ve used nothing but these all week at work and definitely seem to have longer battery than my 4.0 Milwaukee brand batteries. This review is only after one week of use so we will see how long they hold up

Works as good as Milwaukee

These batteries fit perfect and charge quickly. They work well in my new project and look to be durable enough. They are compatible to my Milwaukee drill and I don't have to pull very hard to release. My old battery did't have the base so now my drill stands on it's own and has a longer power duration.

These work great with the Milwaukee stubby impact wrench I have!

They definitely work, but because they are not authentic Milwaukee, the tool loses a little bit of power.
