  • Little battery big juice
Great little battery's I've bought several so far. Lot of juice and gets the job done.

  • Milwaukee Quality, Until ...
I have had more failures with Milwaukee batteries and battery chargers than with any other brand of gear of any sort, ever, in my life! But the power tools themselves are unbeatable. I think I'm on my fourth charging station and this battery failed for no reason; it started blinking red / green while on the charger. Replaced with a new one (this Amazon item) and all is well again. Unreasonable mysterious failure rate. But it's come to be expected. I'm in too deep to switch. I'll give this battery five stars because, until it fails unexpectedly, it is an excellent part of an excellent system. I received a brand new item which charges as it should. I guess it's that time of year to suffer the Milwaukee's got me by the battery again blues ... Carry on friends! ... show more
