  • There are different size batteries produce for Milwaukee's 18 volt products
Battery is very durable and I choose batteries of this sort because they are lighter than a battery that's got a higher amp rating

  • Just as advertised
Great price for an amazing product! When I saw the price I thought it was gonna be for the fake china ones but I was wrong, these are the legit Milwaukee ones and for a discounted price you can’t beat anywhere else! I love them

  • Genuin Milwaukee 👍🏻
Super light, compact and with the excellent power punch of the high output battery👍🏻. Excellent choice for drills and 1/4” impact drivers. I won’t waste any time on the standard capacity batteries again.

  • Genuine Milwaukee
Came in genuine Milwaukee packaging. Battery cells and circuit board were also genuine Milwaukee. 3.0 HO batteries are the best for daily use on a drill or impact simply due to weight and size. Just have spares to swap in. the high torque 1/2 also doesn’t seem to mind them but the bigger batteries are better suited to the high torque. A 3.0 HO last easily all day in an auto shop. ... show more

  • Not as tall but wider than “regular” batteries
This battery is wider than the usual 18 volt Milwaukee product. The reviews that mention it is incompatible with a belt hook on the side of the drill and impact driver are correct. The battery is not as tall as a “regular” Milwaukee 3 or 5 amp battery but it is wider. What you get is a 5 amp battery that is as tall as the “regular” 3 amp battery but wider! Aside from the fit problem, it is a good battery well-suited to the multi-tool, grinder, saws, etc. ... show more
