  • Good quality and holds a long charge
Really adds the weight to the tool you are using but it packs a lot of juice when fully charged it lasts and lasts

  • Works as it should
We were skeptical at first. The performance is good as the other milwaukee battery packs. Its as heavy as the OEM and lasts just as long. We are good with it and the price was right too!
