        When using them in my string trimmer, the pins in the battery melt making them very difficult to get out of the string trimmer and to recharge.

        Great Batteries. A good package deal
        They have worked great and has delivery the extra power needed. You can instantly feel the extra kick comparing to the regular CP2.0. when getting project done. If you just need a little more but not a bigger battery that will make your drill heavy, then this Xc3.0 its what you need. Just enough juice to get your project done in one day. However, it does take forever to charge but still a great battery.

          It's an awesome piece of equipment but the only thing is for the free battery make sure you bring it up at the same time and the people there don't seem to know anything about

            Battery Dead after a little over one year..
            I have been using the battery for a little more than a year, I take good care of it. It stays inside the climate controlled house. The other day it only shows 1 bar of charge; the charger light turns green but there is only one bar charging. I’m very disappointed and never had to deal with Milwaukee customer service before, depending how that goes it might be time to bite the bullet and move all my tools to a better platform.
