    A:  I love the batteries that are in Milwaukee tools. They charge quickly but more important, they maintain their charge. I used a competitors battery operated system but their batteries would not last. It got to the point where I would keep 5 of their batteries on my truck and they would all loose charge quickly. 1 Milwaukee battery with 1 backup is all I carry now. Tough lesson, I had over $1,000 in the competitors tools/batteries.

        Q:I just bought the extended lithium m12 battery and when I put it in my standard m12 charger - the red light displayed and battery would not charge??

        Answer This Question

        A:  The red light always goes on when you insert the battery. plug it in and let it charge for a few hours. I have a dozen of these batteries....hint, if the charger ever starts flashing red and green, take the battery out and re seat it in the charger....

            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.

                  Great buy.
                  This review is for three 12-volt 6-ampere hour batteries and one 12-volt charger. I don't know why people are posting pictures of automotive parts and equipment because they have nothing to do with this tool combination. If you do the math, the three batteries produce 216 watt hours of power which means that you are paying $1.08 per watt hour which is what I consider a good buy. If you find another deal, it should average out the same as this deal (excluding the charger). Home Depot said that if I ordered in the next 1 hour and 28 minutes that I would receive my order on Friday, but I received it on Monday so only four stars here.

                  GO THESE ON SALE
                  I got these babies on sale tor 189.99. I couldnt pass it up. Ill be using them for my right angle die grinder i just got. I thought the 6.0 were perfect because the die grinder will use up batteries fast. I work as a mechanic at Sherwin Williams and I am constantly taking apart and rebilding pumps and filters. And getting paint off those things aint easy. But with my new tool and batteries it should make things a lot easier now!

                    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.

                      I have numerous sizes. This one is big enough for most jobs using my medium sized tools.
