    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.

      Purchased this at Home Depot and it lasted 10 days before it would not charge fully anymore. I tried to get a new replacment throigh The manufacturer and just kept getting the run around. I have lots of Mulwalkee products andwill not buy any more high output products.

        A must have for the Milwaukee weed trimmer (2725-21HD). One battery isn't enough for larger properties, so having a second battery on hand is great. Took me about an hour to fully charge using rapid charger, and lasts about 30-40 minutes with my weed trimmer on high speed mode. The only drawback is the price for one of these high demand batteries.
