You guys having troubles with battery holding a charge old construction trick I was taught doing construction take your battery put it in the freezer for 2 days I know you think I'm nuts take it out let it sit on the table up for a day or two make sure it is not damp wet or cold put it back in your charger and charge it I was taught linthian batteries all do this once you set them on their charge the first time they stay with that charge the way you erase that put them in the freezer
