I got the cure for all those batt. and charger problems. Buy dewalt. I used to be a contractor and Im telling you-DEWALT rules for long lasting and hard working. Mine 14.4 v one is so old -its the first model they made. Been dropped from step ladder 4-5' to concrete floor, beaten, heated up from continues useage. You name it. Still rocks though. Cant beat that quality..Have one of their saw-zaw's too, same thing unstoppable.
