Guide :Drills : 12V XRP Battery Pack
Holding battery charge on 12v DeWalt batteries
I have both 12v and 18v Dewalt drills. The 18V is outstanding, but the 12V will not hold a charge on either battery. I can charge it up and it works fine for a while, but even on a full charge, the next morning it is down...both batteries act the same....the 18v drill holds the charge just fine.
