You can try warranty services. However, if they are having an event in your area you might just try going down there. I have taken bad batteries to them in the past and they just GAVE me a new one.

What kind of batteries are they? If they are NiMh and haven't been used for a while, they can lose their charge and NOT be sble to be charged again!

Do you have a 3rd battery that does work? Buy a battery to make sure the charger is working or that the drill is working. If yes to both of these, then your old batteries are NFG.

As far as a schematic goes, I would guess that it is proprietary in nature and that not even dewalt "repairs" them. I wouldn't be at all surprised if the same model had several different versions of circuit boards representing different production runs

I'm assuming you have a DCD970 as DeWalt doesn't have a DC970 and the DW970 is an impact driver. The chuck on your drill is a new design that doesn't have a lock screw inside the chuck, they are put on very tight with lock-tite to hold them on. They are made to be taken off with a special chuck holder and vice jig that only service centers have. The allen wrench method used on older chucks won't work as the chuck will just loosen when you hit the allen wrench. I have on occasion removed one by doing the following: Turn the chuck fully open then secure it in a vice with the drill straight up. Holding the drill body and using the handle for leverage, turn the drill counterclockwise, as you are looking down on it, with steady, strong pressure. If the chuck breaks free it will spin off easily. If you are at all afraid you may break the handle you may have to take or send it to a service center to have it removed.

I DON'T KNOW. COULD BE UNDER WARRANTY FOR FREE REPAIR OR REPLACEMENT. I HAVE RYOBI AND UPDATED ITEMS. THEY HAVE 3 CHARGERS 2 SMALLER RATED CHARGERS WOULD NOT GIVE ME
'FULL CHARGED' LIGHT. OLD BATTERIES WOULD NOT CHARGE ON OLDER CHARGER. FROM INTERNET ADVICE, I REPEATEDLY PLUG AND UNPLUG CHARGER BY HAVING PLUG LOOSE WHEN DOING THIS. SOMETIMES IT TAKES 4 TIMES TO CHANGE FROM DEFECTIVE TO CHARGE. SOMETIMES IT TAKES 20 TIMES TO SEE THE CHARGE LIGHT.
