Drill runs slow after the batteries are completely charged. Does this mean the motor is fried?
Its much more likely that your batteries are not charging up properly. Ni-CD batteries suffer from 'memory effect' and can appear fully charged when only 70% charged. Also they lose charge when being stored. Do not short them out to discharge them! Wait until the drill complains that they are flat and then recharge them rather than when they first start to slow down. Do not let become completely flat (less than 1 volt).
SOURCE: Black/Decker 12 v drill charger will not charge
If the battery gets warm after being in the charger a while and still is not charged, then the battery is bad
if the battery stays cool in the charger then the charger may be bad
Chargers usually have a light code, I.E. on means charged, slow flashing means charging, and a quick blinking means bad battery
Some chargers have 3 lights and the code should be imprinted on the charger.
hope this was helpful, cb
SOURCE: Won't charge fully
If your warranty has expired, you're best off buying a new drill. Replacing batteries will quickly add up to the cost of a new drill.
I know they cost a lot more, but, if you want something that will last a lot longer, look at a Milwaukee, DeWalt, Makita, Bosch, Hitachi for your replacement. Milwaukee actually guarantees their LiIon batteries will last 1,000 charges or longer.

I'd put penetrating oil in it and tap the chuck with a plastic hammer. That should free it up.

SOURCE: Black and Decker corded drill won't tighten around a bit.
the chuck sounds like it is bad or maybe stuck from rust, what you can try and do is spray some WD-40 on the jaws and then try and holding the collar with a glove and run the drill SLOWLY in forward/reverse and see if it loosens up if not you will need a new one.
