Most of us know that Black and Decker is the low end of DeWalt . I buy the battery for the B&D 9.6V and cut the keys off that keep it from going into the charger and drill. There are 2 areas that need to be removed: 1 above the battery compartment and 1 at the top. I have been doing this for more than 2 years and it saves about half the cash.
