Old Makita Drill

I have an old cordless Makita drill the water guy left at our house 15 years ago, I found in my shed with the charger :-). The battery is pretty much completely dead, and I don't want to buy a new $40 one or zap it with a welder. How can I turn it into a Corded drill or use a different battery with it? It is the kind that stores the battery in the handle. 9.6V Battery.

Theoretically if you match up the output of the battery you should be able to run a wire straight through the battery compartment.

1. Check the output of the flat battery, find a way to convert(transform?) AC power to that output.
2. Open the battery and take out the batteries, then run a wire from the battery circuit board contacts to AC.

(Assuming the battery pack is configured with a battery and circuit board.
