SOURCE: I have a Black and Decker 7.2 V cordless drill
Center pin is generally positive - outer ring is negative. But you can use a 9v charger just as easily; in fact, the one supplied with the cordless drill is a 9.0v, 200mA output charger.

I saw them in the latest Metabo leaflet. They are serious producer and they shoudl keep spare parts for few years after they discontinue some product. Try to call to Metabo in your country. Juraj
SOURCE: Will a 12 volt slide
This close to father's day you should be able to buy a new drill for about the same as a battery. The 12v would overheat the motor if you ran it for an extended period.
SOURCE: what is the polarity of a 12v Black & Decker Drill?
centre pin on plug socket is usually positive...
think I would **** it and see ....if the replacement charger has a charge light it will probably not light if you have reversed polarity. Had the same problem with VHF portables ...I just cut the wire on new charger and tried both options ..reconnected and a bit of tape...voila.
There is little danger to your drill from getting it wrong as long as a the timing is relatively short.
