Sometime last year I established that the charger for my 18v Site combi drill should also (because it was intelligent) charge my 12v batteries for my two B&D drills.
Looking inside the Site CA18 charger body there are +ve and -ve terminals plus 3 other terminals, two of which match metal contacts on the battery.
I was hoping just to construct a pair of leads to go between the charger and the +ve and -ve terminals on the B&D batteries.
Does anyone know what these extra contacts are for?
Cheers
