I've got an 18V B&D cordless drill and a selection of battery chargers but am not sure which is the right one. B&D's website just wants to sell me another one. The most likely candidate has an output of 24V AC. I don't really want to blow the thing up by sticking AC into a DC socket so can anyone help? YOu might guess I'm not very electrically minded.

Thanks in advance
 
You may well find that your batteries are tired, and it may be a question of buying a new drill, as B&D and many of the cheap jobs on the market supply cheap rubbish batteries, which normally fail well before the drill does - so you may be wasting your money buying a new charger!
 
On my old B&Q 12v drill, when I found out that new batteries were not available, I removed the old batteries and rewired it with a lead to use on the boat via a 12v cig lighter socket. So I always have a drill on board. Fits nicely in it's original plastic box complete with a selection of drill bits.

Yes thats really useful, but my drill - and the batteries are going, is 18V - would that work on 12V? or would it be just too underpowered?
 
The B&D 18 volt slow charger which I happen to have here says 21.75 volts DC, 210/230mA Part number 311903-26 (HKSD-012272)

The plug/slide on cap that fits the battery also clearly says 18V on it its top, and has a slot in its bottom face that a peg marked 18 on the battery can pass through.
