I have a 12v drill which always seems to run out of oompf at the wrong time. Has anyone tried charging these batteries from a boat's 12v supply? - B&D (who made mine) do not seem to have a 12v charger kit.

Never bother charging mine on board - I have made up a lead to connect to my 12V socket and has a pair of spade terminals to fit to the contacts in the drill handle. Cable tie the lead to the case and I then have a 12V drill with a 200AH rechargeable battery with a lead long enough to reach almost the whole boat.
Have a look at your battery contacts this might work

You could run it from a 12volt supply onboard, but charging it from a 12volt supply I dont know, but I guess it's possible, they do it for VHF etc. unless you go the 12v-220v inverter route.

Check the charging transformer, I expect the output is about 14.5 volts for a 12v battery. If your boat batteries are close to the required level then replace transformer with direct supply from boat and your battery gets charged. I carry a 9.6v battery which has a 12volt charger - ideal for the boat. Lets face it they are not expensive so treat yourself to one that you can charge.

Most battery drills ...
actually survive running direct of the boat system. The only thing is I found to make sure the battery is disconnected in the drill - better is to take it out and fit a dummy.
Even 9.6V drills will run of the 12V direct .... never had problem with the cheap B&Q one I had - till someone else dropped it in Langstone hbr !! It just ran a little quicker !!!!
Why bother charging on the boat if you make a wandering 12v lead .... it makes the drill lighter as well. Use the battery and charger for home work !!!!
