Charging batteries - test-drb@ccmp.vtda.org

...
 To charge a 12V battery with a 22V power supply
suggests some internal 
regulation, in which case 14V probably wouldn't work.  On the other 
hand, it probably would do no harm. 
What if I hooked the charger directly to the batter?  Would the extra 2v 
be a problem?

...
 You don't say whether the 22V is dc or ac - if
it's ac, dc might work, 
but if it's supposed to be dc, ac could damage your machine. 
Both the intended adapter and the one I have are DC.

...
   P.S.  Anybody
have a 22v, 0.82A adapter for sale? 
I could build you one, but shipping it to the US might be expensive :-) 
I'll probably end up with an explanation that's way over my head, but - 
How do you build one?

Thanks.
