The notebook probably has internal circuitry to monitor the battery
and regulate the charging voltage.  This would be the charging system.
So in this case, they are not the same - which is why the AC adapter
can be 16-18V for a 10.8V battery without overcharging it.


So back to your original question - you would _probably_ be ok with
the 18V charger...but assuming the notebook is fairly expensive, I
would not risk it.  I rely on my notebook daily...so I'm extra careful.
