I have an IBM thinkpad with a 9 cell (nominal 10.8V) Li-ion battery.
The AC adapter (wall wart) is nominally 16.8V (measured 16.0V open circuit).

I have available a Toshiba AC adapter with the same plugs, except that
it is 18V (nominal and measured).

Does anyone know if you can use an 18V adapter in place of a 16V adapter?
If so, what's the info that says it's OK to do?

Searches with google for battery/battery charger specs haven't been real
helpful. I did find

http://www.bixnet.com/unpowbat.html

which has a dual voltage 19/16V adapter which they say to set to either 16V
or 19V according to the system you're charging. They don't say that you'll b
low
your system if you use 19V when charging a 16V system.

Thanks Joe

I wouldn't advise to do so. The lapdog could have something against it,
your battery can have something against it, and warranty won't help.
Get the _correct_ adapter.

Probably it will not work. I have a laptop that req 15 volt and I connected
a 16 volt adapter and it would not start at all.
You could get a cheap adapter that handle 6 > 25 volt settings.
