of course it is. why wouldn't it be?
Depends.
Doing with my older Nikon CoolPix will 'over-cook' the batteries in
about 15-20 minutes. It actually over-heated and warpped the battery
compartment cover.
"They" probably save a lot of money by _not_ putting any
charging/over-charging control circuitry in the camera body.

Any device capable of using Alkaline cells should disconnect when a
power plug is inserted. This is true for any number of devices
particularly radios.
I'm not familiar with the Nikon CoolPix but if it overcooks it's a lousy
design.
GPS devices and cordless phones are left charging forever with no ill
effect.

Sounds more like you have a defective camera.

Thank you for your post. I found this:
http://www.amazon.com/Nikon-Coolpix-Adapter-990-Digital/dp/B00004U8LM
which seems to verify what you said. Here is what the reviewer said:
"My only quibble is not with the adapter, but the camera circuitry,
which requires that you remove the batteries when using any AC
adapter. It will not recharge them, but might cause the batteries to
overheat (according to Nikon)."
Based on that, I will assume that Canon isn't different from Nikon,
and I will remove the batteries when I use the AC adapter.
Good cameras will have batteries you take out to charge.
I can see the Nikon problem. I don't know if my Sony camcorder has that
problem, as you charge with battery in.

On the last camcorder we owned, you had to take out the battery to
access the plug in for the AC adapter. Message there????

Nope. s/camera/design/
I have three of'em. -- all wildly different serial numbers. All
overheat the batteries if left in the camera with the DC adapter in use.
See someone else's followup in the other sub-thread.

FWIW, I emailed Canon support, and they said that it is OK to leave
the batteries in the camera while using the AC adapter.
